ANTI-HIV VACCINES CONSTRUCTED BASED ON AMINO ACID MUTATION OF ATTENUATED LIVE VACCINE OF EIAV

摘要

Provided are antigenic polypeptides of HIV envelope glycoproteins which are constructed based on amino acid mutation of attenuated live vaccine of Equine Infectious Anemia Virus, DNA constructions and recombinant virus vectors comprising polynucleotides encoding said polypeptides, antibodies against said polypeptides as well as uses thereof in preventing and treating HIV infection. Said antigenic polypeptides and vaccines can induce high titer neutralization antibodies against HIV in organism.
