UCLA Study Finds Link Between Neural Stem Cell Overgrowth And Autism-like Behavior in Mice
People with autism spectrum disorder often experience a period of accelerated brain growth after birth. No one knows why, or whether the change is linked to any specific behavioral changes. A new study by UCLA researchers demonstrates how, in pregnant mice, inflammation, a first line defense of the immune system, can trigger an excessive division of neural stem cells that can cause "overgrowth" in the offspring's brain.
UCLA Researchers Find That Drug Used for Another Disease Slows Progression of Parkinson's
A new study from UCLA found that a drug being evaluated to treat an entirely different disorder helped slow the progression of Parkinson's disease in mice. The study, published in the October edition of the journal Neurotherapeutics, found that the drug, AT2101, which has also been studied for Gaucher disease, improved motor function, stopped inflammation in the brain and reduced levels of alpha-synuclein, a protein critically involved in Parkinson's.
