It not only controls appetite through leptin receptors in the hypothalamus, it also regulates immunity. In the current study, we produced leptin-deficient MRL\/Mp-Faslpr mice to investigate the potential role of leptin in autoimmunity. C57BL\/6J-ob\/ob mice were backcrossed with MRL\/Mp-Faslpr mice, which develop human systemic lupus erythematosus (SLE)-like lesions. The effects of leptin deficiency on various SLE-like manifestations were investigated in MRL\/Mp-Faslpr mice. The regulatory T cell population in the spleen was analyzed by flow cytometry, and the effects of leptin on regulatory T cells and Th17 cells were evaluated in vitro. Compared with leptin-producing MRL\/Mp-Faslpr mice, leptin-deficient MRL\/Mp-Faslpr mice showed less marked splenomegaly and a particularly low population of CD3+CD4\u2212CD8\u2212B220+ T cells (lpr cells). Their serum concentrations of Abs to dsDNA were lower, and renal histological changes at age 20 wk were ameliorated. Regulatory T cells were increased in the spleens of leptin-deficient MRL\/Mp-Faslpr mice. Leptin suppressed regulatory T cells and enhanced Th17 cells in vitro. In conclusion, blockade of leptin signaling may be of therapeutic benefit in patients with SLE and other autoimmune diseases.<\/jats:p>","DOI":"10.4049\/jimmunol.1301685","type":"journal-article","created":{"date-parts":[[2014,1,4]],"date-time":"2014-01-04T03:26:41Z","timestamp":1388806001000},"page":"979-984","source":"Crossref","is-referenced-by-count":47,"title":["Deficient
