IELs can be divided into different subpopulations based on molecular markers expression, mainly by expression of TCR and CD8αα, and by origin. Also termed conventional IELs, express TCRαβ together with CD4 or CD8αβ and are derived from antigen-experienced T cells that home to intraepithelial space. Contrary to natural IELs, induced IELs are the progeny of MHCI-restricted CD8αβ or MHCII-restricted CD4 naïve T cells t… Web22 aug. 2024 · The epithelial-derived cytokine IL-33 plays a unique role in the activation of type 2 gene expression in human mast cells. Because of the observed association of intraepithelial mast cells with type 2 inflammation, we examined the regulation of mast cell type 2 gene expression by the epithelial-derived cytokines IL-33, IL-25, and TSLP.
