Serarslan G. et al., in their publication, indicate that patients with alopecia areata of the scalp have a higher serum concentration of leptin and adiponectin, and it is suggested that these adipokines may be linked to the development of the disease [12], while the secretion of leptin is dependent on the body mass index and the amount of fat tissue [12]. The gene discussed is LEP; the disease is alopecia areata.
