Differential striatal spine pathology in Parkinson's disease and cocaine addiction: A key role of dopamine?
چکیده انگلیسی
Striatal projection neurons undergo a massive loss of dendritic spines in Parkinson's disease, while they display an abnormal overgrowth of “thin and immature” spines after chronic cocaine exposure. Accumbens D1 dopamine receptor-containing neurons are preferentially affected in response to chronic cocaine exposure. Dopamine and glutamate are key regulators of this spine plasticity. Opposite calcium-mediated regulation of the myocyte enhancer factor 2 (MEF2) induces these structural changes.
