Abstract

Physiological anti-inflammatory mechanisms can potentially be exploited for the treatment of inflammatory disorders. Here we report that the neurotransmitter acetylcholine inhibits HMGB1 release from human macrophages by signaling through a nicotinic acetylcholine receptor. Nicotine, a selective cholinergic agonist, is more efficient than acetylcholine and inhibits HMGB1 release induced by either endotoxin or tumor necrosis factor-alpha (TNF-alpha). Nicotinic stimulation prevents activation of the NF-kappaB pathway and inhibits HMGB1 secretion through a specific 'nicotinic anti-inflammatory pathway' that requires the alpha7 nicotinic acetylcholine receptor (alpha7nAChR). In vivo, treatment with nicotine attenuates serum HMGB1 levels and improves survival in experimental models of sepsis, even when treatment is started after the onset of the disease. These results reveal acetylcholine as the first known physiological inhibitor of HMGB1 release from human macrophages and suggest that selective nicotinic agonists for the alpha7nAChR might have therapeutic potential for the treatment of sepsis.

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?

  • Macrophages and other cytokine-producing cells express acetylcholine receptors that transduce an intracellular signal inhibiting cytokine synthesis.

    “Macrophages and other cytokine-producing cells express acetylcholine receptors (AChRs), which transduce an intracellular signal that inhibits cytokine synthesis (26,27).”
  • Treatment of mice with nicotine significantly reduced serum levels of HMGB1 in a cecal perforation model of lethal peritonitis.

    “Treatment of these mice with nicotine, a potent α7 nAChR agonist, significantly reduced serum levels of HMGB1, a cytokine mediator of lethality in this model (27).”
  • Ligand-receptor interaction on cytokine-expressing cells culminates in decreased nuclear translocation of NF-κB and activation of STAT3 via phosphorylation by JAK2 recruited to the α7 nAChR.

    “Ligand-receptor interaction on cytokine-expressing cells culminates in decreased nuclear translocation of NF-κB as well as activation of the transcription factor STAT3 via phosphorylation by JAK2, which is recruited to the α7 nAChR (Figure 3) (22,27).”
  • The α7 subunit of the nicotinic AChR is the best characterized cholinergic receptor that suppresses cytokines.

    “The best characterized of these cholinergic receptors that suppress cytokines is the α7 subunit of the nicotinic AChR (α7 nAChR).”
  • The cholinergic antiinflammatory pathway can control cytokine responses even when the disease process is already established.

    “Notably, nicotine administration did not begin until 24 hours after the onset of lethal peritonitis in this model, indicating that the cholinergic antiinflammatory pathway can control cytokine responses even when the disease process is already established (27).”

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.
