German scientists have found further evidence that Parkinson's disease may be autoimmune. They used stem cell models to demonstrate that the cells of the immune system attack dopamine, which produces cells of people with Parkinson's disease, but not those of people who do not suffer from this disease
. In Parkinson's disease, brain cells that produce dopamine are dead and the reason is unknown.
As more cells disappear, dopamine levels decline and symptoms such as tremors, slow movements, stiffness, and balance problems become more pronounced. Problems with speech, difficulty swallowing and uncontrolled movements are also reported, writes Medical News Today.
In autoimmune diseases, the immune system attacks healthy organs, tissues and cells instead of protecting them.
Although the idea that Parkinson's disease may be an autoimmune disease is not new, the biological evidence that supports this topic was almost not so numerous.
It is only recently that scientists have associated the use of drugs that relieve immune system reactions to the reduction of Parkinson's disease risk.
This new study from the University of Friedrich Aleksander of Erlangen was published in Cell Stem Cell magazine
