  • Product Description

    CXCR2 is a 7-TM G-protein coupled receptor that binds to the chemokines GROa, GROb, GROg, IL-8, ENA-78, NAP-2 and GCP-2 (Olson and Ley, 2002). Neutrophils, mast cells and microvascular endothelial cells express CXCR2, and interactions of CXCR2 with its ligands promotes chemotaxis of these cell types (Heidemann et al., 2003; Nilsson et al., 1999; White et al., 1998). Studies with mice lacking CXCR2 indicate that CXCR2 promotes growth of primary tumors and secondary metastases (Keane et al., 2004), and plays an essential role in hyperoxia-induced lung injury (Sue et al., 2004). In addition, cytomegalovirus encodes a CXCR2-binding chemokine, vCXC-1, that promotes neutrophil migration to infected cells (Penfold et al., 1999). The cloned human CXCR2-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant CXCR2 expression on the cell surface and contains high levels of the promiscuous G protein G?15 to couple the receptor to the calcium signaling pathway. Thus, the cell line is an ideal tool for screening for antagonists of interactions between CXCR2 and its ligands.
