Dopaminergic Pathways in Obesity-Associated Inflammation.

Area of Science:

• Immunology
• Neuroscience
• Metabolic Diseases

Background:

• Obesity is a global health issue linked to chronic inflammation and metabolic dysfunction.
• Obesity is associated with type 2 diabetes, cardiovascular diseases, cancer, neurodegenerative diseases, and psychiatric disorders.
• Dopaminergic pathways regulate appetite and feeding behaviors, and are increasingly recognized as immunoregulators.

Purpose of the Study:

• To review current knowledge on dopaminergic pathways in obesity-associated inflammation.
• To focus on the role of innate immune cells in this process.
• To propose a model integrating central and peripheral dopaminergic circuits in obesity-associated inflammation.

Main Methods:

• Literature review integrating current knowledge on dopaminergic pathways in obesity-associated inflammation.
• Focus on innate immune cell players.
• Development of a model for neuroimmune and metabolic system interactions in obesity.

Main Results:

• Dopaminergic pathways play a significant role in regulating inflammation associated with obesity.
• Dopamine (DA) modulates immune function, and immune cells produce endogenous DA.
• Dopaminergic immunomodulation in obesity-associated inflammation is largely unexplored.

Conclusions:

• Dopaminergic pathways are critical in obesity-associated inflammation, involving both central and peripheral systems.
• Understanding these pathways offers potential therapeutic strategies for obesity and related immunometabolic diseases.
• Dopaminergic drugs may hold promise for managing obesity-related inflammation.
