Alopecia Areata But Not Androgenetic Alopecia Is Characterized By A Restricted And Oligoclonal T-Cell Receptor-Repertoire Among Infiltrating Lymphocytes

Alopecia areata (AA) is an autoimmune disorder characterized by a restricted and oligoclonal T-cell receptor-repertoire among infiltrating lymphocytes, while androgenetic alopecia (AGA) is not. This suggests that T cells play a significant role in AA, but not in AGA. The study involved small sample sizes of patients with AA and AGA, and further research is needed to confirm these findings. The restricted T-cell receptor repertoire in AA may lead to the development of targeted therapies for the disease.
