Ligand-pseudoreceptor system for generation of adenoviral vectors with altered tropism

摘要

In accordance with the present invention, there is provided a modified virus ablated of its natural receptors interactions with an unmodified or non-naturally occurring cell, said modified virus comprising a non-native polypeptide, said modified virus having an altered tropism conferred by said non-native peptide, and replicating only in cells that can interact with said non-native peptide, said virus being incapable of infecting a cell through a CAR-dependent entry pathway. There is also provided a modified cell line for replicating the modified virus. These two together can be advantageously put into practice in the field of medicine and more particularly in gene therapy.
