Abstract

The 'help' provided by CD4+ T lymphocytes during the priming of CD8+ T lymphocytes confers a key feature of immune memory: the capacity for autonomous secondary expansion following re-encounter with antigen. Once primed in the presence of CD4+ T cells, 'helped' CD8+ T cells acquire the ability to undergo a second round of clonal expansion upon restimulation in the absence of T-cell help. 'Helpless' CD8+ T cells that are primed in the absence of CD4+ T cells, in contrast, can mediate effector functions such as cytotoxicity and cytokine secretion upon restimulation, but do not undergo a second round of clonal expansion. These disparate responses have features of being 'programmed', that is, guided by signals that are transmitted to naive CD8+ T cells during priming, which encode specific fates for their clonal progeny. Here we explore the instructional programme that governs the secondary response of CD8+ T cells and find that helpless cells undergo death by activation-induced cell death upon secondary stimulation. This death is mediated by tumour-necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL). Regulation of Trail expression can therefore account for the role of CD4+ T cells in the generation of CD8+ T cell memory and represents a novel mechanism for controlling adaptive immune responses.

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.
