objective: autoimmune diseases precede a complex dysregulation of the immune system. t helper17 (th17) and interleukin (il)-17 have central roles in initiation of inflammation and subsequent autoimmune diseases. il-27 significantly controls autoimmune diseases by th17 and il-17 suppression. in the present study we have created genetic engineered mesenchymal stem cells (mscs) that mediate with l...

In this study, in order to facilitate and accelerate the production of eukaryotic protein alpha 1-antitrypsin (AAT) with correct post-translational modifications, a protein production system based on the transduction of CHO and COS-7 cells using lentiviral vectors was developed. Human AAT cDNA was cloned into a replication-defective lentiviral vector. The transgene AAT-Jred chimer was transferr...

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...

A retroviral vector system based on the human immunodeficiency virus (HIV) was developed that, in contrast to a murine leukemia virus-based counterpart, transduced heterologous sequences into HeLa cells and rat fibroblasts blocked in the cell cycle, as well as into human primary macrophages. Additionally, the HIV vector could mediate stable in vivo gene transfer into terminally differentiated n...

We compared the efficiency of transduction by an HIV-1-based lentiviral vector to that by a Moloney murine leukemia virus (MLV) retroviral vector, using stringent in vitro assays of primitive, quiescent human hematopoietic progenitor cells. Each construct contained the enhanced green fluorescent protein (GFP) as a reporter gene. The lentiviral vector, but not the MLV vector, expressed GFP in no...

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...
