Human MST1 deficiency causes a novel primary immunodeficiency syndrome accompanied by autoimmune manifestations. However, the mechanism by which Mst1 controls immune regulation is unknown. In this article, we report that Mst1 regulates Foxp3 expression and Treg development\/function and inhibits autoimmunity through modulating Foxo1 and Foxo3 (Foxo1\/3) stability. We have found that Mst1 deficiency impairs Foxp3 expression and Treg development and function in mice. Mechanistic studies reveal that Mst1 enhances Foxo1\/3 stability directly by phosphorylating Foxo1\/3 and indirectly by attenuating TCR-induced Akt activation in peripheral T cells. Our studies have also shown that Mst1 deficiency does not affect Foxo1\/3 cellular localization in CD4 T cells. In addition, we show that Mst1\u2212\/\u2212 mice are prone to autoimmune disease, and mutant phenotypes, such as overactivation of naive T cells, splenomegaly, and autoimmune pathological changes, are suppressed in Mst1\u2212\/\u2212 bone marrow chimera by cotransplanted wt Tregs. Finally, we demonstrate that Mst1 and Mst2 play a partially redundant role in Treg development and autoimmunity. Our findings not only identify Mst kinases as the long-searched-for factors that simultaneously activate Foxo1\/3 and inhibit TCR-stimulated Akt downstream of TCR signaling to promote Foxp3 expression and Treg development, but also shed new light on understanding and designing better therapeutic strategies for MST1 deficiency\u2013mediated human immunodeficiency syndrome.<\/jats:p>","DOI":"10.4049\/jimmunol.1301060","type":"journal-article","created":{"date-parts":[[2014,1,23]],"date-time":"2014-01-23T04:55:34Z","timestamp":1390452934000},"page":"1525-1535","source":"Crossref","is-referenced-by-count":134,"title":["<i>Mst1\/Mst2<\/i>
