Boost for dopamine packaging protects brain in Parkinson's model

An increase in the protein that helps store dopamine, a critical brain chemical, led to enhanced dopamine neurotransmission and protection from a Parkinson's disease-related neurotoxin in mice in a recent study. Dopamine and related neurotransmitters are stored in small storage packages called vesicles by the vesicular monoamine transporter (VMAT2). When released from these packages dopamine can help regulate movement, pleasure, and emotional response.
