July 2024 in “Journal of Investigative Dermatology” The Fas/FasL pathway may play a role in alopecia areata.
April 2019 in “Journal of Investigative Dermatology” This study observed that simvastatin promoted hair regrowth in a mouse model of alopecia areata by reducing inflammatory markers and T cell proliferation, partly through disruption of isoprenoid metabolite production.
November 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, researchers used a mouse model of alopecia areata to demonstrate that both ruxolitinib and baricitinib, oral JAK inhibitors, reduced hair loss, CD8+ cell infiltration, and expression of disease-related markers, with baricitinib showing greater effectiveness.
July 2024 in “Journal of Investigative Dermatology” IL-27 may help prevent hair loss in alopecia areata by promoting immunosuppressive T cells.
