Abstract

OBJECTIVE: Obesity is characterized by chronic inflammation of adipose tissue, which contributes to insulin resistance and diabetes. Although nitric oxide (NO) signaling has antiinflammatory effects in the vasculature, whether reduced NO contributes to adipose tissue inflammation is unknown. We sought to determine whether (1) obesity induced by high-fat (HF) diet reduces endothelial nitric oxide signaling in adipose tissue, (2) reduced endothelial nitric oxide synthase (eNOS) signaling is sufficient to induce adipose tissue inflammation independent of diet, and (3) increased cGMP signaling can block adipose tissue inflammation induced by HF feeding. METHODS AND RESULTS: Relative to mice fed a low-fat diet, an HF diet markedly reduced phospho-eNOS and phospho-vasodilator-stimulated phosphoprotein (phospho-VASP), markers of vascular NO signaling. Expression of proinflammatory cytokines was increased in adipose tissue of eNOS-/- mice. Conversely, enhancement of signaling downstream of NO by phosphodiesterase-5 inhibition using sildenafil attenuated HF-induced proinflammatory cytokine expression and the recruitment of macrophages into adipose tissue. Finally, we implicate a role for VASP, a downstream mediator of NO-cGMP signaling in mediating eNOS-induced antiinflammatory effects because VASP-/- mice recapitulated the proinflammatory phenotype displayed by eNOS-/- mice. CONCLUSIONS: These results imply a physiological role for endothelial NO to limit obesity-associated inflammation in adipose tissue and hence identify the NO-cGMP-VASP pathway as a potential therapeutic target in the treatment of diabetes.

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.
