• The drug is based on one of the chemical features of Parkinson’s — that people with the disease lack dopamine in the brain. Dopamine is a chemical messenger that is needed for nerve cells to communicate with each other. It is therefore essential for controlled body movements.
  • The new nanotech drug works, according to the research note, by effectively delivering dopamine to the brain. The trick is doing so in a way that maintains the integrity of the blood-brain barrier (which avoids pathogens reaching the brain.) The studies on rats indicate that you must combine dopamine with biodegradable nanoparticles.
  • With the success of trials in rate, further studies will be carried out with primates. Eventually a drug delivery system suitable for use with people could be created and put into use.
