Аннотация

Atypical antipsychotics (AAP) are used in the therapy of Parkinson's disease (PD) for elimination of psychotic symptoms. As the brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF) and cerebral dopamine neurotrophic factor (CDNF) play a crucial role in the PD treatment, the aim of our study was the investigation of the effects of chronic treatment with commonly used AAP, clozapine and quetiapine, on the motor behavior and the BDNF, GDNF and CDNF genes expression in the mouse brain in the PD model produced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Clozapine and quetiapine (1 mg/kg, i.p.) were administered 48 hours after the last MPTP injection, and treatment continued for the following 16 days. Then animals were euthanized, substantia nigra (SN), striatum (St) and hippocampus (Hc) were extracted for RT-PCR and tyrosine hydroxylase (TH) western blot assessment. MPTP treatment led to 50% depletion in the TH protein level in the St. MPTP caused significant decrease in both BDNF and GDNF mRNA level in the Hc and St, respectively. At the same time, increase in the GDNF expression in the MPTP + clozapine group in the SN was found. MPTP caused dramatic decrease in the CDNF mRNA level in the SN with simultaneous increase in the St. Both clozapine and quetiapine decreased it to a normal level in the St. The effect of AAP clozapine and quetiapine on the GDNF and CDNF genes expression in the pharmacological model of PD has been shown for the first time.
