Effector B cells are called plasma cells and secrete antibodies, and activated T cells include cytotoxic T cells and …
SpletA dendritic cell that interacts with an already-activated helper T cell can become licensed. This occurs through the interaction of co-stimulatory molecules including B7 and CD40 on the dendritic cell, with CD28 and CD40 ligand on the T cell. Only licensed dendritic cells are able to activate cytotoxic T cells. SpletAfter their activation, naïve CD4 T cells differentiate into effector T h 1, T h 2, T h 17, or follicular helper T (T fh) cells (Zhu et al., 2010; Crotty, 2014). Differentiation into peripheral Treg cells can also occur, and these cells are discussed in the section entitled Regulatory T Cells. Each of these CD4 T cell types is defined by ...
