WebAuto-antigens formed of thyroid proteins, causing the activation of CD4+ cells and B cells, leading to autoantibody formation. CD4+ cells secrete inflammatory cytokines, which recruit macrophages and causes damage to the follicles. CD8+ cells are also attracted, which destroy thyroid follicular cells.

Since CD4 + T cells could be differentiated into specific T cell subtypes (T H 2 and T reg cells) subject to the cytokine milieu ( 28 ), we first analyzed the proportion of T reg cells in the intestinal LP and spleen. WebCD4 can improve the sensitivity of T cells to antigens and can accumulate Lck to the center region of IS after the initial exposure of DCs to T cells. CD4-deficient T cells have a reduced proliferative response to antigen stimulation and the effect of IS formation is also significantly reduced.
