Mitochondrial Function in the Kidney and Heart, but Not the Brain, is Mainly Altered in an Experimental Model of Endotoxaemia

2019

Significant impairments in mitochondrial function are associated with the development of multi-organ failure in sepsis/endotoxaemia, but the data on the dynamics of simultaneous mitochondrial impairment in multiple organs are limited. The aim of this study was to evaluate the changes in heart, brain and kidney mitochondrial function in an experimental model of lipopolysaccharide (LPS)-induced endotoxaemia.Samples were collected 4 and 24 h after single injection of LPS (10 mg/kg) in mice. Marked increases in inflammation-related gene expression were observed in all studied tissues 4 h after LPS administration. At 24 h post LPS administration, this expression of inflammation-related genes rem…
