CXCR4 is one of several chemokine co-receptors that HIV can use to infect CD4+ T cells. HIV isolates that use CXCR4 are traditionally known as T-cell tropic isolates. Typically, these viruses are found late in infection.

Among chemokine receptors, CXCR4 is the most widely expressed, and is involved in numerous physiological and pathological conditions. CXCR4 is expressed by most cells, including hematopoietic and endothelial cells (ECs), neurons and stem cells (embryonic and adult).

2024年12月24日 · CXCR4 (C-X-C Motif Chemokine Receptor 4) is a Protein Coding gene. Diseases associated with CXCR4 include Whim Syndrome 1 and Macroglobulinemia, Waldenstrom 1. Among its related pathways are Class A/1 (Rhodopsin-like receptors) and Nervous system development.

The chemokine receptor 4 (CXCR4) and 7 (CXCR7) are G-protein-coupled receptors (GPCRs) activated through their shared ligand CXCL12 in multiple human cancers. They play a key role in the tumor/tumor microenvironment (TME) promoting tumor ...

2024年9月23日 · We show that CXCR4 adopts distinct subunit conformations in trimeric and tetrameric assemblies, highlighting how oligomerization could allosterically regulate chemokine receptor function.

2020年8月27日 · The CXCR4 receptor upon binding its ligands triggers multiple signaling pathways that orchestrate cell migration, hematopoiesis and cell homing, and retention in the bone marrow. However, CXCR4 also directly controls cell proliferation of non-hematopoietic cells.

2015年1月22日 · CXCR4 is a rare CXC receptor that possesses a sulfotyrosine in the proximal N terminus (position C-7) (fig. S4C), which may explain its ability to engage a CC chemokine (vMIP-II) via its basic N or β 2-β 3 loops.

The CXCR4 gene provides instructions for making a receptor protein that spans the outer membrane of cells, specifically white blood cells and cells in the brain and spinal cord (central nervous system). Learn about this gene and related health conditions.

CXCR4 promotes migration, invasion, and epithelial-mesenchymal transition of papillary thyroid carcinoma by activating STAT3 signaling pathway. Comprehensive Analysis of CXCR4, JUNB, and PD-L1 Expression in Circulating Tumor Cells (CTCs) from Prostate Cancer Patients.

CXCR4 (CXC chemokine receptor type 4), a member of the G protein–coupled receptor superfamily, plays a role in cell migration and functions as a coreceptor for HIV entry. Molecular therapeutics targeting CXCR4 have been under intensive investigation. To date, only two small-molecule antagonist drugs targeting CXCR4, plerixafor (AMD3100) and ...
