title: [Expression of EBI3 and p28 mRNA in the brain and spinal cord of chronic model of experimental autoimmune encephalomyelitis in C57BL/6J mice].
abstract: OBJECTIVE
  To investigate the expression of EBI3 and p28 mRNA (the 2 subunits of IL-27) in the brain and spinal cord of the model of experimental autoimmune encephalomyelitis (EAE), and to explore their effect on EAE.
  
  
  METHODS
  Seventy-two adult female SPF C57BL/6J mice (inbred strain) were randomly divided into a control group, an adjuvant group, and an EAE group. RT-PCR was performed to detect the expression of EBI3 mRNA and p28 mRNA in the brain and spinal cord.
  
  
  RESULTS
  The expression of EBI3 mRNA and p28 mRNA was up-regulated at onset in the EAE group, which increased quickly during peak phase and maintained at a high level in the chronic phase. There was significant difference in the expression of EBI3 and p28 mRNA between the EAE group and the control/adjuvant group (P<0.01). Additionally, there was no remarkable difference in the expression of EBI3 and p28 mRNA in the brain and spinal cord between the control group and the adjuvant group (P>0.05).
  
  
  CONCLUSIONS
  IL-27 may play a role of promoting the morbility of EAE in the early stage, and sustain the inflammatory response in endgame.
