Abstract

T Follicular Helper Cell Differentiation: When B cells respond to an infection, they often require help from CD4 + T cells to mount a proper response. It is thought that a subset of CD4 + effector T cells, called T follicular helper cells (T FH ), performs this function. Several subsets of effector CD4 + T cells arise, depending on the type of infection, which have distinct transcriptional programs driving their differentiation. Whether this is also the case for T FH cells has not been clear (see the Perspective by Awasthi and Kuchroo ). Nurieva et al. (p. 1001 , published online 23 July) and Johnston et al. (p. 1006 ; published online 16 July) now demonstrate that the transcription factor Bcl6 is both necessary and sufficient for T FH differentiation and subsequent B cell–mediated immunity, suggesting that it is a master regulator of this lineage. Johnston et al. also show that expression of Bcl6 and the transcription factor, Blimp-1, are reciprocally regulated in T FH cells and that, when ectopically expressed, Blimp-1 inhibits T FH development.

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.
