A skin colonizer disrupts inflammatory and humoral immune defenses in hidradenitis suppurativa - EMBO Molecular Medicine Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease associated with a polybacterial dysbiosis devoid of a known pathogen. Here, we report that HS patients mount IgA and IgG responses ...

Model describing how commensal microbes drive the accumulation of Monocytes to the neonatal skin. Depleting these monocytes in the neonatal window leads to an IL-1 dependent aberrant release of IL-17 from cutaneous T cells later in life. This renders mice more susceptible to psoriasiform inflammation in adulthood.

Excited, grateful, and proud to share our latest research published in Immunity. None of this would have been possible without contributions from all our co-authors, across institutions. Shoutout to @scharschmidtlab.bsky.social for her unwavering support over the years! www.cell.com/immunity/ful...

Psoriasis: Unraveling the Causes of Chronic Itching In psoriasis and other inflammatory skin diseases, chronic itching or pruritus is a particularly distressing symptom for patients which remains difficult to treat today. Scientists at the Institut Pas...

🧠🧬 Psoriasis: Unraveling the Causes of Chronic Itching

@belkaidlab.bsky.social and Institut Pasteur researchers show that an excessive immune response to skin microbes activates the IL‑17A pathway in nerves, leading to chronic itch and nerve regrowth.

Busy experiment day in the Belkaid lab today - lots happening!

Congratulations to @belkaidlab.bsky.social alumni, Jérémie @jdllkss.bsky.social, for a brilliant PhD defense! 🎉

Reframing IL-27: a central regulator of CD8+ T cell immunity Interleukin-27 (IL-27), a member of the IL-12 cytokine family, was long viewed primarily as a regulator of CD4+ T cell immunity. Subsequent studies revealed that IL-27 also directly modulates CD8+ T c...

“Women in Skin Science” prize by Almirall & #ESDR to Prof. Yasmine Belkaid

'Women in science' round table at the ESDR 2025

Thrilled to share that my mentor Prof. Yasmine Belkaid received the “Women in Skin Science” prize by Almirall & #ESDR 🌟👏. At the round table, she rightly reminded us: “Life is too short to be boring, take risks.” 💡💪 #WomenInScience #Skin @esdrorg.bsky.social @belkaidlab.bsky.social

Childhood eczema linked to mother’s stress during pregnancy The causes of early-life eczema have been unclear, but evidence indicates that changes to fetal immune cells and sensory neurons during pregnancy play a key part.
