TLRs, NLRs and RLRs: a trinity of pathogen sensors that co-operate in innate immunity

Creagh, Emma M., O’Neill, Luke A.J.·2006·Trends in Immunology

Abstract

Significant advances in our understanding of innate immunity have been made following the identification of three families of pathogen sensors: Toll-like receptors (TLRs), NOD-like receptors (NLRs) and RIG-I-like receptors (RLRs). Members of the TLR family recognize bacteria, viruses, fungi and protozoa; NLRs with known functions detect bacteria, and RLRs are anti-viral. It is likely that interplay between these families ensures the efficient co-ordination of innate immune responses, through either synergistic or co-operative signalling. Important interactions occur between TLRs and certain NLRs for inducing the pro-inflammatory cytokine interleukin (IL)-1beta. TLRs induce pro-IL-1beta production and prime NLR-containing multi-protein complexes, termed "inflammasomes", to respond to bacterial products and products of damaged cells. This results in caspase-1 activation and the subsequent processing of pro-IL-1beta to its active form. In this article, we hypothesize that during the first phase of the host response to infection, an important interplay occurs between these families, providing a substantial combinatorial repertoire in innate immunity.

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.
