title: Production of non-infectious human immunodeficiency virus-like particles which package specifically viral RNA.
abstract: A recombinant vector that rapidly produces large amounts of human immunodeficiency virus (HIV) virus-like particles (VLPs) was constructed. This vector lacks LTR sequences and a functional nef gene. The VLPs produced are non-infectious but similar in structure to mature, infectious HIV virions. They package specifically HIV RNAs containing appropriate signals and do not package abundant cellular mRNAs (e.g. actin). In the system described here, efficient particle production and release is decoupled from infection. Use of this VLP system offers many advantages over the study of infectious virions, permitting the expression of mutant phenotypes which interfere with virus infectivity.
