chemokine receptor

(redirected from Chemokine receptors)

chemokine receptor

Abbreviation: CCR
Any of several protein receptors for chemokines that spans the cell membrane and links to intracellular G proteins. The cell-to-cell signaling and regulating effects of chemokines, e.g., on inflammation or hematopoiesis, are mediated through chemokine receptors, which can be blocked with specific antagonist drugs. CCR5 and CXCR4 are chemokine receptors that are also receptors for HIV. The virus uses these receptors to gain entry into T cells, macrophages, and other CD4+ cells.

The effective immune response to HCV infection requires efficient recruitment and activation of inflammatory cells (monocytes and T lymphocytes) to the infected liver in which chemokines and chemokine receptors are involved and play important roles in the pathogenesis of chronic hepatitis C (8,9).
HSCs are capable of expressing different chemokine receptors; such as CXC chemokine receptor (CXCR) 3; C-C chemokine receptor (CCR) 5; CCR7; and ligands, including chemokine ligand (CCL) 2, CCL3, CCL5, CXC chemokine ligand (CXCL) 1, CXCL8, CXCL9, and CXCL10.

Because these chemokine receptors are expressed preferentially on lymphocytes, only lymphocytes exhibit firm adhesion via activated LFA-1, which then binds to the immunoglobulin-like-domain-containing adhesion molecules, ICAM-1 and ICAM-2 on the surface of HEV ECs.
These similarities between results obtained from WGCNA and those from DAVID bioinformatics and PANTHER database analyses highlight the result that tDCS induces change in signaling pathways, especially involving cytokine and chemokine receptors, which in turn have important effects on how neural cells are communicating, metabolizing, and structuring.
