Abstract

Immune responses to vaccines require direct recognition of pathogen-associated molecular patterns (PAMPs) through pattern-recognition receptors (PRRs) on dendritic cells (DCs). Unlike vaccination, infection by a live pathogen often impairs DC function and inflicts additional damage on the host. Here we found that after infection with live influenza A virus, signaling through the interleukin 1 receptor (IL-1R) was required for productive priming of CD8(+) T cells, but signaling through the PRRs TLR7 and RIG-I was not. DCs activated by IL-1 in trans were both required and sufficient for the generation of virus-specific CD8(+) T cell immunity. Our data demonstrate a critical role for a bystander cytokine in the priming of CD8(+) T cells during infection with a live virus.

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.
