Familial Parkinson's disease (PD) has been linked to point mutations and duplication of the alpha-synuclein gene and mutant alpha-synuclein expression increases the vulnerability of neurons to exogenous insults. In this study, we analyzed the levels of dopamine and its metabolites in the olfactory bulb (OB), and nigrostriatal regions of transgenic mice(More)
TAK-285, an investigational, orally active HER2/EGRF inhibitor is in clinical development for potential use in HER2 over-expressing metastatic breast cancer. The objective of the present work was to verify the presence of unbound TAK-285 in the rat brain after oral administration by a microdialysis technique with simultaneous sampling of blood and brain. In(More)
The ability of 1-deprenyl to protect against the parkinsonian effects of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) has been attributed to the inhibition of conversion of MPTP to MPP+ (1-methyl-4-phenylpyridinium) catalyzed by MAO-B. We report here that deprenyl-treatment in mice has an additional neuroprotective element associated with the rapid(More)
Methamphetamine (5 mg/kg) administered 30 min prior to each injection with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) (3 x 30 mg/kg, at 24 h intervals) prevents the reduction of striatal levels of dopamine and its metabolites in C57BL mice. Methamphetamine and amphetamine inhibit the uptake of 1-methyl-4-phenylpyridinium (MPP+) by striatal(More)
