Several rodent models, particularly the C3H/HeJ mouse and DEBR rat, were used to study alopecia areata (AA), an inflammatory hair loss disease with suspected autoimmune elements. Research methods included flow cytometry, microarray characterization, cell manipulation, lymph node cell transfer, and transgenic knockout mice. Findings indicated that AA development relied on genetic susceptibility, with major and minor genes influencing disease severity, and epigenetic factors affecting onset and persistence. AA in rodents was primarily Th1 cell mediated, involving breakdown of hair follicle immune privilege, antigen presentation, autoreactive lymphocytes, and regulatory cell deficiencies. Rodent models helped evaluate current AA treatments and develop new therapies, suggesting that further understanding could lead to improved interventions.
