Background

CCL25, also known as TECK (thymus-expressed chemokine), is a CC chemokine that regulates the trafficking of lymphocytes in the thymus and small intestine. Mature mouse CCL25 shares 40% and 81% amino acid sequence identity with an human and rat CCL25, respectively . CCL25 is produced by stromal cells in the thymus and epithelial cells of the small intestine, particularly the jejunum and ileum . It binds to and induces chemoattraction through CCR9 , and both human and mouse proteins act on human CCR9 . CCR9 is expressed on immature pre-T cells and thymocytes . CCL25 induces the homing of several lymphocyte populations to the small intestine , including Integrin alpha 4 beta 7+ gamma δ T cells , Integrin alpha E beta 7+ CD8+ T cells , and IgA-producing plasma cells . In cancer, functional CCR9 mediates the metastasis of melanoma cells to the small intestine , contributes to the CCL25-dependent migration and invasion of some breast carcinomas , and attracts mesenchymal stromal cells to CCL25-expressing multiple myelomas . CCL25 contributes to the severity of chronic inflammation in rheumatoid arthritis where it attracts CCR9+ monocytes and macrophages , in endometriosis where it promotes the invasiveness of stromal cells , and in atherosclerosis where it contributes to the accumulation of CCR9+ macrophages in arterial plaques .
