Official Full Name
chemokine (C-C motif) ligand 19
Background
Studies have shown that MIP-3B may play a role not only in inflammatory and immunological responses but also in normal lymphocyte recirculation and homing. In addition, this protein may play an important role in trafficking of T- cells in thymus, and T-cell and B cell migration to secondary lymphoid organs. MIP-3B specifically binds to chemokine receptor CCR7. Recombinant CCL19 shows potent chemotactic activity for T-cells and B-cells but not for granulocytes and monocytes. MIP-3B is expressed at high levels in the lymph nodes, thymus and appendix, intermediate levels in colon and trachea, and low levels in spleen, small intestine, lung, kidney and stomach. This gene is one of several CC cytokine genes clustered on the p-arm of chromosome 9. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. The cytokine encoded by this gene may play a role in normal lymphocyte recirculation and homing. It also plays an important role in trafficking of T cells in thymus, and in T cell and B cell migration to secondary lymphoid organs. MIP-3B specifically binds to chemokine receptor CCR7.
