There is evidence that there may be a link between obesity and inflammation (irritation) in the body and the kinds of bacteria found in the gut. The goal of this study was to better understand how body weight in adults and the […]

Heritability of Innate Immune Inflammatory Responses

There are big differences in how people respond to severe bacterial infection.  The inflammatory response of white blood cells to harmful bacteria that invade the body may play an important role in determining how well a patient will be able to fight the infection. The purpose of this study was to better understand how genetic […]
