title: [Construction of recombinant eukaryotic expression plasmid of murine chemokine MIP-1alpha and coimmunization with HSV-II DNA vaccine].
abstract: OBJECTIVE
  To construct the recombinant eukaryotic expression plasmid of murine macrophage inflammatory protein-1alpha (MIP-1alpha) and investigate the effect of MIP-1alpha as an adjuvant on immune response induced by herpes simplex virus type II glycoprotein D (HSV-II gD) DNA vaccine.
  
  
  METHODS
  Using total RNA from RAW264.7 cells stimulated with LPS, the whole code sequence of murine MIP-1alpha was amplified by RT-PCR and inserted into pcDNA3 at Hind III/Xba I restriction sites. The recombinant eukaryotic expression plasmid Pm was transiently expressed in COS-7 cells and its specificity was demonstrated by RT-PCR and Boyden chemotaxis chamber assay. BALB/c mice were immunized with gD DNA vaccine and/or MIP-1alpha, and the effect of MIP-1alpha on gD DNA vaccine was evaluated by detecting anti-HSV-II antibody, antigen-specific lymphoproliferative responses, and examining survival rates after mice were challenged intravaginally with HSV-II.
  
  
  RESULTS
  The recombinant eukaryotic expression plasmid of murine MIP-1alpha was constructed, and it was revealed that immune responses of HSV-II gD DNA vaccine were enhanced by coimmunization with MIP-1alpha.
  
  
  CONCLUSIONS
  The murine MIP-1alpha can be used as an adjuvant of HSV-II gD DNA vaccine.
