Defects in a single protein involved in cell death may impair the immune system's ability to combat a herpes viral infection in the central nervous system, scientists have found in new research that examines a pediatric infection ...
University of Calgary researchers have identified a new oxygen sensing mechanism in a small population of spinal cord neurons capable of protecting the brain and other vital organs from low oxygen (hypoxia). As blood oxygenation ...
