Shutdown of HIV-1 Transcription in T Cells by Nullbasic, a Mutant Tat Protein

Abstract excerpt

UNLABELLED: Nullbasic is a derivative of the HIV-1 transactivator of transcription (Tat) protein that strongly inhibits HIV-1 replication in lymphocytes. Here we show that lentiviral vectors that constitutively express a Nullbasic-ZsGreen1 (NB-ZSG1) fusion protein by the eEF1α promoter led to robust long-term inhibition of HIV-1 replication in Jurkat cells. Although Jurkat-NB-ZSG1 cells were infected by HIV-1, no...
