ABSTRACT
Objective:
To study the astragalus polysaccharides ( APS) effect on immune induced by influenza A virus HA2 eu-karyotic expression vector.Methods:
The HA2 encoded by the DNA vaccine vector was efficiently expressed in CHO cells, as determined by reverse transcription polymerase chain reaction ( RT-PCR) and fluorescence analysis.60 rats were divided into six groups randomly,which were immunized with normal saline,pEGFP-N1,pHA2/EGFP+different dose of APS by intramuscular injection.The control sera were collected before injection.After injected the 36th day, sera were collected to analyzing IFN-γ, IL-4 and IgG level.Results:
IFN-γ,IL-4 and IgG level of pHA2/EGFP+mAPS group was different from that of pEGFP-N1 group or pHA2/EGFP+lAPS group( P<0.05 ).Conclusion:
Middle dose of APS could increase immune induced by influenza A virus HA2 eukaryotic expression vector.
