Chemokine receptors are members of the G protein-coupled receptor superfamily, which together with chemokine ligands form chemokine networks to regulate various cellular functions, immune and physiological processes. These receptors are closely related to cell movement and thus play a vital role in several physiological and pathological processes that require regulation of cell migration. CXCR4, one of the most intensively studied chemokine receptors, is involved in many functions in addition to immune cells recruitment and plays a pivotal role in the pathogenesis of liver disease. Aberrant CXCR4 expression pattern is related to the migration and movement of liver specific cells in liver disease through its cross-talk with a variety of significant cell signaling pathways. An in-depth understanding of CXCR4-mediated signaling pathway and its role in liver disease is critical to identifying potential therapeutic strategies. Current therapeutic strategies for liver disease mainly focus on regulating the key functions of specific cells in the liver, in which the CXCR4 pathway plays a crucial role.

Typically, these viruses are found late in infection. CXCR4 is upregulated during the implantation window in natural and hormone replacement therapy cycles in the endometrium, producing, in presence of a human blastocyst , a surface polarization of the CXCR4 receptors suggesting that this receptor is implicated in the adhesion phase of human implantation. CXCR4's ligand SDF-1 is known to be important in hematopoietic stem cell homing to the bone marrow and in hematopoietic stem cell quiescence. Until recently, SDF-1 and CXCR4 were believed to be a relatively monogamous ligand-receptor pair other chemokines are promiscuous, tending to use several different chemokine receptors. Recent evidence demonstrates ubiquitin is also a natural ligand of CXCR4. It is best known for its intracellular role in targeting ubiquitylated proteins for degradation via the ubiquitin proteasome system. Evidence in numerous animal models suggests ubiquitin is anti-inflammatory immune modulator and endogenous opponent of proinflammatory damage associated molecular pattern molecules. CXCR4 is present in newly generated neurons during embryogenesis and adult life where it plays a role in neuronal guidance. The levels of the receptor decrease as neurons mature. CXCR4 mutant mice have aberrant neuronal distribution. This has been implicated in disorders such as epilepsy. CXCR4 dimerization is dynamic and increases with concentration. Drugs that block the CXCR4 receptor appear to be capable of "mobilizing" hematopoietic stem cells into the bloodstream as peripheral blood stem cells.

Stem Cxcr4 Dev. X4 human immunodeficiency virus Type 1 gp promotes human hepatic stellate cell activation and collagen i expression through interactions with CXCR4, cxcr4. CXCR4 is present in cxcr4 generated neurons during embryogenesis and adult life where it plays a role in neuronal guidance.

Predicted to enable several functions, including chemokine receptor activity; cytoskeletal protein binding activity; and ubiquitin protein ligase binding activity. Involved in myelin maintenance; positive regulation of cold-induced thermogenesis; and positive regulation of oligodendrocyte differentiation. Acts upstream of or within several processes, including circulatory system development; gamete generation; and nervous system development. Located in cell-cell junction; external side of plasma membrane; and growth cone. Is expressed in several structures, including alimentary system; cardiovascular system; embryo mesenchyme; extraembryonic component; and nervous system.

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.
