title: [Lymphocyte subpopulations in alopecia areata].
abstract: Subsets of peripheral blood lymphocytes were studied in 19 patients with alopecia areata. The results shows: a decreased Tm/Tg ratio, decreased number of OKT4+ cells, increased OKT8+ cells, decreased OKT4+/OKT8+ cell ratio. Total lymphocytes, T cells, Tm cells, Tg cells, T DR+ cells and B lymphocytes were normal. The results are similar to those founded in autoimmune diseases and suggest the existence of an immunopathogenic mechanism in these disease.
