Furthermore, we collected a series of blood samples from sepsis patients on the day of ICU admission (day 0, patients are diagnosed as having sepsis and admitted to ICU on the same day) and 1, 3, 5, and 7 days after treatment (days 1, 3, 5, and 7, respectively) to monitor the dynamic changes of TREM2 expression. This evidence concerns the gene TREM2 and Sepsis.
