Involvement of CCL25 (TECK) in the generation of the murine small-intestinal CD8alpha alpha+CD3+ intraepithelial lymphocyte compartment.
(2002) In European Journal of Immunology 32(12). p.3488-3497- Abstract
- The CC chemokine CCL25 (TECK) is selectively expressed in the thymus and small intestine, indicating a potential role in T lymphocyte development. In the present study we examined the role of CCL25 in the generation of the small-intestinal CD8alpha alpha(+)CD3(+) intraepithelial lymphocyte (IEL) compartment. CCL25 mRNA expression in the murine small intestine increased at three weeks of age and corresponded with the appearance of CD8alpha alpha(+)CD3(+) lymphocytes in the small-intestinal epithelium. Administration of monoclonal neutralizing anti-CCL25 antibody to two-week-old mice led to a approximately 50% reduction in the total number of CD8alpha alpha(+)TCRgamma delta(+) and CD8alpha alpha(+)TCRalpha beta(+) IEL at four weeks of age....

Freshly isolated murine CD8alpha alpha(+)CD3(+) IEL migrated in response to CCL25 and expressed the CCL25 receptor, CCR9. Analysis of CCR9 expression on putative IEL precursor populations demonstrated the presence of both CCR9(-) and CCR9(+) cells and indicated that up-regulation of this receptor occurred during IEL precursor differentiation. Finally, data from wild-type and RAG(-/-) mice suggested that the reduction in CD8alpha alpha(+)CD3(+) IEL in anti-CCL25 antibody treated mice resulted primarily from defective maintenance and/or development of IEL precursors rather than a direct effect on mature CD8alpha alpha(+)CD3(+) IEL.
