Alterations in Mast Cell and Macrophage Infiltration, as Well as Micro Vessel Density

Plain-language summary

Obesity is a global health problem that has reached epidemic proportions, affecting more than one billion people worldwide and significantly increasing the risk of multiple comorbidities, including type 2 diabetes, cardiovascular diseases, and cancer (World Health Organization, 2024). Increasing evidence suggests that chronic low-grade inflammation associated with obesity plays a critical role in the development of obesity-related malignancies, including gastric cancer. Adipose tissue dysfunction in obesity leads to the recruitment and activation of various immune cells, such as macrophages and mast cells, which contribute to a pro-inflammatory microenvironment through the release of cytokines, growth factors, and angiogenic mediators.
