Parkinson's disease is a common neurodegenerative disorder characterized by the progressive loss of the dopaminergic neurons in the substantia nigra pars compacta.The loss of these neurons is associated with a glial response composed mainly of activated microglial cells and, to a lesser extent, of reactive astrocytes.This glial response may be the source of trophic factors and can protect against reactive oxygen species and glutamate.he role of glial cells in Parkinson's disease.
