Using a novel thymic stromal culture technique, we evaluated the ability of a hairpin ribozyme specific for simian immunodeficiency virus (SIV) and human immunodeficiency virus type 2 (HIV-2) to inhibit viral replication in T lymphocytes derived from transduced CD34+ progenitor cells.
Vector DNA could be detected in HIV-2 vector-transduced nondividing CD34(+) CD38(-) human hematopoietic progenitor cells but not in those cells transduced with murine vectors.
