Abstract
The distribution of androgen receptor (AR) in human skin was studied by an immunohistochemical method using a polyclonal antibody against the human AR. Skin samples of preputial skin and male and female nongenital skin were examined. The possible correlation of AR location to acne was studied in skin biopsies from skin areas affected or unaffected by acne. In preputial skin, AR was expressed in epidermal cells as well as in fibroblasts, smooth muscle cells, and endothelial cells of blood vessels in the dermal area. AR was found located also in the flat fibroblast-like cells of Pacinian corpuscles. In nongenital skin, AR was also expressed in the basal cells and glandular cells of sebaceous glands, in the outer root sheath of hair follicles, and in eccrine sweat glands. The presence of AR in different cell types in the skin reflects the numerous direct effects androgens may have on this target tissue. The distribution of AR was similar in male and female skin.
