Novel Viral Vector Systems for Gene Therapy

Novel Gene Therapy Viral Vector Using Non-Oncogenic Lymphotropic Herpesvirus

Despite the use of retroviral vectors, efficiently introducing target genes into immunocytes such as T cells is difficult. In addition, retroviral vectors carry risks associated with the oncogenicity of the native virus and the potential for introducing malignancy in recipients due to genetic carryover from immortalized cells used during vector production. To address these issues, we have estab...

Adenoviral vector systems for gene therapy

Adenoviral (Ad) vectors are widely used in gene therapies, recombinant viral vaccines, and basic science studies. The vectors can deliver therapeutic genes into cells to recover the lost function of some genes, to enhance the ability of host immune systems, or to increase the sensitivity of cancer cells to chemotherapeutic drugs. Several adenoviral vector systems have been developed: first-gene...

Advances in Viral Vector-Based TRAIL Gene Therapy for Cancer

Numerous biologic approaches are being investigated as anti-cancer therapies in an attempt to induce tumor regression while circumventing the toxic side effects associated with standard chemo- or radiotherapies. Among these, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has shown particular promise in pre-clinical and early clinical trials, due to its preferential ability to i...

Prospects for Foamy Viral Vector Anti-HIV Gene Therapy

Stem cell gene therapy approaches for Human Immunodeficiency Virus (HIV) infection have been explored in clinical trials and several anti-HIV genes delivered by retroviral vectors were shown to block HIV replication. However, gammaretroviral and lentiviral based retroviral vectors have limitations for delivery of anti-HIV genes into hematopoietic stem cells (HSC). Foamy virus vectors have sever...
