Best of Last Year – The top Medical Xpress articles of 2016
(Medical Xpress)—It was a big year for research involving overall health issues, starting with a team led by researchers at the UNC School of Medicine and the National Institutes of Health who unearthed more evidence that replacing butter with vegetable oils is not beneficial for cardiac health—linoleic acid in the oils, they found, might be just as bad as fat in butter. Also, a team at the University of Warwick in England found evidence showing that eating more fruit and vegetables can substantially increase happiness levels—over a period of months.

Scientists find gene variants causing NK cell deficiency, solving 12 year-long mystery for a family
An international team of scientists has solved a medical mystery that has affected a family for more than 40 years. The condition made most of the children in the family susceptible to severe viral infections, Epstein-Barr virus in particular. Two of the four siblings died due to the infections, one was unaffected by the condition and one has survived repeated infections. Discovering the cause of the condition has brought closure to the family, personal satisfaction to the researchers and a better understanding of the clinical manifestations of deficiencies in natural killer (NK) cells, the first responders to viral infections. The results appear in The Journal of Clinical Investigation.

Cancer checkpoint drug target governs metabolic changes in exhausted T cells
Reprogramming of the molecular pathways underlying normal metabolism is essential for T cell infection-fighting function and for the immune system to form a "memory" of the microbes it has already encountered. But exactly how metabolism in exhausted T cells is maintained in chronic infections and cancer is a missing element in this line of research. Now, a new study suggests that tweaking metabolic steps in combination with checkpoint blockade drugs may improve some cancer therapies, according to new research from the Perelman School of Medicine at the University of Pennsylvania. The team published their findings this week in Immunity.
