Microbial recognition by Toll-like receptors

Takeda, Kiyoshi, Akira, Shizuo·2004·Journal of Dermatological Science

Abstract

Toll-like receptors (TLRs) sense invasion of microorganisms by detecting microbial components that are conserved among pathogens. Recognition of microbial components by TLRs triggers activation of the innate immune system. Signaling pathways via TLRs originate from conserved cytoplasmic Toll/IL-1 receptor (TIR) domains. Recent accumulating evidence demonstrates that TIR domain-containing adaptors, such as MyD88, TIRAP/Mal, TRIF, and TRAM, regulate TLR-mediated signaling pathways. MyD88 is common to all TLR-mediated pathways, which lead to the production of inflammatory cytokines, whereas TRIF mediates induction of IFN-beta in TLR3 and TLR4 signaling pathways. TIRAP/Mal is implicated in the TLR2- and TLR4-mediated MyD88-dependent signaling pathway. TRAM is specifically involved in the TLR4-mediated TRIF-dependent pathway. Thus, TIR domain-containing adaptors play a pivotal role in TLR signaling pathways, which culminate in pathogen-specific 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.
