A study in humans demonstrated that plasma-derived exosomes from severe trauma patients exhibit significant downregulation of 60 microRNAs, including 12 with direct roles in hematopoiesis, compared to operative controls [Munley et al. DOI:10.1097/TA.0000000000004225]. A study in rhesus macaques demonstrated that the mir-376a-1 was utilized as a feature in a dose-prediction model at Day 9 and in a pleural effusion prediction model at Day 6 [May et al. DOI:10.1038/s41598-022-16316-x].
