Can we predict who is at risk of facing cognitive issues in PD and address them earlier? These are the questions being pursued by Dr. Goldman of the PDF Research Center at Rush University Medical Center.

Chronic degeneration of nigrostriatal projections, followed by nigral dopaminergic cell death, is a key feature of Parkinson disease (PD). This study examines the neuroprotective potential of the rho kinase inhibitor fasudil in the 6-hydroxydopamine (6-OHDA) mouse model of PD in vivo. C57Bl/6 mice were lesioned by striatal stereotactic injections with 4 ?g of 6-OHDA and treated with fasudil 30 or 100 mg/kg body weight via drinking water. Motor behavior was tested biweekly; histologic and biochemical analyses were performed at 4 and 12 weeks after lesion. Motor behavior was severely impaired after 6-OHDA lesion and was not improved by fasudil treatment. Fasudil 100 mg/kg did not significantly increase the number of dopaminergic cells in the substantia nigra after 12 weeks versus lesion controls. Interestingly, however, high-performance liquid chromatography analysis of dopamine metabolites revealed that striatal levels of 3,4-dihydroxyphenylacetic acid were significantly increased after 12 weeks, suggesting a regenerative response. In contrast to recent findings in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridin model, fasudil effects seem limited in this severe 6-OHDA model of PD. Nevertheless, high therapeutic concentrations of fasudil are suggestive of a proregenerative potential for dopaminergic neurons, making further evaluations of rho kinase inhibition as a proregenerative therapeutic strategy in PD promising.
