Characterization of envelope glycoprotein mutants for human T-cell leukemia virus type 1 infectivity and immortalization.

abstract：:Mixed infection of a cell by vesicular stomatitis virus (VSV) and retroviruses results in the production of progeny virions bearing the genome of one virus encapsidated by the envelope proteins of the other. The mechanism for the phenomenon of pseudotype formation is not clear, although specific recognition of a viral...
