Molecular characterization of unique intersubtype HIV type 1 A1/C recombinant strain circulating in Pune, India.

abstract：:Mutant HIV virions, encoding C-terminally truncated Env proteins, exhibit a cell-specific replication defect, i.e., they can replicate in a few T cell lines (termed permissive cells) but not in the majority of T cell lines (termed nonpermissive cells). We have studied the properties of two mutant virions (pNL-Tr712 an...
