Abstract

Summary We then performed ligand-based receptor capture with VISTA–Fc chimeric protein and human CD4 + Tcells at acidic pH 19 . PSGL-1 was one of few proteins that were enriched relative to controls (Fig.3a). In addition to its well-characterized role facilitating adhesion interactions between leukocytes, platelets and endothelial cells 20,21 , PSGL-1 has been identified as a negative regulator of T cell responses in contexts of chronic viral infection, cancer, and some autoimmune diseases 22–28 .
