Abstract

SUMMARY During acute infections, a small population of effector CD8 T cells evades terminal differentiation and survives as long-lived memory T cells. We demonstrate that the transcriptional repressor Blimp-1 enhances the formation of terminally differentiated CD8 T cells during LCMV infection, and Blimp-1 deficiency promotes the acquisition of memory cell properties by effector cells. Blimp-1 expression is preferentially increased in terminally differentiated effector and “effector memory” (TEM) CD8 T cells, and gradually decays after infection as central memory (TCM) cells develop. Blimp-1-/- effector CD8 T cells show some reduction in effector molecule expression, but primarily develop into memory precursor cells that survive better, and more rapidly acquire several TCM attributes, including CD62L and IL-2 expression and enhanced proliferative responses. These results reveal a critical role for Blimp-1 in controlling terminal differentiation and suppressing memory cell developmental potential in effector CD8 T cells during viral infection.

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.
