PG - 109153 LID - S1521-6616(22)00234-0 [pii] LID - 10.1016/j.clim.2022.109153 [doi] AB - Systemic lupus erythematosus (SLE) is a typical autoimmune disease characterized by multiorgan involvement and marked variability in clinical presentation. SLE pathogenesis includes regulatory T cell dysfunction and antinuclear antibody production. Mammalian target of rapamycin (mTOR), a serine/threonine kinase in the phosphoinositide 3-kinase (PI3K)-related kinase family, is a therapeutic target for autoimmune diseases such as SLE. Rapamycin, an inhibitor of the mTOR signaling pathway, is a macrolide antibiotic with potent immunosuppressive, antiproliferative and antifibrotic effects. Recently, an increasing number of studies have investigated the role of mTOR in regulatory T (Treg) cells and its impact on SLE pathogenesis. This review aims to systematically summarize the role of the mTOR signaling pathway in SLE pathogenesis, Treg cell dysfunction and SLE treatment. CI - Copyright (c) 2022 Elsevier Inc.
