Obesity drives chronic inflammation in tissues like the liver and adipose tissue. Peroxisome proliferator-activated receptors (PPARs) are key regulators of these inflammatory responses and metabolic processes.

Area of Science:

  • Metabolic Disorders and Inflammation
  • Molecular Mechanisms of Obesity

Background:

  • Rising global obesity rates increase healthcare burdens and metabolic disease prevalence.
  • Obesity leads to ectopic fat deposition (liver, muscle) and adipose tissue dysfunction, promoting inflammation.
  • Adipose tissue macrophages contribute to obesity-induced inflammation via secreted mediators.

Purpose of the Study:

  • To review the role of peroxisome proliferator-activated receptors (PPARs) in obesity-induced inflammation.
  • To explore PPAR modulation of inflammatory responses in adipose tissue, liver, and vascular walls.

Main Methods:

  • Literature review focusing on PPARs and obesity-induced inflammation.
  • Analysis of molecular mechanisms linking PPARs to metabolic and inflammatory pathways.

Main Results:

  • PPARs regulate lipid and glucose metabolism, energy homeostasis, and inflammatory responses.
  • Obesity-induced inflammation involves complex molecular pathways modulated by PPARs.
  • PPARs are implicated in adipose tissue, liver, and vascular inflammation associated with obesity.

Conclusions:

  • PPARs represent a significant therapeutic target for mitigating obesity-related inflammation and metabolic consequences.
  • Understanding PPAR function is crucial for developing strategies against obesity-induced pathologies.
