CXCR3 Antibodies

Target Information

CD183, also known as CXCR3, is a seven-transmembrane G protein-coupled chemokine receptor that binds CXCL9 (Mig), CXCL10 (IP-10), and CXCL11 (I-TAC), which are part of the CXC chemokine subfamily. CD183 plays a crucial role in leukocyte traffic, influencing integrin activation, cytoskeletal changes, and chemotactic migration. It is expressed on NK cells, subsets of T lymphocytes, regulatory T cells (Tregs), and is preferentially found on Th1-polarized cells. CD183 is prominently expressed in effector/memory T cells and T cells in inflamed tissues, contributing to CD4 T cell responses to grafts, as evidenced by compromised allograft rejection in CXCR3 knockout mice. Chemokine binding induces rapid, short-lived cellular responses due to receptor internalization, with responsiveness restored after receptor recycling. Inhibition by Bordetella pertussis toxin suggests coupling with Gi subclass G proteins. The production of IP-10, Mig, and I-TAC in inflammatory lesions indicates CD183 role in recruiting inflammatory cells, making it a target for developing antagonists to treat inflammatory diseases. Multiple transcript variants encoding different isoforms of CD183 have been identified.
