Human immunodeficiency virus (HIV) and related viruses require coreceptors, in addition to CD4, to infect target cells. Some G protein-coupled receptors including CCR5, CXCR4, CCR3, CCR2b and CCR8 in the chemokine receptor family, and four new human molecules GPR15, STRL33, GPR1 and V28 were recently identified as HIV coreceptors. Among them, CXCR4 (fusin, LESTR or HUMSTR) is a principal coreceptor for T-cell tropic strains of HIV-1 fusion and entry of human white blood cells. CXCR4 is also required for the infection by dual-tropic strains of HIV-1 and mediates CD-4 independent infection by HIV-2. The a-chemokine SDF-1 is the ligand for CXCR4 and prevents infection by T-tropic HIV-1. CXCR4 associates with the surface CD4-gp120 complex before HIV enters target cells. CXCR4 messenger RNA levels correlated with HIV-1 permissiveness in diverse human cell types. Antibodies to CXCR4 block HIV-1 and HIV-2 fusion and infection of human target cells. The amino-terminal domain and the second extracellular loop of CXCR4 serve as HIV binding sites.

LAMP2: Protector of the lysosome LAMP2 belongs to the family of membrane glycoproteins who confer selectins with carbohydrate ligands. LAMP2 has been implicated in tumor cell metastasis, as well as overall protection, maintenance, and adhesion of the lysosome. It appears that LAMP2 m... Read full blog post.
CXCR4 Studies on Neural and Stem Cells The CXCR4 (C-X-C chemokine receptor type 4) protein is one member of the G-protein coupled receptor (GPCR1) family. As a multipass membrane protein that is found in several tissues, it is the receptor for the C-X-C chemokine CXCL12/SDF-1. The CXCR4 li... Read full blog post.
Understanding CXCR4 and SDF1 CXCR4 (C-X-C chemokine receptor type 4) is a member of the G-protein coupled receptor (GPCR1) family. It is expressed as a multipass membrane protein in several tissues where it acts as the receptor for the C-X-C chemokine CXCL12/SDF-1. This ligand in... Read full blog post.
