2-Hydroxyglutarate Metabolism Is Altered in an in vivo Model of LPS Induced Endotoxemia

The metabolic response to endotoxemia closely mimics those seen in sepsis.Here, we show that the urinary excretion of the metabolite 2-hydroxyglutarate (2HG) old taylor whiskey 1933 price is dramatically suppressed following lipopolysaccharide (LPS) administration in vivo, and in human septic patients.We further show that enhanced activation of the enzymes responsible for 2-HG degradation, D- and L-2-HGDH, underlie this effect.To determine the role of supplementation with 2HG, we carried out co-administration of LPS and 2HG.

This co-administration in mice modulates a number of aspects of physiological responses to LPS, and in particular, protects against LPS-induced hypothermia.Our results identify a novel role for 2HG in endotoxemia pathophysiology, and suggest that this metabolite may be a critical diagnostic and therapeutic target puffy spa headband for sepsis.
