Health Problems

Scientists trying to identify the roots of sudden infant death syndrome (SIDS), the leading cause of death in U.S. infants between 1 month and 1 year old, have increasingly turned their attention to the neurotransmitter serotonin and the brain cells that produce it. Studies have linked serotonin-producing neurons to the regulation of breathing, which may go awry in SIDS. In […]

pH imbalance in brain cells may contribute to Alzheimer’s disease

Health Problems

Johns Hopkins Medicine scientists say they have found new evidence in lab-grown mouse brain cells, called astrocytes, that one root of Alzheimer’s disease may be a simple imbalance in acid-alkaline—or pH—chemistry inside endosomes, the nutrient and chemical cargo shuttles in cells. Astrocytes work to clear so-called amyloid beta proteins from the spaces between neurons, but decades of evidence has shown […]
