July 2022 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that particulate matter can induce inflammation in human outer root sheath cells, potentially affecting hair growth, through oxidative stress-dependent MAPK and JAK-STAT signaling pathways.

November 2021 in “Signal Transduction and Targeted Therapy” This review discusses the composition, activation, and regulation of the JAK/STAT pathway and highlights its role and inhibitors in various diseases, but reports no new experimental results.
November 2025 in “FEBS Open Bio” In this study, the researchers using Shh-GFP+/- mice found that cyclophosphamide-induced alopecia involves the JAK/STAT1 pathway, where STAT1 binds the Shh gene promoter, decreasing Shh-expressing cells in hair follicles. Treatment with JAK inhibitors helped rescue hair loss, implicating the JAK/STAT1 pathway in this process.
May 2024 in “Archives of dermatological research” This study found that Enz_MoriL, a compound derived from Morus alba L., promotes hair follicle cell proliferation by affecting the Wnt/β-catenin pathway and can counteract an alopecia areata-like condition by suppressing the JAK-STAT signaling in human hair follicle dermal papilla cells.

October 2015 in “Science Advances” This study observed that applying JAK-STAT pathway inhibitors to mouse and human skin led to rapid hair growth by inducing the anagen phase of hair follicles.
