The concentrations of ATP, IL-6, and IL-10 were measured in extracts of plucked hair follicles from healthy volunteers (normal values) and patients with androgenetic alopecia and then, ATP, IL-6, and IL-10 content was calculated for each follicle. The resulting values were directly proportional to hair follicle length, except for IL-6. The concentration of extracted ATP correlated with lactate dehydrogenase activity indicating cell damage. In patients with androgenetic alopecia, IL-10 content exceeded the normal values in follicles with a length <1 mm and ATP content surpassed the normal in follicles >2 mm long. The content of IL-6 and IL-10 measured by ELISA was comparable with results of mRNA expression assayed by RT-PCR, which attested to moderate level of gene expression. The content of ATP and IL- 10, but not IL-6 depended on the length of plucked hair follicle and on pathogenetic factors affecting hair growth.
