Inter-kingdom signalling: Communication between bacteria and their hosts

Open access
Hughes, David T., Sperandio, Vanessa·2008·Nature Reviews Microbiology

Abstract

Microorganisms and their hosts communicate with each other through an array of hormonal signals. This cross-kingdom cell-to-cell signalling involves small molecules, such as hormones that are produced by eukaryotes and hormone-like chemicals that are produced by bacteria. Cell-to-cell signalling between bacteria, usually referred to as quorum sensing, was initially described as a means by which bacteria achieve signalling in microbial communities to coordinate gene expression within a population. Recent evidence shows, however, that quorum-sensing signalling is not restricted to bacterial cell-to-cell communication, but also allows communication between microorganisms and their hosts.

  • Many microorganisms express receptors for eukaryotic hormonal signals that primarily act by regulating gene expression; for example, when exposed to norepinephrine, Campylobacter jejuni exhibits increased growth and virulence-associated properties in vitro.

    “Known as inter-kingdom signaling, many microorganisms express receptors for eukaryotic hormonal signals that primarily act by regulating gene expression [63], e.g., when exposed to norepinephrine, Campylobacter jejuni exhibited increased growth and virulence-associated properties in vitro [64].”
  • Autoinducer 3 binds to the bacterial membrane receptor QseC, which results in its autophosphorylation; QseC then phosphorylates its response regulator QseB to initiate a signaling cascade that activates expression of bacterial genes associated with virulence and motility, including the gene that presides over flagellum development.

    “Autoinducer 3 binds to the bacterial membrane receptor QseC, which results in its autophosphorylation. QseC then phosphorylates its response regulator, QseB, to initiate a complex signaling cascade that activates the expression of bacterial genes associated with virulence and motility, including the gene that presides over flagellum development.34”
  • In vitro norepinephrine stimulates the growth of several strains of enteric pathogens and magnifies the virulent properties of Campylobacter jejuni.

    “In vitro norepinephrine stimulates the growth of several strains of enteric pathogens (reviewed elsewhere34) and magnifies the virulent properties of Campylobacter jejuni.36”
  • The best-characterized microbial signaling system is analogous to the eukaryotic noradrenergic signaling system and involves autoinducer 3 and the bacterial QseC receptor.

    “Perhaps the best-characterized microbial signaling system is analogous to the eukaryotic, noradrenergic signaling system and involves autoinducer 3—a molecule produced by the microbiota and the bacterial QseC receptor.34,44”
  • Both norepinephrine and dynorphins are thought to be released into the gut lumen during perturbation of homeostasis.

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.
