Parkinson’s disease: Study focuses on regulation of dopamine levels

11 diciembre 2014

A mechanism regulating dopamine levels in the brain has been revealed by a study on a mouse model of late onset Parkinson’s disease. Using gene expression profiling, a method to measure the activity of thousands of genes, researchers investigated dopaminergic neurons in the midbrain, which are nerve cells that use dopamine to send signals to other nerve cells. These neurons are known to degenerate in Parkinson’s disease.
