April 2021 in “JCI insight” In this study, selective inhibition of JAK3 signaling effectively prevented and reversed alopecia areata in a mouse model, while JAK2 inhibitors did not restore hair growth.
April 2024 in “Journal of translational medicine” In this study, the researchers identified MJ04, a selective JAK3 inhibitor, as a promising candidate for promoting hair growth, demonstrating efficacy in both animal models and human hair follicle assays with a favorable safety and pharmacokinetic profile.
