Impact of L-DOPA treatment of patients with Parkinson's disease on mononuclear subsets and phagocytosis in the peripheral blood.

Until now, the question as to the role of immunological mechanisms in neuronal death of extrapyramidal cell systems in Parkinson's disease (PD) has not been fully resolved. One of the approaches includes examination of circulating blood cells. In our studies on 24 PD patients, peripheral blood was studied before and after medication with L-DOPA compounds.
