SAN DIEGO – Sometimes, scientific breakthroughs occur when researchers aren’t exactly looking for them. While attempting to better understand the function of a protein in connective tissue cells, UC San Diego School of Medicine scientists found a way to transform multiple types of cells into neurons. This discovery has led to the development of a treatment that eliminates symptoms of Parkinson’s disease in mice. The protein researchers were studying, called PTB, is known for its general role in activating or deactivating genes within a cell. In an attempt to better understand how PTB contributes to cell function, researchers silenced the...
