Obesity triggers systemic inflammation, impacting innate immunity and potentially causing or worsening gut inflammation. Adipose tissue releases inflammatory molecules, contributing to inflammatory bowel disease development.
Area of Science:
- Immunology
- Gastroenterology
- Metabolic Diseases
Background:
- Obesity is a growing global health concern.
- Obesity is linked to chronic low-grade inflammation.
- The interplay between obesity, innate immunity, and gut inflammation requires further elucidation.
Purpose of the Study:
- To review recent data on how obesity affects innate immunity.
- To explore the role of obesity-associated conditions in gut inflammation development.
Main Methods:
- Literature review of recent studies.
- Analysis of data on adipose tissue components and inflammation.
- Examination of adipokines and their role in immune-mediated diseases.
Main Results:
- Obesity increases proinflammatory cytokine release and adipocyte immune receptor expression.
- Adipose tissue molecules (adipokines) promote an inflammatory environment.
- Leptin may directly contribute to inflammatory bowel disease.
- Obesity-associated inflammation links to angiogenesis and neovascularization, favoring gut inflammation.
Conclusions:
- Obesity-related systemic changes predispose individuals to gut inflammation.
- Obesity may exacerbate existing inflammatory bowel disease progression.
