Abstract

The study of innate immunity and its link to inflammation and host defense encompasses diverse areas of biology, ranging from genetics and biophysics to signal transduction and physiology. Central to our understanding of these events are the Toll-like receptors (TLRs), an evolutionarily ancient family of pattern recognition receptors. Herein, we describe the mechanisms and consequences of TLR-mediated signal transduction with a focus on themes identified in the TLR pathways that also explain the operation of other immune signaling pathways. These themes include the detection of conserved microbial structures to identify infectious agents and the use of supramolecular organizing centers (SMOCs) as signaling organelles that ensure digital cellular responses. Further themes include mechanisms of inducible gene expression, the coordination of gene regulation and metabolism, and the influence of these activities on adaptive immunity. Studies in these areas have informed the development of next-generation therapeutics, thus ensuring a bright future for research in this area.

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.
