Selective expression of the interleukin 7 receptor identifies effector CD8 T cells that give rise to long-lived memory cells
Abstract
A major unanswered question is what distinguishes the majority of activated CD8 T cells that die after an acute viral infection from the small fraction (5-10%) that survive to become long-lived memory cells. In this study we show that increased expression of the interleukin 7 receptor alpha-chain (IL-7Ralpha) identifies the effector CD8 T cells that will differentiate into memory cells. IL-7R(hi) effector cells contained increased amounts of antiapoptotic molecules, and adoptive transfer of IL-7R(hi) and IL-7R(lo) effector cells showed that IL-7R(hi) cells preferentially gave rise to memory cells that could persist and confer protective immunity. Thus, selective expression of IL-7R identifies memory cell precursors, and this marker may be useful in predicting the number of memory T cells generated after infection or immunization.

“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.
