Abstract
A gene delivery vector used to generate genetically modified dendritic cells and B-cells central to the immune system. As a result, genetic modification of cells bearing the CD40 target antigen on its surface can be used to modulate immunity. Previously, both dendritic cells and B-cells have been resistant to gene transfer. The present invention serves to mediate dramatic enhancements in gene transfer to these cell types. Simultaneous with gene transfer, the vector system described herein matures dendritic cells and B-cells to a more potent immunoregulatory status. This invention provides technology for genetic manipulation of dendritic cells and B-cells.
