November 2022 in “The journal of investigative dermatology/Journal of investigative dermatology” This study reported that IL-15 promotes human hair growth and protects hair follicle immune privilege, potentially stabilizing alopecia areata treatment outcomes when selectively stimulating IL-15Rα signaling.
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.

November 2014 in “The journal of investigative dermatology/Journal of investigative dermatology” This case report observed that oral tofacitinib treatment resolved both alopecia universalis and plaque psoriasis in a patient, possibly by targeting shared inflammatory pathways.
March 2026 in “Skin Appendage Disorders” This study identified CD28, GZMB, and CD1C as key immune regulators in alopecia areata, highlighting CD28 as a potential therapeutic target with a promising safety profile, using a proteome-anchored multi-omics approach to uncover actionable targets for this autoimmune hair-loss disorder.
