Description
Chemokine (C-C motif) ligand 25 (CCL25) is a small cytokine belonging to the CC chemokine family that is also known as TECK (Thymus-Expressed ChemoKine). CCL25 is believed to play a role in the development of T-cells.1 It is chemotactic for thymocytes, macrophages, and dendritic cells. CCL25 is expressed in the small intestinal epithelium and plays an important role in mediating lymphocyte recruitment to this site.2 CCL25 is also highly expressed in the thymus, where it binds to its receptor CCR9 on thymocytes promoting migration and activation.3
