WebWe show that MHCII + Lgr5 + ISCs are non-conventional antigen-presenting cells in co-cultures with CD4 + T helper (Th) cells. Stimulation of intestinal organoids with key Th cytokines affects Lgr5 + ISC renewal and differentiation in opposing ways: pro-inflammatory signals promote differentiation, while regulatory cells and cytokines reduce it. WebTwo transcription factors have been found that play a critical role in the choice between becoming a Th1 or a Th2 cell.. T-bet for Th1 cells ; GATA3 for Th2 cells . T-bet produces Th1 cells by turning on the genes needed for Th1 function (e.g., for IFN-γ) blocking the activity of GATA3. Mice whose genes for T-bet have been "knocked-out" lack Th1 cells …
