Pitt team finds molecular pathway that leads to inflammation in asthma
Date:8/8/2011

eriments showed that knocking down 15LO1 decreased the dissociation of Raf-1 from PEBP1, which in turn reduced ERK activation. The pathway ultimately influences the production of factors involved in inflammation and mucus production.

"These results show us on both a molecular and mechanistic level and as mirrored by fresh cells from the patients themselves that the epithelial cells of people with asthma are very different from those that don't have it," Dr. Wenzel said. "It also gives us a potential treatment strategy: If we can prevent Raf-1 displacement, we might have a way of stopping the downstream consequences that lead to asthma."
