Mutations of polyomavirus VP1 allow in vitro growth in undifferentiated cells and modify in vivo tissue replication specificity.

abstract：:It has been suggested that vaccination prior to infection may direct the mutational evolution of human immunodeficiency virus type 1 (HIV-1) to a less fit virus, resulting in an attenuated course of disease. The present study was initiated to explore whether prior immunization might prevent the reversion of the virus ...
