A 67-year-old Georgian-Polish national arrested for espionage in the northern Greek city of Serres was cleared of all charges on Saturday after a court found insufficient evidence of suspicious activity.
The defendant, who appears to have been in Greece visiting family, was arrested on Friday morning for taking photographs near the Kleisaris military base, on the outskirts of Serres. He told a judge on Saturday he did not know it was a military facility.
His arrest comes after that of another Georgian man who was remanded in custody last week and is due to stand trial for allegedly spying on a NATO base in Alexandroupoli, also in northern Greece, for at least six months.

Serres Toundra is the largest producer of cucumbers in Quebec and offers a superior quality vegetable through environmentally friendly production
Serres Toundra operates in highly technological facilities
www.serrestoundra.com
the desire to limit its environmental impact is manifested by
following its values in sustainable development
the Serres Toundra team began looking for a packaging product to replace its polystyrene trays
To find a solution that would meet a series of criteria combining performance and respect for the environment
Produced and delivered by a reliable supplier
The team first turned to a tray made of molded pulp
the packaging proved to be ineffective at withstanding the moisture of the cucumbers
Only three days after its arrival at the point of sale
leaving the consumer perplexed by the look of the packaging
Serres Toundra had no choice but to consider another solution
That’s when Cascades came on the scene with its 100% recycled, recyclable and compostable cardboard tray
the Cascades cardboard tray retains moisture perfectly
preserving its rigidity and the integrity of the cucumber for more than 2 weeks
Another good news is that this solution generates significant savings in the long run thanks to the elimination of losses during the assembly process
“After a week of testing with the Cascades tray
It’s hard to say that cardboard packaging alone explains our sales growth
but I’m sure it allows us to stand out from our competitors and be favored by retailers.”
The collaborative spirit and agile practices of the two companies made it possible to adjust the producer’s assembly line in less than four days
while minimizing the financial impact of this innovative transition
“The Cascades team deploys its best specialists to optimize operations and reduce the impact of securing a new packaging solution
That’s our way of doing things,” says Jérôme Porlier
Serres Toundra environmental concerns are shared by consumers more than ever
consumers confirms that 55% of them are extremely or very concerned about the environmental impact of product packaging.1
It’s not surprising that Serres Toundra customers appreciate that the packaging is made of 100% recycled fibres and is recyclable/compostable
consumer surveys conducted by Cascades show that cardboard is perceived as more environmentally responsible than any other food packaging material

CA) — Serres Ranch expects to begin harvest on their blueberry farm in Laytonville
California today with blueberries slotted to be available in local grocery stores and featured on menus as early as next week
“We have a great local following for our sustainably-grown blueberries.” Taylor Serres-Murnig
a fifth-generation member of the Serres farming family says
“Blueberry harvest is hard work but it pays off in seeing the excitement over the annual crop and our great restaurant
catering and bakery partners who use the fruit to make unique and delicious creations each year.”
The Serres family has been farming blueberries on their property in Laytonville
for 23 years and has gained a local following for the berries
which are available for about a month each year from June to July
The family attributes the popularity to the quality
which are grown using no sprays or pesticides
and which make their way from the bush to the market in less than 48 hours. The larger-than-average size of the berries is due to the blueberry varietal: Duke Northern High Bush
which thrives in cooler climates and is known for large berries with a delicate sweet and tangy flavor
“During the fall the plants went into dormancy and got a good long winter sleep
The cooler spring provided favorable weather during the bloom
less heat units than we would prefer therefore it delayed ripening ever so slightly
The weather currently is mild conducive to plentiful fruit ripening
The crop looks good its coming along and ripening nicely and we are excited to get these berries off the bushes and into our customers hands!” says John P
Serres Ranch Blueberries can be found from late June to July in Sonoma Market

getting involved with Ducks Unlimited Canada (DUC) was a natural continuation of his lifelong investment in education and dedication to serving his community
De Serres worked in health care for 30 years at the Quebec Institute of Public Health and as a professor of epidemiology at Laval University
He was named professor emeritus when he retired in 2023
De Serres began taking courses for a bachelor’s degree in biology — returning to a career path he’d set out on decades ago
“I actually started in biology when I went to university in 1973
I worked for the Canadian Wildlife Service on the Gaspé Peninsula and Bonaventure Island with a large gannet colony,” he says
De Serres was interested in doing volunteer work around greenhouse gas emissions
but a conversation with his daughter-in-law piqued his interest in wetlands
“She told me a lot of people work on greenhouse gas issues
but not a lot of people are focused on wetlands even though they are so important to biodiversity and carbon capture,” says Dr
I had been donating to Ducks Unlimited for years and I loved how they used science to protect the wetlands
which matched up with my own scientific background
Getting the word out about wetland conservation is where Dr. De Serres truly shines
he penned over 300 scientific papers and conducted countless lectures — invaluable science communication skills that he’s generously shared with Ducks Unlimited Canada
Since joining the organization just over a year ago
De Serres has supported Ducks Unlimited Canada as a representative at last year’s Quebec Outdoor
Fishing and Camping Show and contributed writing to several digital educational story maps for the Ducks Unlimited Canada website
De Serres’ exceptional contributions to Ducks Unlimited Canada and are honoured to name him Volunteer of the Year in Quebec
De Serres in the Ducks Unlimited Canada office at least once a week collaborating with his fellow volunteers
sharing his knowledge and coming up with new ideas
He’s planning on spending even more time with Ducks Unlimited Canada in the coming year
“The group we have here is really enthusiastic and positive,” says Dr
It’s been a joy to be involved in the movement alongside them.”
De Serres has felt a deep sense of fulfillment seeing the impact that Ducks Unlimited Canada has had on the natural areas he cares about
“There’s a marsh near my cabin in Saguenay that was restored by Ducks Unlimited
there were 10 goslings,” he says with a smile
“When you’re part of the organization that’s done the work and you get to see what you’re protecting
it gives you a positive example of the change that can happen
That’s a big incentive for me to keep working with Ducks.”
After years of being of service to others through teaching and medical research
De Serres remains committed to staying engaged in important issues and giving back in retirement
“I see many people in their retirement who are doing activities only about themselves
I want to continue to contribute to the world
There are approximately 3,030 Ducks Unlimited Canada volunteers across Canada. Ducks Unlimited Canada is proud to recognize each of them — including leaders like Gaston De Serres — as volunteer champions and conservationists who make waves and together
create ripples of change by serving with generosity
Join our passionate flock of volunteers and make a difference for wetlands and wildlife in your community

Marine Serre returned to the runway for the Fall/Winter 2025 season of Paris Fashion Week
inviting guests to the La Monnaie de Paris — a historic venue that quite literally produces France’s money
A unique juxtaposition for a young and independent designer
the location aimed to represent Serre’s resistance “in a world run by financial dictates.”

has closed permanently ahead of the 2024-2025 ski season as fellow European destinations tangle with ongoing climate change impacts
Alpe du Grand Serre’s closure threatens 200 jobs
leaving local community members dependent on the resort in a lurch
The Guardian reports that the decision stemmed from Alpe du Grand Serre lacking enough funds to become a year-round destination
nearly 3 million euros have been funneled into the creation of hiking and biking trails at the resort
but local councilors decided that they couldn’t continue paying the high price associated with these improvements
The project was two years from completion.Alpe du Grand Serre’s closure threatens 200 jobs
“We still have loans to pay as we’ve only been here four years
That’s what is going to happen to us,” the owner of a grocery store in nearby La Morte told The Guardian
low and mid-altitude resorts throughout Europe have been forced to invest in all-season attractions as snowfall becomes less reliable
The Swiss ski area of Skilift Schratten Flühli recently ceased operations citing climate change and financial woes
between 53% and 98% could face snow supply challenges without snowmaking
The percentage range of impacted resorts decreases to 27% and 71% with snowmaking
although an increased reliance on snowmaking poses another challenge: boosted demand for water and electricity
the latter of which can contribute to carbon emissions
I was captivated by the elegant style of Repetto’s ballerinas
they were manufactured near my home in Saint Médard d'Excideuil
visiting the factory was a magical occasion
as it introduced us to the world of artisanal craftsmanship,” Serre said in a press release
adding that she was delighted to see her signature half-moon print reproduced on these iconic shoes.The half-moon
used by Serre since her early days in fashion
looks as though it is embossed on the front of the Lilouh ballerinas

which is being unjustly fought against by the current forces
The Most Reverend Metropolitan of Serres thanked His Beatitude on behalf of the pilgrims for receiving them and for His words of wisdom and experience in the Church of Zion and the All-holy Shrines

The Alpe du Grand Serre ski resort in the French Alps has permanently closed, citing financial difficulties and the impacts of climate change, France3 reports
local authorities voted not to reopen the resort for the upcoming winter season
effectively ending its 85-year run as a popular winter sports destination
will result in the loss of approximately 200 direct and indirect jobs
including 25 ski instructors and their families
The decision will significantly impact the economy of the nearby village of La Morte
which has a population of just 150 residents
director of the French Ski School (ESF) at the resort
expressed his concern about the sudden closure
“It’s a tragedy for the whole valley.” He noted that the ski school works throughout the summer to prepare for winter
highlighting the resort’s year-round impact on local employment
pointed to mounting annual deficits and insufficient funds to complete an ongoing project to transform Alpe du Grand Serre into a year-round destination
Despite investing nearly €3 million since 2021 in diversification efforts
such as developing hiking and biking trails
the community lacked the resources to sustain the project for its final two years
expressed frustration at the lack of government support
“The state is not giving us any concrete support for the future of the resort or a transitional operation.”
Frédérique Laurence runs a restaurant near the resort and added
“We have been left completely in the lurch
The Guardian reports that the closure of Alpe du Grand Serre follows a pattern observed by geographer Pierre-Alexandre Metral of Grenoble University. He noted that an estimated 180 smaller French ski resorts have been forced to close since the 1970s due to various factors, including climate change, poor management, and competition from larger resorts.
Alpe du Grand Serre is smaller than major French resorts like Val d’Isère or Courchevel, but it’s comparable to other mid-sized resorts in the region. The closest major ski resorts are Alpe d’Huez, about 25 miles (40 km) to the east, and Les Deux Alpes, approximately 31 miles (50 km) to the southeast.

This article is part of the Research TopicExtracellular vesicles: emerging roles in the aged and neurodegenerative brainView all 5 articles
Extracellular vesicles (EVs) are secreted by all cells in the CNS
EVs are lipid membrane enclosed particles loaded with various bioactive cargoes reflecting the dynamic activities of cells of origin
the specific role of EVs released by astrocytes is less well understood
partly due to the difficulty in maintaining primary astrocyte cultures in a quiescent state
The aim of this study was to establish a human serum-free astrocyte culture system that maintains primary astrocytes in a quiescent state to study the morphology
and protein cargoes of astrocyte-derived EVs
Serum-free medium with G5 supplement and serum-supplemented medium with 2% FBS were compared for the culture of commercially available human primary fetal astrocytes
Serum-free astrocytes displayed morphologies similar to in vivo astrocytes
higher levels of astrocyte markers compared to astrocytes chronically cultured in FBS
astrocyte and inflammatory markers in serum-free astrocytes were upregulated 24 h after either acute 2% FBS or cytokine exposure
confirming their capacity to become reactive
this suggests that distinct signaling pathways are involved in acute and chronic astrocyte reactivity
chronically serum-cultured astrocyte-derived EVs (ADEVs) were smaller in size compared to serum-free ADEVs and could reactivate serum-free astrocytes
Proteomic analysis identified distinct protein datasets for both types of ADEVs with enrichment of complement and coagulation cascades for chronically serum-cultured astrocyte-derived EVs
offering insights into their roles in the CNS
these results suggest that human primary astrocytes cultured in serum-free medium bear similarities with in vivo quiescent astrocytes and the addition of serum induces multiple morphological and transcriptional changes that are specific to human reactive astrocytes and their ADEVs
more emphasis should be made on using multiple structural
and functional parameters when evaluating ADEVs as biomarkers of astrocyte health
One of the main challenges with neurodegenerative diseases is the length of time it takes to reach a diagnosis, which means that patients cannot access essential support or begin possible treatments until later in the disease progression. Given that astrocyte reactivity typically emerges in the early stages of disease, astrocyte secretions hold promise as a biomarker source for early diagnosis and disease stratification (Escartin et al., 2019)
astrocytes would not be exposed to components of serum in an intact BBB
they should not proliferate under healthy conditions
Serum should be absent from quiescent astrocyte models
yet reliable and reproducible serum-free culture systems for human primary astrocytes are currently unavailable
With a simple serum-free method to culture human primary astrocytes
it would be therefore possible to mimic the in vivo brain microenvironment
as well as offering translational value when evaluating ADEVs as clinical biomarkers of astrocyte reactivity in CNS pathologies
we cultured commercially available human primary astrocytes in an optimized serum-free medium using G5 supplement
and compared their morphological and transcriptional changes to treatments with either 2% FBS or cytokines using immunocytochemistry
ADEVs from both serum and serum-free media were isolated to study their morphology and function
and proteomic analysis was used for characterizing protein cargoes in ADEVs
Human primary astrocytes (SC1800s) were purchased from ScienCell (Cat# SC-1800; distributed by Caltag Medsystems
UK) and stored in liquid nitrogen (−196°C) prior to use
cells were cultured according to the supplier's instructions
astrocytes were cultured in astrocyte medium (ScienCell
1% astrocyte growth serum (AGS) and 1% penicillin/streptomycin solution (P/S) and maintained at 37°C in a humidified atmosphere of 5% CO2
Cells were seeded at a density of 4 × 103 cells/cm2 and passaged every 3–4 days until a maximum of 7 passages
thawed cells from the supplier were initially cultured with serum for a single passage to encourage proliferation before cryopreserving in liquid nitrogen (-196°C) in a solution of 90% FBS (Sigma
UK) and 10% dimethyl sulfoxide (DMSO; Sigma
cells were spun down and thawed in serum-free medium [advanced DMEM (Gibco
UK)] supplemented with 1% G5 supplement (Fisher scientific
UK) with a medium change occurring after 24 h to remove any residual serum from the cryopreservation
cells were seeded at a high density (1.6 × 104 cells/cm2) and sub-culturing was not required
a medium change was performed every 3–4 days
Serum-free astrocytes were treated with either 2% FBS (Caltag, UK) or an inflammatory cytokine cocktail for 24 h. The cytokine cocktail was made up of recombinant human IL-1α at 100 μg/mL, TNFα at 50 μg/mL (both Peprotech, UK) and C1q at 400 ng/mL (Merck, UK), which had previously been shown to induce an inflammatory phenotype in astrocytes (Liddelow et al., 2017)
To harvest sufficient EVs for downstream approaches
at least four collections of medium were completed from serum-free astrocytes (over 2 weeks) and combined for processing
conditioned medium was preserved at −80°C until needed
FBS needed to be removed from the medium before ADEVs were collected to avoid contamination of bovine EVs
cells were seeded as usual in astrocyte medium containing 2% FBS
the cells were carefully washed with PBS before the astrocytes were cultured in astrocyte medium without FBS with the reactive phenotype being maintained
The conditioned medium was then collected after 72 h and stored at −80°C until needed
A minimum of 4x T75 flasks of medium were required to harvest enough EVs for downstream processing
The conditioned medium (~48 mL) was concentrated to 500 μL through centrifugation using 10 kDa MWCO protein concentrators (ThermoFisher scientific
The concentrated 500 μL was then added to a washed qEV original 70 nm column (IZON
Three fractions were collected according to the manufacturer's instructions
the column was washed with both PBS and 0.5 M NaOH solution equal to 2 column volumes
Fractions were frozen at −80°C for longer term storage when required
If a more concentrated EV solution was required for downstream applications
EV fractions were combined and centrifuged using 3 kDa MWCO protein concentrators (Merck
UK) until the desired volume was required (>10-fold concentration)
EV-enriched fractions were fixed in 3% glutaraldehyde and loaded onto copper carbon-coated
200-mesh electron microscopy grids (EM resolutions
Grids were then imaged on the Tecnai Spirit Bio-twin T12 transmission electron microscope (TEM)
Nanoparticle tracking analysis (NTA) was completed on the Zetaview® (Analytik
UK) to measure the size and concentration of the EVs within the EV-enriched fractions
The three EV fractions obtained from SEC were combined before measuring EV concentration using NTA
EVs were diluted to 2.5 – 5.0 × 1011 particles/mL
Serum-free astrocytes were then treated with either 10 μL (2 × 109 particles) or 100 μL (2 × 1010 particles) of purified reactive ADEVs for 24 h
Astrocytes were plated onto 13 mm coverslips at a density of 1 × 105 cells/coverslip for serum-cultured or 2 × 105 cell/coverslip for serum-free astrocytes in a 24-well plate and incubated at 37°C and 5% CO2 for 48 h
permeabilised for 10 min using 0.1% (v/v) Triton X-100 in PBS and then blocked using 1% (w/v) bovine serum albumin (BSA) for 1 h at room temperature
Cells were then labeled overnight with either anti-GFAP (rabbit
UK) was applied for 1 h at room temperature
the coverslips were then mounted onto glass slides using VectorShield mounting medium containing 4,6-diamidino-2-phenylindole (DAPI; VectorShield
UK) and stored at 4°C until imaged
Images were taken using an inverted fluorescent microscope equipped with a Camera Axiocam 305 monodigital (Axio Vert A1
Image analysis was then completed using FIJI software (Image J
The 16830 most expressed genes were used to run the multivariate statistical analysis
To harvest astrocytes for western blotting
Cells were scraped and harvested in fresh PBS
Cells were pelleted by centrifugation at 1,500 × g for 5 min at 4°C
and cells were lysed for 15 min in RIPA lysis buffer (5 M sodium chloride
10% (w/v) SDS) with protease and phosphatase inhibitors at a dilution of 1:1000
Cell debris was pelleted and removed by centrifugation at 16,100 × g for 20 min 4°C
The supernatants were collected to calculate protein concentration using a Pierce BCA assay kit (ThermoFisher Scientific
Samples of 1–10 μg protein were heated for 5 min with 5 μL gel application buffer (0.15 M Tris
then separated using a 5%-20% polyacrylamide gradient SDS-PAGE gel
Proteins were transferred overnight to a nitrocellulose membrane (AmershamTM Protran® western blotting membrane
UK) in Western Transfer Buffer (25 mM Tris
192 mM glycine and 20% (v/v) methanol) at 40 mA and 500 V
The membrane was washed 3x in Tris-buffered saline (TBS; 20mM Tris
pH 7.5) with 0.1% (v/v) Tween (TBS-T) before blocking in 5% milk-TBS-T (5% (w/v) Marvel milk powder in TBS-T) for 1 h at room temperature
The membrane was then incubated with primary antibody diluted in 5% milk-TBS-T overnight at 4°C
Primary antibodies were washed with 3x TBS-T
then a secondary peroxidase rabbit anti-mouse antibody (1:3,000
UK) in blocking buffer was incubated with the membrane for 1 h
a 1:1 mix of Western Lightning Plus ECL reagents (enhanced chemiluminescence
UK) was incubated with the membrane for ~1 min
the membrane was developed on film and fixed
Western-blot densitometry of the film was then performed using FIJI software (Image J
protein extracts were prepared as for immunoblotting
the EV fraction with the most particles (i.e.
EV fraction 2) was heated with 4x Laemmli sample buffer (Bio-Rad
All samples were electrophoresed on a 5%−20% gradient SDS-PAGE gel until the sample had passed through the stacking gel and had entered at least 0.5 cm of the resolving gel
maintaining the proteome in a single gel band
The entire gel was stained with Coomassie dye (Bio-Rad
UK) to highlight the region of the gel to be cut where the protein content for each sample migrated
Samples of serum-free and serum-cultured human astrocytes
and corresponding EV fractions purified from conditioned media
were analyzed independently using LC-MS/MS (Cambridge Center for Proteomics; Cambridge
fragment ion mass tolerance 0.100 Da) and validated with Scaffold 5 (Proteome Software
Carbamidomethyl (+57 on C) was considered a fixed modification
and acetylation (+42 on K/N-terminal M) were considered as variable modifications
our criteria were a minimum of two unique peptides within a run
with peptide threshold set at 95% and protein threshold 99%
giving a mean FDR (false-discovery rate) of ~17% across runs
“presence” and “absence,” across biological repeats
Recognizing the common issue of complexity and variation (or stochasticity) in sampling between LC-MS/MS runs
protein detection in at least 2/3 biological repeats was applied
A negative binomial distribution model was used to calculate significance followed by the Benjamini–Hochberg procedure
with a differential gene screening threshold of log2 (FoldChange) ≥ 1 and padj ≤ 0.05
this contrasted with when the cells were cryopreserved in liquid nitrogen (−196°C) after initial culture in a solution of 90% FBS and 10% DMSO and then revived in serum-free medium with a quiescent phenotype

Measurements were performed after 1 week in culture
While GFAP is well established as an astrocyte marker, these results confirm that quiescent human primary astrocytes showed similarity with in vivo astrocytes, but they do not correlate with increased GFAP expression when astrocytes are chronically cultured in serum, as seen in rodent primary astrocytes (Prah et al., 2019)
suggesting that human primary astrocytes cultured in serum display an inflammatory secretory phenotype

as well as increased ribosome-related pathways in serum-cultured astrocytes
To further test the ability of serum-free astrocytes to become reactive, astrocytes were acutely treated for 24 h with either 2% FBS or cytokines that are secreted by activated neuroinflammatory microglia (i.e., IL-1α, TNFα and C1q) (Liddelow et al., 2017)
The area/perimeter ratio was used to assess morphological changes in both untreated and treated serum-free astrocytes

and ****p < 0.0001
Data represent mean ± SEM and were analyzed using one-way ANOVA followed by either Tukey's or Dunnett's multiple comparison test
Measurements were performed after 24 h exposure to 2% FBS or cytokines
Similar changes in the expression of astrocyte (GFAP, S100β) and inflammatory specific genes (IL-1β, TNFα) were evident in the acute response to 0, 2 and 10% FBS (Supplementary Figure 2). However, there was no dose-dependent effect of FBS concentration, as seen in the morphological analysis (Supplementary Figure 2)
Transcription profiles of astrocyte and inflammatory markers in serum-free astrocytes are different upon acute exposure to either 2% FBS or inflammatory cytokines
(A) Real-time quantitative PCR analysis of GFAP expression showing a significant increase after 2% FBS treatment but not after cytokine treatment (*p < 0.05 vs
(B–E) Real-time quantitative PCR analysis of S100β
showing a trend toward downregulation of these markers in cytokine-treated astrocytes
only S100β expression was significantly downregulated (*p < 0.05 vs
No significant difference was identified after acute FBS treatment
(F–H) Real-time quantitative PCR analysis of IL-1β
showing significant upregulation of inflammatory markers IL-1β and TNF-α in cytokine-treated astrocytes but not in FBS-treated astrocytes (**p < 0.01 vs
Data represent mean ± SEM and were analyzed using one-way ANOVA followed by Dunnett's multiple comparison test
confirming gene expression analysis seen by RT qPCR
These results suggest that acute serum exposure induces morphological changes in astrocytes in a dose-dependent manner
acute exposure to serum seems to activate different signaling pathways in astrocytes compared to chronic serum-culture condition
as astrocyte and inflammatory markers were expressed differently in these conditions
To investigate whether chronic serum culture affects the morphology and protein cargoes of ADEVs
we optimized an isolation procedure to effectively collect a large quantity of ADEVs from serum-free astrocytes
conditioned medium collection was completed four times from a 6-well dish culture until 48 ml of conditioned medium was collected
astrocytes were initially seeded into four T75 flasks with serum-containing medium for 24 h before medium was replaced with astrocyte medium without FBS
Cells were then cultured for 72 h before conditioned medium was collected

(B) Nanoparticle tracking analysis (NTA) showing a significant increase in the median size of serum-free ADEVs compared to serum-cultured ADEVs (**p < 0.01
(C) No difference in particle concentration was identified using NTA between ADEVs (mean = 2 × 1011 particles/mL
(D) Size distribution of ADEVs showing a similar size range of in both serum-free and serum-cultured ADEVs (between 50 and 300 nm diameter)
a shift toward larger EVs was observed in serum-free ADEVs
(E) Representative brightfield images of serum-free astrocytes treated with either 10 μL or 100 μL of serum-cultured ADEVs (2 × 1011 particles/mL)
(F) Heatmap showing that serum-cultured ADEVs dose-dependently altered gene expression of astrocyte and inflammatory cytokine markers in serum-free astrocytes
(G) Real-time qPCR analysis showing a significant increase in GFAP and S100β gene expression after treatment with 100 μL of serum-cultured ADEVs
with an increasing trend also observed in EAAT2 gene expression (**p < 0.01
Data represent mean ± SEM and were analyzed using unpaired t-test (B
C) or one-way ANOVAs followed by Dunnett's multiple comparisons test (G)
This indicates that EVs may transport bioactive molecules capable of propagating a reactive astrocyte phenotype through mechanisms distinct from those involved in both inflammatory processes and UPR
To determine the impact of serum-induced reactivity at the level of the astrocyte whole cell and ADEV proteomes, an exploratory analysis was performed using LC-MS/MS. Based on protein identification in at least 2/3 repeats, significantly more proteins were detected in serum-free cell lysates, with an average of 1,088 proteins detected compared to 680 proteins identified in the serum-cultured cell lysates (Figure 7A

as well as many homeostatic pathways such as insulin secretion and axon guidance
(I) KEGG pathway analysis of serum cultured ADEVs showing disease pathways such as Parkinson's disease and ALS
as well as an enrichment in complement and coagulation cascades
Data represent mean ± SEM and were analyzed using one-way ANOVA followed by Tukey's multiple comparison test
our proteome analyses confirm that primary human astrocytes have a remodeled proteomic phenotype in response to chronic culture with serum
consistent with a shift toward a reactive phenotype
we demonstrate that culturing human primary astrocytes in a serum-free medium recapitulates in vivo phenotypic traits
as evidenced by morphological and transcriptional analysis
Prolonged serum exposure diminishes astrocyte marker expression
while short-term exposure mirrors previous findings on astrocyte reactivity
suggesting distinct signaling pathways for acute and chronic reactivity
We show that chronically serum-cultured astrocytes secrete smaller ADEVs than serum-free astrocytes and can propagate their reactive phenotype to quiescent cells
Each type of ADEVs exhibits unique protein profiles
offering insights into ADEVs as potential biomarkers of CNS pathologies
We therefore speculate that the reduced levels of astrocyte markers in serum condition may be explained by their high proliferative profile
in which cells may invest more in the synthesis of proteins related to cell proliferation instead of specific astrocytic markers
This hypothesis is supported by the observed enlargement of nuclei and elevated levels of IL-1β and IL-10 in serum-cultured astrocytes
characteristic of excessive protein production and an inflammatory secretory phenotype
to validate these molecular profiles effectively
further investigations necessitate functional validation in vivo
we also recommend that more emphasis should be made on multiple structural
to validate ADEVs in biological fluids as biomarkers of CNS pathologies
but this warrants further functional investigation
The concentration of proteins present in serum-cultured medium could potentially trigger astrocyte reactivity to ADEVs and therefore requires further functional investigation
transitioning toward serum-free cultures would eliminate this issue in ADEV studies
this study demonstrates that human primary astrocytes cultured in serum-free medium are akin to in vivo resting astrocytes and maintaining these cells in serum should be avoided as it induces permanent changes that are specific to human reactive astrocytes
These changes are also reflected in their ADEVs suggesting that markers of human primary astrocytes need to be evaluated using multiple molecular and functional parameters before using their ADEVs in functional studies or as predictive biomarkers of astrocyte health

A 34-year-old man was fatally injured on New Year’s Day in Serres
following an altercation in a central area of the city
although local residents reported hearing gunshots
It is believed that at least four individuals were involved in the brawl
on the Macedonian city’s main pedestrian street
while police continue to investigate the incident
Marine Serre continues to challenge fashion storytelling with Heads or Tails
a presentation that reshapes how audiences experience a collection
Instead of staging a traditional runway show or producing a conventional campaign
Serre collaborated with director Tess Lochanski to create a film that occupies space between short cinema and fashion presentation
offering a fresh perspective on her Fall Winter 2025 collection
the designer rejected any clear-cut distinction between formats
choosing instead to construct a world through film that reflects the duality and transformation embedded in the collection
the film pushes beyond the usual boundaries of a seasonal release
the visual piece offers more than documentation
a recurring figure who functions not as a passive presence but as an active symbol
The character channels cinematic influences from directors like David Lynch and the 1996 film Irma Vep
while presenting a contemporary figure of movement
the Ghost reappears as a heroine suspended between dimensions
Marine Serre’s choice to place the Ghost at the core of the visual experience reflects an interest in storytelling that goes beyond clothing
The character operates as a guide and disruptor
drifting through frames with intention and strength
Her presence anchors the tension in the film
The result doesn’t read as a literal adaptation of a show but rather as a reinterpretation of the emotional and conceptual layers within the collection
layering together sonic references that build on the film’s dense visual language
a sample of activist Mario Savio’s speech from Shin Sekai
and a subtle nod to composer Angelo Badalamenti
but creating space for contrast and rhythm
The soundscape moves between haunting and assertive
it intensifies the energy of the Ghost and her movement through the frame
Rather than using models as static visuals
and Manon Dubourdeaux move through the film as if navigating a dream built from equal parts fashion and cinema
Their performances shift the focus from garments alone to the people who carry them
Their roles never settle into one note; instead
they shape and reshape themselves throughout the piece
giving weight to Serre’s interest in transformation
Discover Marine Serre Fall Winter 2025 Collection at Paris Fashion Week
the project doesn’t follow any strict category
Marine Serre uses the Heads or Tails film to move away from routine formats and explore fashion through layered visuals and characters that ask more questions than they answer
crafting an experience that lingers beyond the final frame
beautiful as always but I am not sure she can make it anymore as a solo brand
Time for Marien to get a Creative Director spot in a big house <3

For FW25
Marine Serre staged a runway show at La Monnaie de Paris
yet Serre’s collection challenges the dominance of financial power in fashion
Guests were invited with a custom coin stamped with the moon on one side and Serre’s profile on the other
less a token of commerce than a talisman of independence
Објава коју дели MARINE SERRE (@marineserre_official)
The collection marks a defining moment for Serre
with seven years of building her brand behind her
crafting silhouettes that embody structure and sensuality
and references to femme fatales of the 1950s and 1980s shape the collection’s identity
A midi dress with futuristic shoulders captures the tension between power and desire
while upcycled biker leather is transformed into couture gowns that carry the spirit of rebellion
Accessories mirror this bold energy: the AURORA bag
and a jewelry capsule collection thatcombines tribal elements with classical motifs
These pieces build an image of a woman who is untamed yet composed
but Serre approaches it through reinvention rather than restriction
as vintage watch bracelets are reimagined as jewelry in a venue synonymous with currency
This collection operates like an excavation of the past
uncovering fragments of history and transforming them into wearable statements
The collection unfolds in a palette of white
the latter pulsating with an energy that shifts between passion and power
A carmine velvet tracksuit refines sportswear into something fit for the red carpet
while red mesh and satin channel a hypnotic intensity
The visual language nods to David Lynch’s surreal universe
recalls the grandeur of Chesterfield furniture
while recycled nylon is crafted to resemble leather
The trench coat is deconstructed into layered fragments
Marine Serre creates an experience that challenges certainty
urging us to embrace the unknown with conviction

This expansive space in her image houses her teams
archives and piles of textiles she repurposes for her collections
Entering Marine Serre's expansive premises on Rue d'Aubervilliers in northeastern Paris
it's impossible not to recall the studio where she started out in 2016
her workspace was 150 times smaller – 20 square meters on the fifth floor of a building with no elevator behind Montmartre
a kitchenette and a main room that doubled as a bedroom
After graduating from the Belgian school La Cambre and growing up between Corrèze and Creuse in south-central France
this is where she created her first collections
her first interviews and her first sales to the retail chain Dover Street Market
could one dispute her claim that "luxury is space"
In one of her previous headquarters – a Haussmannian apartment – she recalled
we would always set up camping tables in the middle of the living room
But it soon became too cramped." She spoke with her petite figure
keen eyes and straightforward way of talking mingled with the "Frenglish" typical of those who constantly switch from one language to another
Serre was one of the first to respond to the city of Paris' call for applications to join Métropole 19 – a complex of two five-story rectangular concrete and brick buildings
connected by metal and glass suspension bridges
Architect Jean-Paul Viguier designed the complex in 1988 to accommodate "small
enabling them to remain within the Paris city limits with modern working conditions and low rents," as the architect's agency put it

Faced with a complex financial situation and an initial unfavorable decision by the community council on October 9
SATA Group AEON mobilized alongside local stakeholders to guarantee the resort’s future
This mobilization enabled us to seal an agreement with the Communauté de Communes de la Matheysine for the opening of a season as early as December 21
L’Alpe du Grand Serre aims to attract a renewed clientele
thanks in particular to the innovations promised by SATA Group AEON and an approach geared towards sustainable tourism
With 55 kilometers of varied slopes for all levels
Alpe du Grand Serre stands out for its accessibility and stunning natural scenery
Although modest in size compared to its neighbors
it offers spectacular panoramic views and a warm atmosphere
popular with lovers of tranquillity and nature
the resort attracts families and intermediate skiers
while offering an environment conducive to freeride and learning to ski
The resort also offers a variety of off-piste activities
cross-country skiing and even paragliding for the more adventurous
SATA Group AEON plans to exploit all this potential by turning Alpe du Grand Serre into a laboratory for innovation in sustainable tourism. “The Alpe du Grand Serre will be, within our group, a real laboratory where we can test new activities, attract a diversified clientele, and create a lively mountain destination all year round “ stresses Fabrice Boutet
“We are honored by the trust placed in us by the Communauté de Communes de la Matheysine and its elected representatives to manage this resort
combined with our vision of responsible mountain tourism
will enable us to develop the full potential of this destination
while preserving its authenticity and exceptional environment.“
Despite an initial unfavorable vote at the community council meeting on October 9
SATA Group AEON mobilized alongside local stakeholders
as well as the entire industry – the ESF
various support associations and the French government – in a show of solidarity
A new consultation resulted in an agreement to reopen the resort for 1 year
with the aim of relaunching a public service contract committing the area to the long term
The takeover project was unanimously approved by the Matheysine community council
SATA Group AEON believes in the opportunity to create a new economic model for the future of the mountains through the Alpe du Grand Serre
l’Alpe du Grand Serre could become an example for medium-sized resorts in the French Alps seeking to strike a balance between tourist appeal and respect for the environment
SATA Group AEON’s takeover of Alpe du Grand Serre has prompted mixed reactions from mountain enthusiasts and local players
Some see it as a temporary reprieve for a struggling resort
highlighting the long-term challenges of ensuring the economic viability of small resorts in the face of climate change and changing tourism practices
this project represents an unprecedented opportunity to move the mountains towards an alternative model
more respectful of ecosystems and better anchored in the local economy
driven by a sustainable vision and a willingness to innovate
could well transform the Alpe du Grand Serre into an example for other smaller resorts to follow
demonstrating that it is possible to reconcile tourist appeal with the preservation of mountain territories
resonates in every resort managed by the Group
The importance of the resort for the inhabitants of the Matheysine and surrounding communities is obvious
It generates essential economic activity for many families
accommodation or winter sports-related services sectors
SATA Group AEON’s commitment therefore extends to creating opportunities for local players
and providing season-long support for summer and winter activities
adapted to the modern challenges faced by small ski resorts in France
The Alpe du Grand Serre is scheduled to open on December 21
a symbolic date marking a new beginning for this resort with unique potential
Visitors will be able to explore freshly prepared slopes and discover new facilities
SATA Group AEON intends not only to revive the resort’s activity
but also to demonstrate the viability of its sustainable mountain tourism model
This vision could inspire other resorts of similar size across the French Alps
facing the same economic and environmental challenges
A celebrity chef and her husband kick up their heels with a Western-inspired
The duo were then properly introduced (most definitely matchmaking instincts were at play) at their building’s AGM. A year later, in 2017, they had their first date at Cassis Bistro
DeSousa and Serre had both previously been married and had daughters (DeSousa one
so the idea of getting married again didn’t initially come up
the couple began to discuss the idea of tying the knot
Serre proposed in the same corner seats at Cassis where they had their first date
With the wedding set for the summer of 2024
the couple wanted to incorporate their shared love of Western culture and celebrate the city where they met and fell in love
And what better way to do that than a Stampede wedding
I’ve always loved Stampede and thought it would be a special time to get married and to have our family and friends participate in all things Stampede,” DeSousa says
The ceremony was on the rooftop terrace of DeSousa’s East Village restaurant
and the bride and groom both wore cowboy boots
Rather than a traditional ceremony with a hired officiant and scripted vows
DeSousa and Serre opted for a more personal and familial approach — complete with a special surprise planned by DeSousa
it was award-winning Canadian country singer Paul Brandt
Serre says that moment was the most memorable for him
Brandt played “I Do,” an ideal song to celebrate their union
had Brandt on hand playing the same song while they renewed their vows after 38 years together
The ceremony was officiated by Serre’s best friend
whose words inspired laughter and happy tears
The cheese layers waterfalled down to an eight-foot-long charcuterie board put together by DeSousa’s Charbar team
“It was everything we wanted our wedding to be,” says DeSousa
“From the informal ceremony to one big Stampede party at the end
