title: Direct transfection of dendritic cells in the epidermis after plasmid delivery enhanced by surface electroporation.
abstract: The skin is rich in antigen-presenting cells and as such is an excellent target tissue for vaccination strategies. Electroporation is a physical delivery method that potentiates the uptake of DNA vaccines into target cells. Intradermal electroporation offers a minimally invasive solution to DNA delivery in the clinic. Here we describe the direct transfection of dendritic cells in the epidermis, using a surface dermal electroporation device, and specifically show a dendritic cell transfected with plasmid expressing green fluorescent protein. The dendritic cell has used its motile capabilities after transfection to move from the epidermis into the dermis, making its way to the lymphatic system.
