November 2024 in “EMBO Molecular Medicine” In this study, researchers found that disrupting EGFR signaling in mice led to increased inflammation and hair follicle damage but that inhibiting the JAK-STAT1 pathway could restore hair growth and skin function.
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.
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.
November 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that in mice, hyper-activated JAK-STAT1 signaling due to EGFR inhibitor treatment leads to scarring alopecia, but JAK1/2 inhibition can restore hair follicle immune privilege and promote new hair growth.
May 2026 in “International Journal of Molecular Sciences” This review highlights emerging evidence that chemotherapy-induced alopecia may be driven by immune mechanisms similar to alopecia areata, involving hair follicle immune privilege collapse, and evaluates Janus kinase inhibitors as potential treatments, while cautioning about their immunosuppressive risks in cancer patients.
