Model Analysis of Helper T Cell Differentiation
Helper T (Th) cells regulate immune responses by producing various cytokines upon antigen stimulation. Helper T cells can be divided into two subsets, Th1 and Th2 [2]. The Th1 cells are responsible for defense against infectious intracellular microorganisms. The Th2 cells are responsible for defense against extracellular pathogens and the development of allergic immune reactions. The SOCS famil...
متن کاملT-cell differentiation: Commitment factors for T helper cells
The immune system is designed to eradicate a large variety of invading pathogens with minimum immunopathology. T helper cells, also known as CD4+ T cells, may be subdivided into the T helper 1 (Th1) and the T helper 2 (Th2) subsets, which produce distinct profiles of cytokines [1,2]. These Th1 and Th2 cells have opposing roles, regulating immune responses to intracellular and extracellular path...
متن کاملCell division curtails helper phenotype plasticity and expedites helper T-cell differentiation.
Following activation by antigen, helper T cells differentiate into one of many effector phenotypes. Formulating mechanistic mathematical models combining regulatory networks at the transcriptional, translational and epigenetic level, we study how individual helper T cells may adopt their different phenotypes. For each cytokine phenotype, for example, T helper type 1 (Th1) and type 2 (Th2) cells...
متن کاملCytokine transcriptional events during helper T cell subset differentiation
The molecular basis for changes in cytokine expression during T helper (Th) cell subset differentiation is not well understood. We have characterized transcriptional events related to cytokine gene expression in populations of naive T cell receptor-transgenic T cells as they are driven in vitro toward Th1 or Th2 phenotypes by interleukin (IL)-12 or IL-4 treatment, respectively. Quantitative rev...
متن کاملT helper cell differentiation: on again, off again.
Recent studies raise the possibility that T helper (Th) polarization may be attributable to generalized activation and regulated silencing rather than regulated activation of target cytokine genes. The binding of transcription factors GATA-3 or T-bet to specific enhancers does recruit transcription factors such as NFAT-1 to IL-4 or IFNgamma promoters, respectively; however, GATA-3 also intrinsi...
