Background CCL28, also known as Mucosae-associated Epithelial Chemokine (MEC), is secreted by gastrointestinal and non-intestinal mucosal cells. It regulates chemotaxis of cells expressing surface receptors CCR3 and CCR10. This chemokine is constitutively expressed in the colon, but its levels can be increased by pro-inflammatory cytokines and certain bacterial products implying a role in effector cell recruitment to sites of epithelial injury. CCL28 has also been implicated in the migration of IgA-expressing cells to the mammary gland, salivary gland, intestine and other mucosal tissues. It has also been shown as a potential antimicrobial agent effective against certain pathogens, such as Gram negative and Gram positive bacteria and the fungus Candida albicans.
