pher Touloukian, at Indiana University School of Medicine, Indianapolis, has developed an approach that led to long-lived antitumor immune responses by CD4+ T cells in a mouse model of melanoma skin cancer. They hope that it might be possible to one day translate this approach for clinical benefit.

METABOLIC DISEASE: Uncovering new way to stop fat accumulation in mice

The most common cause of liver dysfunction in the United States is a condition known as nonalcoholic fatty liver disease (NAFLD). A form of NAFLD known as hepatic steatosis is associated with obesity and type 2 diabetes. It arises as a result of increased generation and accumulation of lipids (fats) in the liver. Renaud Dentin and colleagues, at Institut Cochin, France, have now provided new insight into the mechanisms underlying hepatic steatosis in mice. Specifically, they find a role for the proteins p300 and SIK2 in regulating lipid production in the liver. Taken together, all the data lead the authors to suggest that SIK2 activators and specific p300 inhibitors might provide new approaches to treating hepatic steatosis in individuals with obesity and type 2 diabetes.
