Abstract

Abstract: The effects of exogenous toxins (MPP+, rotenone) and potentially neurotoxic properties of levodopa (L-DOPA) on the survival rate of dopaminergic neurons in dissociated primary culture are presented. Dopamine agonists show a capacity to counteract MPP+-toxicity. Moreover, a preserving potential of the antioxidant and bioenergetic coenzyme Q10 (CoQ10) on the activities of tyrosine hydroxylase (TH), complexes I and II of the respiratory chain, and hexokinase activity in striatal slice cultures against MPP+ is demonstrated.
