Ca y est, notre projet «Équipe labellisée FRM» démarre ! Objectif : restaurer l'immunosurveillance des cellules sénescentes pour prévenir les maladies liées à l'âge. Très reconnaissant à la @FRM_officiel, à ses donateurs et à son comité scientifique pour leur confiance ! @univcotedazur.bsky.social

Proud to share our latest preprint! We demonstrate that targeting the immune checkpoint GD3 with a short mid-life treatment leads to long-lasting health benefits (>1 year after treatment cessation). Kudos to @irynamoskalevska.bsky.social, to the ISAC team and collaborators @ircan.bsky.social

Targeting the senescence-associated immune checkpoint GD3 ganglioside extends healthspan and blunt age-related diseases with sex-specific benefits.
The accumulation and impact of senescent cells in age-related diseases are increasingly characterized. However, the mechanisms underlying their accumulation and their causative role in age-associated ...

#RésultatScientifique🔎 | Vieillissement : un bouclier levé ? @juliencherfils.bsky.social et ses collaborateurs ont découvert comment un glycolipide protège les cellules sénescentes du système immunitaire. En le ciblant, ils parviennent à réduire les effets du vieillissement chez la souris ! 🧪

GD3 ganglioside checkpoints in immune surveillance of senescent cells - Nature Aging
Iltis, Moskalevska and colleagues investigate how the innate immune system regulates the age-related accumulation of senescent cells. They show that upregulation of the GD3 ganglioside-based immune ch...

This paper, coupled with the Perspective from Neuron, really indicates that our understanding of the immune system on an aging brain could well be entering a new phase - one with lots of great data rather than mainly conjecture. www.cell.com/neuron/abstr...

Chronological versus immunological aging: Immune rejuvenation to arrest cognitive decline
Basurco and Abellanas et al. discuss how immune system aging negatively impacts the brain and propose immune rejuvenation as a strategy to combat cognitive decline and sustain lifelong brain health.

4/7 By targeting GD3 with immunotherapy in mice, we demonstrated reduced fibrosis (lung, liver) and osteoporosis. These findings open exciting therapeutic avenues for combating aging and its associated diseases.

3/7 SICs are a novel mechanism that allows senescent cells to escape immune clearance by NK cells. GD3 acts as an "invisibility cloak," enabling these cells to persist, to be “tolerated” by immune system and contribute to age-related diseases.
