Tumor necrosis factor-α (TNFα) was the first cytokine shown to be produced in adipose tissue and increased in conditions of obesity and insulin resistance ().TNFα is a potent mediator of adipose tissue and systemic insulin resistance ().TNFα induces insulin resistance through multiple … Nettet5. nov. 2024 · Chronic inflammation impacts the fat storage in adipose tissue, resulting in free fatty acid and triglyceride excesses in bloodstream and induction of insulin resistance in muscle and liver. Adipocytes crosstalk with macrophages, which are able to infiltrate fat masses, leading to obesity, inducing ectopic fat deposition in these tissues.
Nettet1. des. 2006 · Lastly, it is possible that in overnight fasted dogs acute changes in plasma insulin have a predominant direct effect on glycogenolysis, whereas at a later time point, insulin inhibits gluconeogenesis by a predominant indirect effect (secondarily to an inhibition of lipolysis in adipose tissue and proteolysis in skeletal muscle, thus … Nettet1. apr. 2009 · GH stimulates lipolysis and causes insulin resistance within 1–2 h, and these effects disappear after approximately 8 h (35, 36). The stimulating effect of GH on IGF-I production and action is a more chronic process, which, as previously discussed, depends on a positive energy balance and ensuing elevations in insulin.

Insulin is a potent inhibitor of lipolysis and acts primarily through its effect on phosphodiesterase and subsequent suppression of the formation of cAMP.
