Immunoengineering strategies using nanoparticles for obesity treatment

Area of Science:

• Immunology
• Metabolic Disorders
• Obesity Research

Background:

• Obesity is a global epidemic linked to metabolic disorders, cardiovascular disease, and type 2 diabetes.
• Obesity-induced inflammation, particularly involving adipose tissue macrophages (ATMs), drives insulin resistance and metabolic dysfunction.
• Conventional obesity treatments have limitations, necessitating novel therapeutic strategies.

Purpose of the Study:

• To provide a comprehensive overview of obesity, its comorbidities, and treatment limitations.
• To explore the role of inflammation and immune dysregulation in obesity, focusing on ATMs.
• To examine immunomodulatory strategies, including macrophage polarization and adipose tissue browning, for obesity treatment.

Main Methods:

• Review of current literature on obesity, inflammation, and immune cells.
• Analysis of the mechanisms linking adipose tissue expansion to macrophage phenotype.
• Focus on nanoparticle-based strategies for immunomodulation in obesity.

Main Results:

• Obesity leads to chronic low-grade inflammation in adipose tissue.
• Expanding adipose tissue promotes infiltration and pro-inflammatory polarization of macrophages.
• Nanoparticle-based approaches show promise for targeting obesity-related inflammation.

Conclusions:

• Understanding macrophage polarization and adipose tissue browning is crucial for developing new obesity therapies.
• Nanoparticle-based immunomodulation presents a promising avenue for mitigating obesity-associated inflammation.
• This review offers insights into novel therapeutic strategies for the global obesity epidemic.
