T helper cells and cytokines
SpletFigure 1. Plasticity of human Th1 and Th2 cells.Naive CD4 + T cells are stem-cell-like cells that under the influence of different cytokines can differentiate to various types of effector cells including Th1, Th2, Th9, and T FH cells. Th1 and Th2 central memory cells are arrested at an early stage of differentiation, are highly plastic and some can still switch lineage.
