Respiratory flora:The potential biomarker of radiation-induced pulmonary injury

Radiation-induced pulmonary injury is a major dose-limiting toxicity that occurs due to thoracic radiotherapy.And the most widely used high-throughput technology,16S ribosomal RNA sequencing,is adopted for bacterial classification and identification of airway microbiome analysis.In this study,we provide novel insights into the composition pattern and predicted function of the lung microbiome in RIPI rats.Certain genus and species change in a dose-dependent manner,which might be capable of serving as novel bacterial biomarkers,as well as the potential targets for the future diagnosis or treatment of RIPI.In summary,our findings provide a vital reference for RIPI study,and will contribute to investigate the novel therapeutic or preventive management for RIPI.
