Lentiviral vectors are more efficient at transducing quiescent hematopoietic stem cells than murine retroviral vectors. This characteristic is due to multiple karyophilic components of the lentiviral vector pre-integration complex. Lentiviral vectors are also able to carry more complex payloads than murine retroviral vectors, making it possible to deliver expression cassettes that direct either...

human growth hormone (hgh) is a protein with multiple roles in a range of biological functions such as protein, carbohydrates and lipid metabolisms as well as immunity, tissue development and overall growth. one of the major class of biopharmaceuticals in mammalian cells is the production of recombinant pharmaceutical proteins. in this study, we constructed a lentiviral vector carrying coding r...

Lentiviral vectors are promising tools for gene therapy in the CNS. It is therefore important to characterize their interactions with the immune system in the CNS. This work characterizes transgene expression and brain inflammation in the presence or absence of immune responses generated after systemic immunization with lentiviral vectors. We characterized transduction with SIN-LV vectors in th...

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...

Viral vectors based on lentiviruses, such as the human immunodeficiency virus, are able to transduce a broad spectrum of nondividing cells in vivo. This ability of lentiviral vectors makes them an attractive vehicle for gene transfer into the liver. In order to determine the requirements for efficient lentiviral gene transfer, we used a fluorescence imaging system, which allows the detection of...

The present study aimed to explore microRNA-126 (miR-126) as a novel therapeutic target for primary hypertension. The lentiviral vector containing human immunodeficiency virus 1 (HIV‑1), the miR‑126 gene knockdown viral vector (lenti-miR-126-KD), and control lentiviral vector (lenti‑scramble‑miR) were constructed. Spontaneously hypertensive rats were randomly divided into 4 groups, which receiv...

Efficient gene delivery in the central nervous system (CNS) is important in studying gene functions, modeling neurological diseases and developing therapeutic approaches. Lentiviral vectors are attractive tools in transduction of neurons and other cell types in CNS as they transduce both dividing and non-dividing cells, support sustained expression of transgenes, and have relatively large packa...
