Gene Therapy Lentivirus Vectors Explained

These studies can be a precursor to the development of novel drugs which aim to block a gene-product to treat a disease Producing recombinant lentiviral vectors for gene therapy Infectious lentiviruses have three main genes coding for the viral proteins in the order: 5-gag-pol-env-3 (see figure 2) There are additional genes (also called accessory genes) depending on the virus (e g

Ex vivo gene transfer in the years to come

09 10 2001Ex vivo gene transfer of cytokines or novel viral vectors are under development that may also be used for efficient ex vivo gene transfer These include vectors derived from adeno-associated viruses as well as lentiviral vectors Conclusions Despite a continuous increase of efforts to establish in vivo protocols for gene transfer of arthritis ex vivo gene transfer of secreted factors

Frontiers

This novel vaccine technology was found to elicit broad potent and protective immunity that was comparable to viral delivery but without the inherent limitations of viral vectors Self-amplifying mRNA (HA) vaccines induce potent functional immune responses in mice and ferrets comparable to those elicited by a licensed influenza subunit vaccine preparation ( 168 )

E

To achieve a deletion efficiency in target cells after ex vivo infection and drug selection we constructed a self-activating vector that simultaneously deleted E and reconstituted the neomycin phosphotransferase gene Selection of the target cells for resistance to G418 (a neomycin analog) ensured that all integrated proviruses had E deleted The proviruses with E deleted were mobilized
