A VECTOR FOR POLYNUCLEOTIDE VACCINES

摘要

The invention is a "humanized" polynucleotide vector vaccine which uses covalent closed circular plasmid DNA, "naked DNA", to express target antigens. The vector is non-replicating in mammalian cells but is capable of extended stable expression of the target sequences in skeletal muscle and professional antigen presenting cells generating an immune response to the target antigen in immunized individuals. The polynucleotide vector is particularly useful in accommodating monomorphic and polymorphic nucleic acid sequences encoding tumor antigens via PCR technology.
