Self-limiting, cell type-dependent replication of an integrase-defective human immunodeficiency virus type 1 in human primary macrophages but not T lymphocytes.

Abstract excerpt

Integration of retroviral DNA into the host cell genome, catalyzed by the integrase (IN) protein, is thought to be required for replication. We show here that one IN-minus defective mutant of human immunodeficiency virus type 1 (HIV-1) is able to replicate in macrophages but not in peripheral blood lymphocytes (PBLs). Replication of the HIV-1 defective mutant, however, was inefficient and self-limiting. The...
