Microglia Transplant Restores Brain Function in Neurodegeneration

featured 112133

Summary: Researchers at Stanford have developed a targeted brain-cell transplant technique that could change treatment prospects for Tay-Sachs and Sandhoff diseases. By selectively depleting diseased microglia and replacing them with healthy donor precursor cells, the team restored crucial lysosomal enzyme activity in the brain and dramatically extended lifespan and function in a mouse model. Treated … Read more

Blood Test Detects Depression and Bipolar Disorder

featured 73116

Summary: Researchers at Indiana University have developed a blood test that can measure how severe a person’s depression is, estimate their future risk of developing severe depression, and assess risk for bipolar disorder. The test, based on RNA biomarkers, also offers information that can help personalize treatment choices for individual patients. Source: Indiana University Globally, … Read more

The Gene Behind Aggression in Wild Songbirds

featured 67282

Summary: Blocking expression of the ER-alpha gene in white-throated sparrows reduces their aggression. Source: Emory Health Sciences New research reveals how variation in a single gene within a supergene alters behavior in a wild songbird, determining whether the white-throated sparrow exhibits higher or lower levels of aggression. The study, led by neuroscientists at Emory University, … Read more

Low Protein Diets May Accelerate Dementia, Amino Acids Slow It

featured 78328

Summary: A low-protein diet may accelerate neurodegeneration, while supplementation with Amino LP7—a specific blend of seven essential amino acids—appears to slow brain atrophy and reduce the progression of dementia-related deficits in preclinical models. Source: The National Institutes for Quantum Science and Technology Dementia, including Alzheimer’s disease, is a group of disorders marked by severe loss … Read more
