Acquisition of lymphokine-producing phenotype by CD4+ T cells

Seder, R A, Paul, W E·1994·Annual Review of Immunology

Abstract

Naive CD4+ T cells when stimulated produce IL-2 as their major lymphokine. Upon priming, these cells develop into cells that produce either IFN gamma, TNF beta, and IL-2 or IL-4 and its congeners. The former cells are designated TH1-like, and the latter TH2-like. Here we review the regulation of the differentiation of naive CD4 cells into IFN gamma- or IL-4-producers. The dominant factors that determine such differentiation are lymphokines and other cytokines. IL-2 itself appears to be required for naive cells to develop into TH1- or TH2-like cells but is not deterministic of their differentiation fate. If IL-4 is also present during the priming period, the resultant CD4+ T cells produce IL-4 upon restimulation; the development of IFN gamma-producing cells is strikingly inhibited by IL-4. In the absence of IL-4, priming for IFN gamma-production occurs, but this is markedly enhanced by IL-12. The role of IFN gamma in enhancing priming for IFN gamma-production is not fully resolved. In some in vitro systems, it appears to act together with IL-12 to enhance such production. Anti-IFN gamma diminishes priming for IFN gamma production in vivo. Lymphokines also exert a "cross-regulatory" or inhibitory effect. As noted above, IL-4 strikingly diminishes priming for IFN gamma production, although this inhibitory effect is blunted in the presence of IL-12. IFN gamma similarly diminishes priming for IL-4 production; this effect is principally observed when low concentrations of IL-4 are used in the priming culture. Although other factors may play a role in the determination of lymphokine-producing phenotype, such as antigen dose, type of antigen-presenting cell, and expression of accessory molecules and hormones, these effects appear to be secondary to the dominant role of the lymphokines and cytokines.

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.
