Beta thalassemia gene therapy using lentiviral vectors
Recent years, allogeneic bone marrow transplantation (BMT) has proved to be the successful cure for patients with thalassemia major, however this is restricted due to limited matched-related donor. Its complications include chronic graft-versus-host disease in 5-8% of patients. So, a molecular approach, such as gene therapy for direct normal beta globin gene transmission, seems quite promising ...
متن کاملDesigning Lentiviral Gene Vectors
Gene therapy relies on the delivery of therapeutic genes into patients’ cells. The microdevices used to reach the cells and to transfer the gene payload are called gene vectors. Viral packaging machinery is often utilized to generate the particles transporting the cargo genes. Lentiviruses, a subgroup of retroviruses, are highly suitable for remodeling into gene transfer vectors because they of...
متن کاملNonintegrating foamy virus vectors.
Foamy viruses (FVs), or spumaviruses, are integrating retroviruses that have been developed as vectors. Here we generated nonintegrating foamy virus (NIFV) vectors by introducing point mutations into the highly conserved DD35E catalytic core motif of the foamy virus integrase sequence. NIFV vectors produced high-titer stocks, transduced dividing cells, and did not integrate. Cells infected with...
متن کاملReplicative fidelity of lentiviral vectors produced by transient transfection.
Previous investigations have estimated the human immunodeficiency virus type 1 (HIV) base pair substitution rate to be approximately 10(-4) to 10(-5) per round of viral replication, and HIV has been hypothesized to be more error-prone than other retroviruses. Using a single cycle reversion assay, we unexpectedly found that the reversion rates of HIV, avian leukosis virus and Moloney murine leuk...
متن کاملLentiviral vectors and gene therapy.
Gene therapy is a novel method under investigation for the treatment of genetic, metabolic and neurologic diseases, cancer and AIDS. The primary goal of gene therapy is to deliver a specific gene to a pre-determined target cell, and to direct expression of such a gene in a manner which will result in a therapeutic effect. Retroviral vectors have the ability to integrate in the host cell DNA irr...
