The subthalamic nucleus (STN) is a small structure of the basal ganglia characterized by a high neuronal. projecting from the substantia nigra pars compacta (SNc) to the striatum are lost [1].

The pathogenesis of Parkinson's disease (PD) involves the interaction of environmental and genetic factors. Although mutations in known PD genes are responsible for only 10 % of PD cases, the discovery. The pathogenesis of different neurodegenerative diseases, such as Parkinson's. (PD) shares several common features. One of these is the abnormal accumulation and aggregation of disease-specific proteins, which is suggested to lead to neurodegeneration. Recent evidence also indicates that the. pathogenesis of Parkinson's disease (PD).

By using microarray analysis of peripheral blood leukocytes and substantia nigra brain tissue, I find out that idiopathic Parkinsonism is actually a TH17 dominant autoimmune disease. Summary of all previous literatures also support that. Purpose of review. Rapid progress in genetics has meant that there are now five genes identified for 'Parkinson's disease'. The detailed phenotypes vary, but generally the dominant genes cause a. Lewy body disease spectrum whereas recessive genes cause a milder parkinsonism with variable inclusion body pathology.
