![عکس صفحه اول مقاله: High cell surface expression of CD4 allows distinction of CD4+CD25+ antigen-specific effector T cells from CD4+CD25+ regulatory T cells in murine experimental autoimmune encephalomyelitis High cell surface expression of CD4 allows distinction of CD4+CD25+ antigen-specific effector T cells from CD4+CD25+ regulatory T cells in murine experimental autoimmune encephalomyelitis](/preview/png/3065313.png)
Analysis of T regulatory cells (Treg) and T effector cells (Teff) in experimental autoimmune encephalomyelitis is complicated by the fact that both cell types express CD4 and CD25. We demonstrate that encephalitogenic T cells, following antigen recognition, up-regulate cell surface expression of CD4. The CD4high sub-population contains all of the antigen response as shown by proliferation and cytokine secretion, and only these cells are capable of transferring EAE to naive animals. On the other hand, a FACS separable CD25+ sub-population of cells displayed consistent levels of CD4 prior to and after antigen stimulation. These cells displayed characteristics of Treg, such as expressing high levels of the Foxp3 gene and the ability to suppress mitogenic T cell responses.
