 AB    OBJECTIVE: To create altered HIV-1 proviruses, containing foreign genes,
       capable of autonomous replication with either a transdominant inhibitory
       phenotype or an attenuated phenotype for pathogenicity. METHODS: Four
       HIV-1 proviruses separately containing a PKR gene, an HSV-1 thymidine
       kinase gene, an HTLV-I Tax gene, and a ribozyme gene were created. These
       proviruses were tested in continuous T-lymphocyte cultures either alone
       or in co-cultivation with wildtype HIV-1 to assay for attenuated
       pathogenicity versus transdominant inhibitory properties. RESULTS: We
       have found that proviruses containing PKR, HSV tk, and ribozyme have
       capacities to be transdominant inhibitors of wildtype HIV-1. An altered
       HIV-1 containing HTLV-I Tax showed highly reduced pathogenicity in
       lymphocyte cultures. DISCUSSION: Attenuated HIVs are potentially useful
       vaccine candidates. Transdominant HIVs that in themselves have been
       constructed to be attenuated are useful for therapeutic considerations.
