- NCIT_C39043 NCIT_P325 "CXCR4 is a chemokine receptor in the GPCR gene family, and is expressed by cells in the immune system and the central nervous system. In response to binding its ligand SDF-1 (stromal cell-derived factor-1), CXCR4 triggers the migration and recruitment of immune cells. This ligand-receptor pair may also play a role in development of the nervous system. In addition to acting as a chemokine receptor, CXCR4 is a co-receptor for entry of HIV into T cells and ligands of CXCR4, including SDF-1, may help to block HIV infection. Early in the infection of an individual, HIV viruses often are tropic for the CCR5 coreceptor that provides for macrophage entry, then later in infection are tropic for CXCR4 and T cell entry. Viruses that are tropic for CXCR4 are generally syncytium forming, causing T cells to aggregate and be destroyed at a rapid rate. CXCR4 induces downstream signaling by several different pathways. As a GPCR, CXCR4 binding of SDF-1 activates G-protein mediated signaling, including downstream pathways such as ras, and PI3 kinase. PI3 kinase activated by SDF-1 and CXCR4 plays a role in lymphocyte chemotaxis in response to these signals. One endpoint of CXCR4 signaling is the activation of transcription factors such as AP-1 and chemokine regulated genes. JAK/STAT signaling pathways also appear to play a role in SDF-1/CXCR4 signaling. Delineation of the signaling mechanisms utilized by CXCR4 may assist in determining the role of CXCR4 in HIV infection and in the immune response.
