November 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, researchers found that ex vivo and in vivo administration of the TYK2 inhibitor BMS-986202 prevented immune privilege collapse and promoted hair regrowth in models of alopecia areata, suggesting this approach may offer a new therapeutic avenue deserving of clinical investigation.
November 2022 in “The journal of investigative dermatology/Journal of investigative dermatology” This study observes that TYK2 inhibition with BMS-986202 may extend hair follicle growth phases and decrease inflammatory cell markers in alopecia areata, suggesting potential for clinical application.
July 2022 in “Journal of Investigative Dermatology” This study found that a TYK2 inhibitor, BMS-986202, may restore immune privilege in hair follicles and promote hair regrowth in a humanized alopecia areata mouse model by inhibiting IL-12-mediated signaling.
October 2021 in “Journal of Investigative Dermatology” This study found that interleukin-12 signals play a role in hair follicle immune privilege collapse in ex vivo alopecia areata models, and a TYK2 inhibitor may help prevent or reverse this process.
