Article Title: C-type lectin OCILRP2/Clr-g and its ligand NKRP1f costimulate T cell proliferation and IL-2 production
Abstract: We are reporting the identification of a novel C-type lectin receptor-ligand pair that is involved in T cell costimulation. The receptor, OCILRP2/Clr-g, is rapidly induced following T cell activation and maintained at a substantial level of up to 72 h. The ligand, NKRP1f, is predominantly expressed on dendritic cells (DC). The soluble OCILRP2-Ig blocking protein significantly suppresses specific antigen-stimulated T cell proliferation as well as IL-2 secretion both in vitro and in vivo; conversely, NKRP1f-expressing antigen presenting cells (APC) enhance B7.1/CD28-mediated costimulation for T cell proliferation through interaction with OCILRP2/Clr-g. Our studies reveal a unique functional interaction between two C-type lectins, OCILRP2/Clr-g and NKRP1f, during APC-mediated T cell costimulation and suggest a role for C-type lectins in maintaining T cell response or memory in vivo. © 2005 Elsevier Inc.
