Combining neurologic and blood pressure drugs reduces breast tumor development in mice

Adding a medication used to treat epilepsy, bipolar disorder and migraines to a blood pressure medicine reversed some aspects of breast cancer in the offspring of mice at high risk of the disease because of the high fat diet fed to their mothers during pregnancy. Conversely, this treatment combination increased breast cancer development in the offspring whose mothers had not been fed a high fat diet during pregnancy.

Solving the puzzle of IgG4-related disease, the elusive autoimmune disorder

IgG4-related disease is an autoimmune disorder affecting millions and has no established cure. Previous research indicates that T cells, a major component of the immune system, and the immunoglobulin IgG4 itself are key causative factors, but the mechanism of action of these components is unclear. Now, scientists have meticulously explored this pathway in their experiments, and their research brings to light new targets for therapy.
