Human Sinonasal Mucosa Heterogeneity Study

Recruiting now

Conditions studied: Human Sinonasal Mucosal Spatial Atlas

In brief

This observational study aims to better understand how the lining of the nose and sinuses differs across different sinonasal sites in humans, including participants with and without sinonasal inflammatory disease. Mucosal tissue samples will be collected from participants who are undergoing clinically indicated sinonasal surgery. The study will compare tissue structure, gene expression, protein expression, and immune cell composition among different regions of the sinonasal mucosa. By studying these differences, researchers hope to identify site-specific features of human sinonasal mucosa and improve understanding of normal and disease-related changes in the nose and sinuses. This study does not assign participants to any treatment or intervention. The findings may provide a foundation for future research on chronic rhinosinusitis, nasal polyps, and other sinonasal diseases.
