Abstract

The differentiation of naive CD4(+) T cells into lineages with distinct effector functions has been considered to be an irreversible event. T helper type 1 (Th1) cells stably express IFN-gamma, whereas Th2 cells express IL-4. The discovery and investigation of two other CD4(+) T cell subsets, induced regulatory T (iTreg) cells and Th17 cells, has led to a rethinking of the notion that helper T cell subsets represent irreversibly differentiated endpoints. Accumulating evidence suggests that CD4(+) T cells, particularly iTreg and Th17 cells, are more plastic than previously appreciated. It appears that expression of Foxp3 by iTreg cells or IL-17 by Th17 cells may not be stable and that there is a great degree of flexibility in their differentiation options. Here, we will discuss recent findings that demonstrate the plasticity of CD4(+) T cell differentiation and the biological implications of this flexibility.

  • TH1 cells are responsible for host defense against intracellular microbes and implicated in systemic autoimmunity; TH2 cells fight extracellular parasites and are involved in anaphylactic reactions; TH17 cells mediate immunity against extracellular bacteria and fungi as well as organ-specific autoimmunity.

    “The former group encompasses functionally distinct populations including T H 1 cells responsible for host defense against intracellular microbes and implicated in systemic autoimmunity, T H 2 cells that fight off extracellular parasites and are involved in anaphylactic reactions and T H 17 cells that mediate immunity against extracellular bacteria and fungi as well as organspecific autoimmunity (Z”

  • The current view is that CD4 Th cell subsets are not separate lineages but have plasticity and form a continuum of mixed functional capacities.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
