Recombinant Human MIP-3α

Macrophage Inflammatory Protein-3 Alpha (MIP3A) also known as CCL20 or liver activation regulated chemokine (LARC) is a small cytokine belonging to the CC chemokine family. It is strongly chemotactic for lymphocytes and weakly attracts neutrophils.¹ MIP3A is specifically expressed by the follicle-associated epithelia (FAE) covering intestinal Peyer's patches (PPs) and is the only known chemokine ligand for the chemokine receptor CCR6.² MIP3-alpha is produced by intestinal epithelial cells (including cells associated with mucosal lymphoid tissues), by keratinocytes in inflamed skin, and by cells in liver and lung.^3,4 It plays an important role in the inflammatory response of blood monocytes and tissue macrophages.
