Exercise and IL‐6 infusion inhibit endotoxin‐induced TNF‐α production in humans

Abstract

During "nondamaging" exercise, skeletal muscle markedly releases interleukin (IL)-6, and it has been suggested that one biological role of this phenomenon is to inhibit the production of tumor necrosis factor (TNF)- alpha, which is known to cause pathogenesis such as insulin resistance and atherosclerosis. To test this hypothesis, we performed three experiments in which eight healthy males either rested (CON), rode a bicycle for 3 h (EX), or were infused with recombinant human IL-6 (rhIL-6) for 3 h while they rested. After 2.5 h, the volunteers received a bolus of Escherichia coli lipopolysaccharide endotoxin (0.06 ng/kg) i.v. to induce low-grade inflammation. In CON, plasma TNF-alpha increased significantly in response to endotoxin. In contrast, during EX, which resulted in elevated IL-6, and rhIL-6, the endotoxin-induced increase in TNF-alpha was totally attenuated. In conclusion, physical exercise and rhIL-6 infusion at physiological concentrations inhibit endotoxin-induced TNF-alpha production in humans. Hence, these data provide the first experimental evidence that physical activity mediates antiinflammatory activity and suggest that the mechanism include IL-6, which is produced by and released from exercising muscles.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In humans, infusion of rhIL-6, mimicking exercise-induced IL-6 increase, inhibited the increase in endotoxin-induced TNF-α plasma levels.

    “In humans, infusion of rhIL-6, an experimental procedure that mimics the increase in IL-6 levels induced by exercise, was able to inhibit the increase in endotoxin-induced TNF-α plasma levels (Starkie et al., 2003).”
  • Exercise prior to endotoxin totally blunted the increase in circulating levels of TNF-α that was observed during a resting situation.

    “Exercise prior to endotoxin totally blunted the increase in circulating levels of TNF‐α that was observed during a resting situation.”

    From Muscle–Organ Crosstalk: The Emerging Roles of Myokines (2020) · cites this paper as [113]

  • Infusion of rhIL-6 prior to endotoxin administration blunts the TNF-α response in humans.

    “It was therefore expected that an infusion of rhIL-6 prior to endotoxin administration would also blunt the TNF‐α response in humans and this was in fact what was found (113).”

    From Muscle–Organ Crosstalk: The Emerging Roles of Myokines (2020) · cites this paper as [113]

  • Healthy subjects were randomized to either rest or exercise prior to endotoxin administration.

    “We infused a very low dose of Escherichia coli endotoxin to healthy subjects, who were randomized to either rest or exercise prior to the endotoxin administration (113).”

    From Muscle–Organ Crosstalk: The Emerging Roles of Myokines (2020) · cites this paper as [113]

  • In healthy humans, a single exercise bout or an IL-6 infusion reduced the TNF increase caused by lipopolysaccharide infusion.

    “In healthy humans, one bout of exercise or an IL-6 infusion blunted the increase in circulating levels of TNF induced by infusion of lipopolysaccharide128.”

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.
