CCR9, a chemokine receptor, is expressed in thymocytes and T lymphocytes from the small intestine and colon but not in lymphocytes from tonsils, lung, inflamed liver, normal or inflamed skin, inflamed synovium and synovial fluid, breast milk, and seminal fluid (Kunkel et al., 2000). CCR9 is not detected in natural killer cells, monocytes, eosinophils, basophils, and neutrophils. CCR9 binds TECK (thymus-expressed chemokine), a CC chemokine expressed in thymus and small intestine. TECK chemoattracts dendritic cells, thymocytes, and activated macrophages.
