Downregulation of miR-3940-5p promotes T-cell activity by targeting the cytokine receptor IL–2R gamma on human cutaneous T-cell lines

Vitiligo is a common established depigmentation skin disease characterized by the presence of activated T lymphocytes anti melanocytes within the skin. T-cell immunity mainly mediates the destruction of melanocytes and is one of the main mechanisms involved in the pathogenesis of non-segmental vitiligo. Our previous study had identified several differentially expressed miRNAs and found that the expression of miR-3940-5p was downregulated in vitiligo patients. According to the research findings, we hypothesized that the novel miRNA plays a potential role on human cutaneous T lymphocytes in the action mechanism of immune imbalance in vitiligo.
