MCP-1 (monocyte chemoattractant protein-1), PD-1/PD-L1 (programmed death receptor-1, a programmed death ligand-1), sTREM-1 (soluble triggering receptor expressed on myeloid cells-1), CD64 (neutrophil surface receptor), sCD14-ST (presepsin), and finally microRNAs are other promising but not widely used biomarkers of sepsis (29). This evidence concerns the gene CCL2 and Sepsis.
