Description

CCL20 (MIP-3α) is the sole known chemokine ligand for CCR6, making it a critical mediator in the recruitment of dendritic cells, Th17 cells, and B cells to sites of mucosal inflammation. This tag-free recombinant mouse CCL20 encompasses the full mature sequence (residues 28–97) and demonstrates potent chemotactic activity in a CCR6-transfected BaF3 migration assay at 0.1–10 ng/mL, providing a reliable positive control for Transwell chemotaxis experiments, CCR6 signaling pathway studies involving NF-κB and MAPK activation, and in vivo murine models of intestinal or pulmonary inflammation. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts that can confound immune cell migration and activation readouts, which is especially important when working with primary dendritic cells or macrophages. Purity exceeding 96% by SDS-PAGE, combined with this stringent endotoxin control, supports use as a reference standard in cytokine detection assays and as a coating antigen for anti-CCL20 antibody validation by ELISA.

Target Background

Function

Acts as a ligand for C-C chemokine receptor CCR6. Signals through binding and activation of CCR6 and induces a strong chemotactic response and mobilization of intracellular calcium ions. The ligand-receptor pair CCL20-CCR6 is responsible for the chemotaxis of dendritic cells (DC), effector/memory T-cells and B-cells and plays an important role at skin and mucosal surfaces under homeostatic and inflammatory conditions, as well as in pathology, including cancer and autoimmune diseases. CCL20 acts as a chemotactic factor that attracts lymphocytes and, slightly, neutrophils, but not monocytes. Involved in the recruitment of both the proinflammatory IL17 producing helper T-cells (Th17) and the regulatory T-cells (Treg) to sites of inflammation. Required for optimal migration of thymic natural regulatory T cells (nTregs) and DN1 early thymocyte progenitor cells. Positively regulates sperm motility and chemotaxis via its binding to CCR6 which triggers Ca2+ mobilization in the sperm which is important for its motility. May be involved in formation and function of the mucosal lymphoid tissues by attracting lymphocytes and dendritic cells towards epithelial cells.
