概括
17型免疫反应是由17A型介质素 (IL-17A) 驱动的,在牙周炎中促进口腔上皮细胞的增殖. 阻断IL-17A减少了这种增殖,这对于维持口腔上皮屏障至关重要.

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
