Role of Selective Leptin Resistance in Diet-Induced Obesity Hypertension

Abstract

Leptin is an adipocyte-derived hormone that plays a key role in the regulation of body weight through its actions on appetite and metabolism. Leptin also increases sympathetic nerve activity (SNA) and blood pressure. We tested the hypothesis that diet-induced obesity is associated with resistance to the metabolic actions of leptin but preservation of its renal SNA and arterial pressure effects, leading to hypertension. Mice were fed a high-fat diet for 10 weeks to induce moderate obesity. The decrease in food intake and body weight induced by intraperitoneal or intracerebroventricular leptin was significantly attenuated in the obese mice. Regional SNA responses to leptin were differentially altered in diet-induced obese mice. Renal SNA response to leptin was preserved, whereas lumbar and brown adipose tissue SNA responses were attenuated in obese mice. Radiotelemetric arterial pressure was ∼10 mmHg higher in obese mice. Furthermore, the increase in arterial pressure in response to long-term (12 days) leptin treatment was preserved in obese mice. Thus, mice with diet-induced obesity exhibit circulating hyperleptinemia and resistance to the metabolic actions of leptin. However, there is preservation of the renal sympathetic and arterial pressure responses to leptin, which represent a potential mechanism for the adverse cardiovascular consequences of obesity.

  • Although the suppressive effects of leptin on food intake are blunted in obesity, its acute stimulatory actions on renal sympathetic nerve activity seem to be preserved, suggesting selective leptin resistance.

    “Although the suppressive effects of leptin on food intake are blunted in obesity, its acute stimulatory actions on RSNA seem to be preserved, suggesting selective leptin resistance126,136.”
  • In obese mice, leptin's anorexic effects were blunted whereas the acute effects to increase RSNA were preserved.

    “In obese mice, leptin’s anorexic effects were blunted whereas the acute effects to increase RSNA were preserved104.”
  • Initial studies suggested that while the effects of leptin on satiety and energy metabolism were resistant, the sympathoexcitatory effects were maintained.

    “Initial studies purporting this concept suggested that while the effects of leptin on satiety and energy metabolism were resistant, the sympathoexcitatory effects were maintained (60, 61, 222, 223, 290, 291).”

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.
