[Advances in the Role of Low-Dose Interleukin-2 in Immune-Mediated Dermatosis].

Immune-mediated dermatoses are the skin diseases caused by the breakdown of immune tolerance,including lupus erythematosus and dermatomyositis.The imbalance between regulatory T cells (Tregs) and effector T cells (Teffs) plays a key role in the pathogenesis of these diseases.Low-dose interleukin-2 can preferentially activate Tregs and reverse the imbalance between Tregs and Teffs to recover the immune tolerance,which has attracted attention in the treatment of immune-mediated dermatoses.This review summarizes the research progress in the immunomodulatory mechanism and clinical application of low-dose interleukin-2 in immune-mediated dermatoses,providing a new idea for the clinical treatment of these diseases.
