Study Notes
Fate-specifying Cytokines
- Cytokines influence the differentiation of T cells into specific types.
- IFN-γ and IL-12 lead to the development of TH1 cells.
- IL-4, IL-5, and IL-13 promote TH2 cell formation.
- IL-17 and IL-22 drive TH17 cell development.
- IL-21 fosters TFH cell differentiation.
- TGF-β and IL-10 result in iTreg cell development.
- STAT proteins are transcription factors crucial in these pathways.
- Specific transcription factors like T-bet, GATA-3, RORyt, Bcl-6, and FoxP3 are also essential in these processes.
