A cross-sectional study of the histopathology and immunology of alopecia areata: Unearthing the role of the Janus kinase–signal transducer and activator of transcription pathway

Alopecia areata is an autoimmune disease that occurs as a result of the loss of the inherent immune privilege of the hair follicle. It has been recently demonstrated that the interferon-γ/interleukin-15 feedback loop that signals via the Janus kinase-signal transducer and activator of transcription pathway is critical to the breakdown of this immune privilege.To evaluate the immunological distribution of CD4+ T-cells, CD8+ T-cells,...
