title: [Kinetic changes of plasma IL-1 and IL-6 levels in MPTP-induced Parkinson's disease model mice and their relationship with brain asymmetry].
abstract: OBJECTIVE
  To set up Parkinson's disease (PD) model mice by using 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP), detect the levels of plasma IL-1 and IL-6, and to explore their relationship with brain asymmetry.
  
  
  METHODS
  Male C57BL/6J mice were divided into right pawed mouse group and left pawed mouse group according to paw preference test which reflects brain asymmetry. Mice were injected intraperitoneally with 25 mg/kg MPTP each day for 5 consecutive days. The mice were executed and blood samples were taken at 1, 3 and 14 days after the last time injection. Control mice were only injected with normal saline. The levels of plasma IL-6 and IL-1 were detected by ELISA.
  
  
  RESULTS
  Plasma IL-6 level in normal control mice was low, but elevated dramatically at 14 days after last time injection of MPTP in PD model mice. Furthermore, IL-6 level of right pawed mice was higher than that of left pawed mice. Plasma IL-1 levels also increased on day 3 after last time injection of MPTP, and the level of left pawed mice was higher than that of right pawed mice.
  
  
  CONCLUSIONS
  IL-6 and IL-1 probably participate in the occurrence and progress of MPTP-induced PD in model mice, and were related with brain asymmetry.
