Abstract

As acute infections resolve, effector CD8(+) T cells differentiate into interleukin-7 receptor(lo) (IL-7R(lo)) short-lived effector cells (SLECs) and IL-7R(hi) memory precursor effector cells (MPECs) capable of generating long-lived memory CD8(+) T cells. By using another SLEC marker, KLRG1, we found that KLRG1(hi) effector cells began appearing early during infection and were committed to downregulating IL-7R. Unlike IL-7R(hi) MPECs, KLRG1(hi) IL-7R(lo) SLECs relied on IL-15, but IL-15 could not sustain their long-term maintenance or homeostatic turnover. The decision between SLEC and MPEC fates was regulated by the amount of inflammatory cytokines (i.e., IL-12) present during T cell priming. According to the amount of inflammation, a gradient of T-bet was created in which high T-bet expression induced SLECs and low expression promoted MPECs. These results elucidate a mechanism by which the innate immune system sets the relative amounts of a lineage-determining transcription factor in activated CD8(+) T cells and, correspondingly, regulates their memory cell potential.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Ag-specific CD8 T cells derived from the effector phase of a response can express various combinations of CD127 and KLRG1, defining SLECs (CD127−KLRG1+) that are lost during contraction or MPECs (CD127+KLRG1−) that are more likely to persist and contribute to memory.

    “Ag-specific CD8 T cells derived from the effector phase of a response can express various combinations of CD127 and KLRG1, which define either more short-lived effector cells (SLECs; CD127−KLRG1+), which are lost during the contraction phase of the immune response, or memory precursor effector cells (MPECs; CD127+KLRG1−), which are more likely to persist and contribute to memory populations [224,”

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.
