229. PGE2 Increases Lentiviral Vector Transduction Efficiency of Human HSC

Proteasome Inhibition Increases the Efficiency of Lentiviral Vector-Mediated Transduction of Trabecular Meshwork.

Purpose To determine if proteasome inhibition using MG132 increased the efficiency of FIV vector-mediated transduction in human trabecular meshwork (TM)-1 cells and monkey organ-cultured anterior segments (MOCAS). Methods TM-1 cells were pretreated for 1 hour with 0.5% dimethyl sulfoxide (DMSO; vehicle control) or 5 to 50 μM MG132 and transduced with FIV.GFP (green fluorescent protein)- or FI...

Lentiviral vector-mediated transduction of adult neural stem/progenitor cells isolated from the temporal tissues of epileptic patients

Objective(s): Neural stem/progenitor cells (NS/PCs) hold a great potential for delivery of therapeutic agents into the injured regions of the brain. Efficient gene delivery using NS/PCs may correct a genetic defect, produce therapeutic proteins or neurotransmitters, and modulate enzyme activation. Here, we investigated the efficiency of a recombinant lentivirus vector ...

Lentiviral vectors show dramatically increased efficiency of transduction of human leukemic cell lines.

Dextran Enhances the Lentiviral Transduction Efficiency of Murine and Human Primary NK Cells.

The efficient transduction of specific genes into natural killer (NK) cells has been a major challenge. Successful transductions are critical to defining the role of the gene of interest in the development, differentiation, and function of NK cells. Recent advances related to chimeric antigen receptors (CARs) in cancer immunotherapy accentuate the need for an efficient method to deliver exogeno...

Vectofusin-1 Promotes RD114-TR-Pseudotyped Lentiviral Vector Transduction of Human HSPCs and T Lymphocytes

Ex vivo transduction of human CD34+ hematopoietic stem/progenitor cells (hCD34+ HSPCs) and T lymphocytes is a key process that requires high efficiency and low toxicity to achieve effective clinical results. So far, several enhancers have been used to improve this process. Among them, Retronectin highly meliorates VSV-G and RD114-TR pseudotyped lentiviral vector delivery in hCD34+ HSPCs and T l...
