Immune Dysregulation in Obesity.

Area of Science:

• Immunology
• Metabolic Health
• Obesity Research

Background:

• Obesity is a growing global health concern characterized by chronic inflammation and systemic dyshomeostasis.
• There is increasing interest in understanding how obesity impacts immune system function.
• Obesity is increasingly viewed as both a metabolic and an immunological state.

Purpose of the Study:

• To review current findings on how obesity reshapes immune function.
• To explore obesity's influence on microbial defense, inflammatory diseases, and antitumor immunity.
• To examine obesity's modulation of immune cells, particularly T cells in adipose tissue.

Main Methods:

• Literature review of seminal and recent findings.
• Synthesis of research on obesity's effects on immune cell function.
• Focus on T cell roles in adipose tissue during obesity.

Main Results:

• Obesity fundamentally alters immunological states, affecting homeostasis.
• Obesity impacts microbial defense, inflammatory conditions like asthma, and antitumor immunity.
• Obesity influences immune function within tissues, especially adipose tissue via T cells.

Conclusions:

• Systemic metabolism critically shapes immune cell functions in obesity.
• Understanding these links has profound implications for tissue homeostasis.
• Future research should investigate long-term immunological effects of obesity and weight loss interventions.
