lentiviral vectors are promising gene delivery tools capable of transducing a variety of dividing and non-dividing cells, including pluripotent stem cells which are refractory for transduction by murine retroviruses. although there is a growing debate on the safety of lentiviral vectors for gene transfer, in particular for those derived from human immunodeficiency viruses, type one (hiv-1) and ...

background: bovine viral diarrhea virus (bvdv) causes significant economic and health effects in cattle farms. because of the relative inefficiency of bvdv eradication programs, in recent years, numerous strategies such as anti-viral gene therapy has been used extensively to fight it. one of the ways to evaluate the quality of these anti-viral strategies is the study of their efficacy in the sp...

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 (lvs) are useful vehicle for genetransfer to dividing and non-dividing cells and genetic manipulations. however, the use of lentiviruses in studies requires an accurate titration technique.quantitative real-time pcr (qpcr) is a sensitive technique for the indication and quantitation of retrovirals particles. in this study, we used the qpcr for lentiviral vector titeration. th...

Hematopoietic stem cell (HSC) gene therapy using retroviral vectors has immense potential, but vector-mediated genotoxicity limits use in the clinic. Lentiviral vectors are less genotoxic than gammaretroviral vectors and have become the vector of choice in clinical trials. Foamy retroviral vectors have a promising integration profile and are less prone to read-through transcription than gammare...

Objective(s): Non-invasive treatment options for retinoblastoma (RB), the most common malignant eye tumor among children, are lacking. Epithelial growth factor receptor (EGFR) accelerates cell proliferation, survival, and invasion of many tumors including RB. However, RB treatment by targeting EGFR has not yet been researched. In the current study, we investigated the effect of EGFR down-regula...
