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 2024 in “EMBO Molecular Medicine” This study used a mouse model to enhance understanding of alopecia pathogenesis and suggested a therapeutic strategy for managing inflammation in EGFR-inhibitor therapy-induced folliculitis and cicatricial alopecia.
April 2026 in “Frontiers in Immunology” This study concluded that the CXCL12–CXCR4 signaling pathway significantly contributes to hair loss in androgenetic alopecia and alopecia areata by promoting inflammation and fibrosis, whereas inhibiting this pathway can restore hair growth and follicle health.
September 2017 in “Journal of Investigative Dermatology” This study suggests that sweat glands may have an immune privilege similar to hair follicles, and disruptions in this could contribute to autoimmune skin diseases.

January 2024 in “Annals of Dermatology” Winter-onset alopecia areata patients are more likely to regrow hair within a year compared to spring-onset patients.
April 2021 in “Journal of Investigative Dermatology” This study suggests that rather than inhibiting IL-15, selectively stimulating IL-15Ra-mediated signaling could be beneficial for managing alopecia areata and possibly other inflammatory hair loss conditions, as IL-15 promoted hair growth and maintained immune privilege in human hair follicles.
