High-fat diet makes mice susceptible to liver injury

A high fat diet may kill regulatory T cells in the liver, allowing steatosis (simple fatty liver) to develop into steatohepatitis (fatty liver with inflammation), according to the results of a new study in the November issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD).
