Alzheimer's gene poses both risk and benefits
Scientists drilling down to the molecular roots of Alzheimer's disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person's risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system's ability to protect the brain from amyloid beta, a key protein associated with Alzheimer's.

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.
