The Pathogenesis of Alopecia Areata

This study observed that patients with alopecia areata often have a T-cell receptor repertoire in skin lesions that suggests a specific antigen-driven immune response may be important in the disease's pathogenesis.

This review outlines the proposed theories behind the development of alopecia areata, emphasizing the autoimmune process involving lost immune privilege in hair follicles, and stresses the need to pinpoint specific pathogenic mechanisms for potential treatments.

This study found that subcutaneous injection of a CXCL12 neutralizing antibody significantly promoted hair growth in androgenic alopecia and inhibited hair loss in alopecia areata in mouse models, suggesting its potential as a promising treatment for hair loss.

Herpes gestationis is linked to certain antigens, atopic eczema affects T cell populations and may be eased by breastfeeding, higher doses of anti-androgen treatment can improve androgenic alopecia, topical minoxidil increases hair thickness, long-term methotrexate therapy can cause liver fibrosis in psoriasis patients, and Lichen Sclerosus et Atrophicus patients aren't at higher risk for autoimmune disorders.

In this study, the alcoholic extract DN106212 from Centipeda minima was shown to be more effective in promoting hair growth in C57BL/6 mice compared to dimethyl sulfoxide and tofacitinib, suggesting its potential as a natural hair growth agent.
