- Obesity causes changes throughout the body, including the immune system. This study found obesity alters immune cells called mast cells in abdominal fat tissue, contributing to chronic inflammation.
- Understanding these biological mechanisms helps explain why bariatric surgery improves conditions beyond just weight loss.
- This is the only basic science publication on Dr. de la Cruz-Muñoz's CV, reflecting translational research bridging lab science and clinical care.
- This reinforces that obesity is a complex biological disease with measurable immune and inflammatory changes that bariatric surgery can address.
This basic science study published in Lipids in Health and Disease examined how leptin deficiency-induced obesity affects mast cell density in abdominal fat depots and lymph nodes in a mouse model. Mast cells are immune cells implicated in chronic low-grade inflammation characterizing obesity. Using leptin-deficient mice, the study analyzed mast cell density across fat compartments, contributing to understanding of how obesity alters adipose tissue's immune microenvironment. Dr. de la Cruz-Muñoz is a co-author.
