Inhibition of sepsis-induced inflammatory response by β1-adrenergic antagonists

Abstract

Continuous infusion of a B1AA initiated after septic insult improves survival at 5 days in a murine model. Benefits may be caused by modulation of gene expression in immunologic pathways leading to an increase in CAMP and TNFSF10 expression. This observed effect may be explained by the activation of NFKB and BRCA1 genes involved in immune response and cell repair pathways. Our findings support further investigation of the use of B1AA in the treatment of sepsis.
