Pathological browning of white adipose tissue (WAT) is observed across various diseases, suggesting it may be an atypical stress response rather than a protective mechanism. Further research is needed to understand its role in disease progression.
Area of Science:
- Adipose tissue biology
- Metabolic adaptation
- Pathophysiology
Background:
- Brown and beige adipose tissues are thermogenic adaptations in mammals.
- White adipose tissue (WAT) browning enhances energy expenditure.
- Pathological browning of WAT occurs in chronic diseases, but its significance is unclear.
Purpose of the Study:
- To review evidence of pathological adipose tissue browning in human diseases and animal models.
- To explore the pathophysiological significance of adipose tissue browning in disease states.
Main Methods:
- Literature review of studies reporting adipose tissue browning.
- Analysis of pathological browning in conditions including cancers, kidney disease, burns, atherosclerosis, SARS-CoV-2, and sepsis.
Main Results:
- Adipose tissue browning is consistently observed across diverse pathological contexts.
- This browning may represent an atypical response to pathological stress, not its classical protective role.
Conclusions:
- The role of pathological browning as a compensatory mechanism or disease byproduct is unresolved.
- Future research should investigate triggers and functional outcomes of pathological browning to understand adipocyte plasticity and disease progression.
