Soluble CTLA-4 regulates immune homeostasis and promotes
Cytotoxic T-lymphocyte-associated antigen -4 (CTLA-4) is a co-inhibitory receptor that restricts T cell activation. CTLA-4 exists as membrane (mCTLA-4) and soluble (sCTLA-4) forms, but the key producers, kinetics, and functions of sCTLA-4 are unclear. Here, we investigated the roles of sCTLA-4 in im …
