Web26 Feb 2024 · Cytokines produced early in the innate or adaptive immune response to microbes promote the differentiation of naive CD4 T cells into TH1, TH2, or Th17 cells by activating transcription factors that stimulate production of the cytokines of each subset (the early induction step). Progressive activation leads to stable changes in the expressed ... T-Helferzellen (abgekürzt TH-Zellen) sind eine Gruppe der T-Lymphozyten, die eine Helferfunktion haben. Sie werden anhand der von ihnen ausgeschütteten Zytokine in zwei wichtige Untergruppen (Subpopulationen) eingeteilt, die verschiedene Funktionen haben. Eine Untergruppe (genannt Typ1-T-Helferzellen) ist an der zellulären Immunantwort beteiligt, während die andere U…
