CCL28 is also known as mucosa-associated epithelial chemokine (MEC) and CCK1. It is expressed by columnar epithelial cells in the gut, lung, breast and salivary glands, and its expression can be increased by a number of stimulants incluiding proinflammatory cytokines. It is involved in homing of T and B lymphocytes that express CCR10 and migration of eosinophils that express CCR3. CCL28 has been implicated in a number of disease processes including atopic dermatitis, asthma, psoriasis, vulgaris, and bullous pemphigoid.
