Molecular identification of a danger signal that alerts the immune system to dying cells

Shi, Yan, Evans, James E., Rock, Kenneth L.·2003·Nature

Abstract

In infections, microbial components provide signals that alert the immune system to danger and promote the generation of immunity. In the absence of such signals, there is often no immune response or tolerance may develop. This has led to the concept that the immune system responds only to antigens perceived to be associated with a dangerous situation such as infection. Danger signals are thought to act by stimulating dendritic cells to mature so that they can present foreign antigens and stimulate T lymphocytes. Dying mammalian cells have also been found to release danger signals of unknown identity. Here we show that uric acid is a principal endogenous danger signal released from injured cells. Uric acid stimulates dendritic cell maturation and, when co-injected with antigen in vivo, significantly enhances the generation of responses from CD8+ T cells. Eliminating uric acid in vivo inhibits the immune response to antigens associated with injured cells, but not to antigens presented by activated dendritic cells. Our findings provide a molecular link between cell injury and immunity and have important implications for vaccines, autoimmunity and inflammation.

Claims other papers make about this one

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

  • Pattern recognition receptors on dendritic cells may include endocytic receptors that stimulate antigen uptake, such as scavenger receptors and C-type lectin receptors.

    “Pattern recognition receptors (PRR) present on DC may include endocytic receptors that stimulate antigen uptake (including scavenger receptors and C-type lectin receptors)106.”

  • Reduction of uric acid is associated with substantially reduced neutrophil recruitment in the liver after acetaminophen-induced injury in two different mouse models.

    “For example, a reduction of uric acid, which is released from dying cells and has adjuvant activity in vivo21, was associated with substantially reduced neutrophil recruitment in the liver after acetaminophen-induced injury in two different mouse models13.”

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.
