Lentiviral vector interactions with the host cell

Abstract

Lentiviral vectors (LVs)-mediated gene transfer is an efficient method for ex vivo and in vivo gene therapy. Actually, LVs have been used in several clinical trials and therapeutic correction was reached in affected patients. However, in order to be effective gene therapy needs to be efficient without detrimental effects for target cells. Successful cell transduction by LVs can be hampered by several factors such as the activation of innate immune sensors during cell transduction and different restriction factors (RFs) inhibiting viral replication inside the cells. Therefore, a better knowledge of host-vector interactions is important for the development of more efficient gene therapy strategies improving the LVs platform by limiting harmful responses.
