Out in its final form! Congratulations @sejpaton.bsky.social @jolusolo.bsky.social Alice Cadoret @adelinec.bsky.social @luisa-binder.bsky.social Béatrice Daigle @laura-mb.bsky.social Laurence Dion-Albert @katarzynaadudek.bsky.social @manonlebel5.bsky.social 🥂🧠🤓 www.nature.com/articles/s41...

Environmental enrichment and physical exercise prevent stress-induced social avoidance and blood-brain barrier alterations via Fgf2 - Nature Communications

Chronic stress disrupts the brain vasculature and contributes to mood disorders, but mechanisms of resilience remain unclear. Here, the authors show that enriched environments increase astrocytic Fgf2...

L’exercice et un bon environnement renforceraient l’intégrité de la barrière protectrice du #cerveau Caroline Menard - @cervo-ulaval.bsky.social - Sam Paton - Adeline Collignon - Katarzyna A. Dudek - Manon Lebel

L’exercice et un bon environnement renforceraient l’intégrité de la barrière protectrice du cerveau

Une étude révèle comment l'activité physique et un milieu de vie favorable stimulent la production d'une protéine essentielle à la santé vasculaire, diminuant les effets néfastes du stress et prévenant la dépression

Super excited to share this new paper led by @sejpaton.bsky.social that I briefly mentioned at #ACNP2026 yesterday! 🧪🧠🤓 We tested preventive strategies to protect the brain vasculature #BBB during stress exposure, mix of mouse 🐭 and human data So proud of my team 🤘 www.nature.com/articles/s41...

Hello new followers 🖖 I like looking at the plasma membrane by high res microscopy. Here, you see a platinum replica EM of a fibroblast plasma membrane with clathrin dome (in the center) and caveolae (small invaginations on the side)

Sharing here our most recent preprint and the work of Laurence, PhD student extraordinaire, implicating 🧠 #pericyte in stress responses 🐭 and human depression 😞 www.researchsquare.com/article/rs-5...

Pericytes modulate brain vascular integrity in social stress and depression

Major depressive disorder (MDD) is a leading cause of disease burden worldwide with low therapeutic efficacy. The blood-brain barrier (BBB) is essential to maintain brain homeostasis and regulate drug...
