December 2005 in “Journal of Investigative Dermatology” This study found significant associations between certain MICA variants and haplotypes with alopecia areata, suggesting MICA as a potential candidate gene linked to the disease's susceptibility and severity.

March 2025 in “Pediatric Dermatology” This study found that alopecia areata is linked to genetic factors, specifically HLA haplotypes on chromosome 6, and involves immune privilege collapse at hair follicles which is mediated by the JAK-STAT pathway and pro-inflammatory cytokines like IFN-γ.

January 2025 in “Frontiers in Immunology” In this study, researchers found that cytokine dysregulation linked to genetic background is present in both patients and healthy but genetically related individuals in two autoimmune skin diseases, Pemphigus vulgaris and Alopecia areata, suggesting that protective immune mechanisms may prevent disease manifestation in predisposed individuals.

January 2011 in “Annals of Dermatology” This review discusses the reclassification of pregnancy-related skin diseases and provides a management algorithm but reports no new clinical findings.
