Female patients with androgenetic alopecia: immunohistochemical picture of scalp biopsies
The aim of the research. To expand the knowledge about immunohistochemical changes in female patients with androgenetic alopecia (AGA) focusing on non-androgenic co-factors of pathogenesis of the disease, as this may serve as a basis for improving therapeutic regimens.
Materials and methods. Scalp biopsies of female patients with androgenetic alopecia were examined by immunohistochemical method. The study included two groups: the main group of 30 female patients aged 22 to 40 years, average age 32,13±5,03 years, and the control group that included 20 skin samples from women aged 25–40 years (average age 34,75±4,19 years) who underwent autopsies.
Results. It was found that AGA in women is characterized by a number of immunomorphological manifestations: the inflammatory infiltrate that consists of immunocompetent T-lymphocytes CD3+, CD4+ and CD8+, macrophages (CD68+); imbalance of growth polypeptides VEGF, TGF-β1, EGFR; accumulation of oxidative stress enzymes eNOS and iNOS; accumulation of pathological fraction of Collagen IV.
Conclusions. The data obtained by this study helps to improve the concept of morphogenesis of AGA, and also can become a base to improve the standards of treatment of the disease. The pathological triade “oxidative stress-microinflammation- fibrosis” should be considered as a possible treatment target, as well as the imbalance of growth peptides.
