Distinct cell death markers identified in critical care patient survivors diagnosed with sepsis

•Decrease in serum caspase-1 and p62 in sepsis survivor patients compared to healthy controls.•Decrease in serum caspase-1 and MLKL compared to caspase-3 in sepsis survivor patients.•Basal levels of serum caspase-3, caspase-1, MLKL and p62 are not different in healthy controls.•Altered expression of cell death markers in PBMCs from septic survivors versus healthy controls.
