Abstract for talk: Vitiligo is an acquired hypomelanotic skin disease results from loss of functional melanocytes from the epidermis leading to white patches. Several theories have been put forward to explain the melanocyte destruction in Vitiligo, but autoimmune hypothesis has been considered as the major one. Antibodies against melanocytes and autoreactive T cells have been found in Vitiligo patients’ skin and blood suggesting that hyperimmune response towards melanocytes led to melanocyte destruction; however, the exact triggering mechanisms are not fully understood. The role of regulatory T cells (Tregs) has been suggested to control the ongoing immune response in healthy individual; however, in Vitiligo patients both, the numbers of Tregs and the suppressive function of Tregs were found to be reduced, particularly in active cases of the disease. Thus, the talk will focus on the deregulation of these Tregs, and possible factors (NFATs, FOXP3) involved in this. Additionally, the therapeutic aspects of Tregs in vitiligo will also be discussed.
