Cross-sectional 

研究目的:

本研究旨在从微生物-免疫交互视角出发,首次提出“P.gingivalis → CCL2/CCR2→OLK进展”的级联调控假说,旨在揭示口腔菌群-免疫互作在癌前病变进展中的关键作用,为OLK癌变预警提供新型分子标志物,更将为靶向微生物-免疫轴的干预策略奠定理论基础。  

Objectives of Study:

This study aims to propose for the first time a cascade regulatory hypothesis of "P.gingivalis → CCL2/CCR2 → OLK progression" from the perspective of microbiota immune interaction, aiming to reveal the key role of oral microbiota immune interaction in the progression of precancerous lesions, provide novel molecular markers for OLK cancer warning, and lay a theoretical foundation for targeted intervention strategies on the microbiota immune axis.
