    A simple drug cocktail that converts cells neighboring damaged neurons into functional new neurons could potentially be used to treat stroke, Alzheimer’s disease, and brain injuries. A team of researchers at Penn State identified a set of four, or even three, molecules that could convert glial cells – which normally provide support and insulation for neurons – into new neurons. A paper describing the approach appears online in the journal Stem Cell Reports on February 7, 2019.
