Foamy virus vector

Human foamy virus (HFV) is a retrovirus and specifically belongs to the genus Spumavirus. The spumaviruses are complex and significantly different from the other six genera of retroviruses in several ways. The foamy viruses derive their name from the characteristic ‘foamy’ appearance of the cytopathic effect … See more The first description of foamy virus (FV) was in 1954. It was found as a contaminant in primary monkey kidney cultures. The first isolate of the “foamy viral agent” was in 1955. Not too long after this, it was isolated … See more If, in fact, HFV is not pathogenic in humans and is a retrovirus, it is an ideal vector for gene therapy. Another important feature of the virus is that the Gag, Pol, and Env proteins are synthesized independently; this is important because it means that each … See more Most of the differences between the spumaviruses and the other retroviruses come from the life cycle.
