The expansion of CD4~+ T lymphocytes in rats with colitis induced by 2, 4, 6- trinitrobenzene sulphonic acid / 中国病理生理杂志

ABSTRACT

AIM: To study on the expansion of CD~(4+) T lymphocytes isolated from rats with colitis induced by 2,4,6-trinitrobenzene sulphonic acid (TNBS). METHODS: The numeration and protein expression of CD~(4+) T lymphocytes had been performed by immunohistological analysis, flow cytometry and Western-blot. RESULTS: The numeration of CD4+ T cells and the protein expression of CD~(4+) T lymphocytes increased significantly in rats with colitis induced by 2,4,6-trinitrobenzene sulphonic acid. CONCLUSION: Expansion of CD~(4+) T lymphocytes in TNBS-induced colitis provides us a simple and reducible animal model for research of the new target of therapeutic drug.
