RNA 형광 제자리 혼성화(FISH)를 통해 Caenorhabditis elegans 장에서 미생물 집락화 및 감염을 시각화합니다.

Executive Industry Relevance

RNA FISH enables direct visualization and quantification of microbial colonization and infection within Caenorhabditis elegans intestines, providing a robust model for interrogating host-microbe interactions relevant to mammalian systems. This approach supports early-stage discovery by clarifying microbial dynamics in a genetically tractable organism, informing translational research and mechanistic de-risking for microbiome-targeted therapeutics. The method's ability to detect diverse microbes, including those lacking genetic tools, enhances predictive confidence in preclinical model selection and target validation.
