... process and cause of Parkinson's disease. However, researchers believe that a protein called alpha-synuclein misfolds and clumps in many forms of the disease, and that this process is intimately tied ...
... their next step is to test therapeutic agents that mitigate this pro-inflammatory response to alpha-synuclein. They say they have a good lead on design of these drugs – their research has shown that ...
... but there are inherited forms of Parkinson's. Some of these can be linked to mutations in the gene for alpha-synuclein or triplications of the gene. The mutations and triplications cause the brain to ...
