TRanscriptomic Analysis of Circulating Endothelial Cells During Sepsis - TRACES Study (TRACES)

Dysfunction and Endothelial Repair in Sepsis Shock : RNAseq Transcriptomic Analysis of Circulating Endothelial Cells

Vascular dysfunction is an important mechanism involved in organ failure, in the setting of sepsis condition, with different types of circulating endothelial cells.Transcriptom analysis via RNAseq in different types of circulating endothelial cells, comapring critically ill patients with or without sepsis will allow determining differential gene expression for signal pathways in endothelial alteration and restoration associated with sepsis.
