Summary
Tumour necrosis factor-alpha (TNF) plays a key role in obesity by influencing energy expenditure and fat storage. This review examines TNF's central role in modulating fat mass and metabolic health.
Area of Science:
- Biochemistry
- Metabolic research
- Immunology
Background:
- Tumour necrosis factor-alpha (TNF) is a pleiotropic cytokine with diverse metabolic functions.
- While linked to cachexia, emerging evidence implicates TNF in obesity pathogenesis.
- TNF influences energy expenditure, fat deposition, and insulin resistance.
Purpose of the Study:
- To review the multifaceted role of TNF in regulating body fat mass.
- To explore TNF's involvement in the metabolic dysregulation characteristic of obesity.
Main Methods:
- Literature review of existing studies on TNF and obesity.
- Analysis of experimental and clinical data on TNF's metabolic effects.
Main Results:
- TNF significantly impacts energy balance and adiposity.
- Evidence supports TNF's role in promoting insulin resistance in obesity.
- TNF modulates key pathways controlling fat deposition and mobilization.
Conclusions:
- TNF is a critical mediator in the development and maintenance of obesity.
- Targeting TNF pathways may offer therapeutic strategies for obesity and related metabolic disorders.
