Immunology cells and their functions

WitrynaAlthough these cytokines display some functional redundancy, their cell-specific functions during an immune response are determined by the expression of distinct receptor complexes (Figure 6). For instance, IL-4, IL-7, IL-9, and IL-21, bind to high-affinity receptor complexes consisting of a cytokine-specific alpha-chain and the γ c . WitrynaThe lack of CD226 alters the mucosal immune environment mainly by increasing Th cell responses and IL-17 and IL-22 levels, which might result, in part, from increased IgA + B cells in PPs and AMPs in the intestines. Additionally, CD226 may control the homeostasis of IELs and ILC3s in the lamina propria.
