WebNov 29, 2012 · Recent studies have implicated vitamins A and D in the control of T-cell homing to the small intestine and skin tissue. 11,12 In brief, vitamin A was shown to play a crucial role in the induction of the “gut-homing” receptors CCR9 and α4β7 in murine T cells, 13 and the production of active vitamin A metabolites was shown to be a feature of … WebBoth immunoblot and confocal microscopy analyses demonstrated that CCR7 was predominantly expressed on the cell surface of M1 but in the cytosol of M2 macrophages before ligand stimulation. As a result, CCL19 or CCL21 induced activation of both MEK1-ERK1/2 and PI3K-AKT cascades in M1 but not in M2 macrophages.

WebJan 4, 2016 · CCR7 and its ligands CCL19 and CCL21 control homing of T cells and dendritic cells to areas of the lymph nodes where T cell priming and the initiation of the adaptive immune response occur. Moreover, … WebThe CCR7 receptor, a member of the C-C chemokine receptor family, is a G protein-coupled receptor (GPCR). It was identified as a gene induced by the Epstein-Barr virus (EBV). CCR7 is expressed in various lymphoid tissues including B and T lymphocytes and mature dendritic cells (DC).
WebApr 8, 2004 · Abstract. Purpose: The chemokine CC-ligand 21/secondary lymphoid tissue chemokine (CCL21/SLC) regulates the homing of naïve T cells and dendritic cells that express CC-chemokine receptor 7 (CCR7) from distant sites to lymphoid tissue such as lymph nodes. We hypothesized that CCL21/SLC regulates the migration of CCR7 … WebFeb 28, 2024 · The chemokine receptor CCR7 has been identified as one of the key regulators of immune cell entry into LNs.
