CMC1 and infection: There were 190 proteins with differential abundance in the EVs of infected patients, 6 relevant proteins associated with poor outcome and infection: in T cell-derived EVs PSME1 (involved in apoptosis), H2B1C and MTREX (involved in transcription regulation, DNA replication and DNA repair) were more abundant; in B cell-derived EVs, COHA1 (organization of extracellular matrix) was less abundant; and in monocyte-derived EVs, PCSK9 (cholesterol metabolism) and CMC1 (energy-related metabolic pathways) were less abundant.
