CD184-PE

A07409


CD184 (also known as CXCR4, or Fusin) is a seven-transmembrane domain G protein-coupled surface receptor. CD184 (CXCR4) natural ligand is the stromal cell-derived factor-1 (SDF-1), a C-X-C chemokine (the nomenclature specifies that this chemokine has a single amino acid between the first two cysteines of the characteristic four cysteine motif), which is strongly chemotactic for monocytes and lymphocytes. But CD184 (CXCR4) has also initially been described as the human immunodeficiency virus-1 (HIV-1) entry co-receptor, associated with the surface CD4-gp120 complex before HIV-1 enters target cells. It also acts as an alternative receptor for some isolates of HIV-2. The SDF-1 / CXCR4 pair may also play a role in the development of the nervous system. Unlike other chemokine receptors, the cellular distribution of CD184 (CXCR4) is nearly ubiquitous; it is expressed on a variety of CD4+ and CD4– cells in the immune system and the central nervous system. In blood, CD184 (CXCR4) is highly expressed on neutrophils, monocytes, dendritic cells, NK cells, B cells, and T cells, as well as on platelets. CD184 (CXCR4) exhibits a rapid (30 seconds) up-regulation upon activation of lymphocytes, followed by internalization (within 2 minutes). Accordingly, CD184 (CXCR4) is detected in large amounts in intracellular stores within leucocytes. Absent from eosinophils and basophils in fresh whole blood, CD184 (CXCR4) is inducible ex vivo on eosinophils by glucocorticoids, and on basophils by SDF-1. As a GPCR, CXCR4 binding of SDF-1 triggers certain signaling pathways such as ras, and PI3 kinase. One downstream effect of SDF-1 / CXCR4 interaction is the activation of transcription factors such as AP-1 and chemokine regulated genes. JAK / STAT pathways also play a role in SDF-1/CXCR4 signaling.
