S100A11 and Sepsis: By analyzing in detail the expression patterns of these genes in sepsis patients and their associations with the prognosis of sepsis patients, this study aims to reveal the possibility of these genes as de novo markers of sepsis, laying the foundation for further research on the regulatory mechanisms of S100A11, IFITM2, and QPCT in sepsis and their clinical significance, and providing the possibility of developing new therapeutic targets for sepsis.
