Cerebrospinal Fluid from Patients with Parkinson's Disease Alters the Survival of Dopamine Neurons in Mesencephalic Culture
We have previously demonstrated that extracts of striatal tissue from patients with Parkinson's disease (PD) increase the survival of dopamine neurons in mesencephalic cultures relative to striatal extracts from control patients. In the present study, ventricular cerebrospinal fluid (vCSF) from...

Zusammenfassung: | We have previously demonstrated that extracts of striatal tissue from patients with Parkinson's disease (PD) increase the survival of dopamine neurons in mesencephalic cultures relative to striatal extracts from control patients. In the present study, ventricular cerebrospinal fluid (vCSF) from patients with PD, Alzheimer's disease (AD), and age-matched controls was similarly assessed. vCSF samples were separated into >10-kDa and 10-kDa fractions from PD and AD patients contained 73 and 13%, respectively, more tyrosine hydroxylase immunoreactive neurons than cultures incubated with vCSF from age-matched controls. This trophic activity was positively correlated with the trophic activity present in striatal extracts from the same patients. The |
