Naïve CD4+ T-cell subset differentiation/polarization
Naïve CD4+ T-cell subset differentiation/polarization is an in vitro assay in which purified naïve CD4+ T cells are activated through TCR and CD28 costimulation and cultured with defined cytokines and neutralizing antibodies to generate Th0, Th1, Th2, Th17, or induced Treg-like populations. Differentiation is detected by subset-associated cytokines and transcription factors: IFN-γ/T-bet for Th1, IL-4/GATA3 for Th2, IL-17A/RORγt for Th17, and Foxp3 for induced Treg cells. The assay readout is usually generated by intracellular cytokine staining after restimulation, transcription-factor staining by flow cytometry, ELISA of secreted cytokines, or gene-expression analysis. The result reflects cytokine-directed lineage commitment or polarization rather than antigen-specific immune protection by itself.
