The 4B12 monoclonal antibody reacts with mouse CCR7, also known as EBI-1 and CD197. For optimal visualization of CCR7 expression on different cell types it is necessary to use multi-color staining to discriminate different cell subsets (please see Technical Data Sheets for recommended concentration for individual formats). To address specificity, the staining profile of 4B12 has been compared to a polyclonal antibody generated against a CCR7 peptide (Bjorkdahl et al). This analysis confirms that the polyclonal antibody and 4B12 stain similar populations of cells. Furthermore, 4B12 stains mouse CCR7-GFP fusion protein-transfected RBL cells (see data in cat. 14-1971).
CCR7 is a chemokine receptor for the chemokines CCL19 (CKß11, ELC, MIP3ß, Scya19, Exodus-3) and CCL21 (CKß9, SLC, MIP2ß, Scya21, Exodus-2). In recent years, the role of chemokines in directing the migration of lymphocytes has been well-characterized. One of the most important mediators of homeostatic trafficking of naïve T cells to secondary lymphoid organs (SLO) is the chemokine receptor CCR7. Binding of its ligands, CCL19 and CCL21, mediates the transendothelial migration of T cells across high endothelial venules into SLO. It has also been demonstrated that CCR7 plays a role in the localization of dendritic cells and B cells during an immune response.
In addition to its significant role in the chemotaxis of lymphocytes, human CCR7 has also been recognized as a marker for a distinct subset of memory T cells, the central memory (TCM) population. These cells are characterized by the expression of CCR7 and CD62L and reside within peripheral lymphoid organs.
CCR7 also plays a role in thymocyte development and its deficiency leads to disturbed thymic architecture, aberrant T cell development, and limited thymocyte expansion.
