Researchers identify new weapon to fight deadly bacterial sepsis

blocking aldose reductase activity with pharmacological inhibitors or using small interfering RNAs (pieces of genetic material that specifically stop the production of particular cellular proteins) to prevent the cells from producing the enzyme in the first place, the researchers demonstrated that aldose reductase is essential to that cycle.

Previous work by Srivastava and his UTMB collaborators (including research described in a paper published Oct. 1 in Cancer Research) has demonstrated that blocking aldose reductase similarly can dramatically reduce the inflammation-driven processes of colorectal cancer and complications of diabetes.

"There are so many inflammatory signaling processes that depend on this enzyme, and so it made sense to look into with regard to sepsis, which we knew was a runaway inflammatory process," Srivastava said. "We're hoping that when an aldose reductase inhibitor is approved as a drug in the U.S. -- one is already in use in Japan for diabetes, by the way -- we can interest clinicians in studying its use against sepsis."
