April 2023 in “Journal of Investigative Dermatology” This research explored the roles of various T cell types in chronic alopecia areata, finding that increased severity of lesions and hair loss may be linked to decreased lesional Foxp3+ Tregs, with a notable role for IL-17 and Th17 lymphocytes in the pathological process.
July 2024 in “Journal of Investigative Dermatology” Targeting TCR-Vβ2 in cutaneous T cell lymphoma shows promise for safer, more specific treatment.
October 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.
