摘要:
A process is provided to deliver polynucleotide-based gene expression inhibitors to cells in a mammal in vivo for the purpose of inhibiting gene expression in the cells. Inhibition is sequence-specific and relies on sequence similarity to of the polynucleotide-based gene expression inhibitor and the target nucleic acid molecule. Delivery of the polynucleotide-based gene expression inhibitor can enhance the efficacy of co-delivered small molecule drugs.
摘要:
A process is provided to deliver small interfering RNA to cells in vivo for the purpose of inhibiting gene expression in that cell. The small interfering RNA is less than 50 base-pairs in length. This process is practiced on post-embryonic animals. Inhibition is sequence-specific and relies on sequence identity of the small interfering RNA and the target nucleic acid molecule.

摘要:
Described is a process for intravascular delivery of a polynucleotide to an extravascular cell of a mammal to inhibit gene expression. A polynucleotide containing sequence that is similar to a sequence in the gene to be expressed is made and inserted into a vessel in the mammal. The polynucleotide is delivered to a cell wherein expression of the gene is inhibited.
摘要:
The present invention relates to methods for delivering a genetic immunogen, comprising a nucleic acid capable of expressing an antigen, optionally complexed with a polymer. The nucleic acid is delivered to the host via hydrodynamic intravascular injection resulting in expression of an encoded antigen in extravascular cells and induction of an antigen-specific immune response.
摘要:
Disclosed is a process for providing for expression of an exogenous nucleic acid in an extravascular parenchymal cell of a mammal. The nucleic acid is inserted into a vessel of a mammal and the permeability of the vessel is increased. Increasing permeability of the vessel allows delivery of the nucleic acid to an extravascular parenchymal cell.
摘要:
A process for delivering a polynucleotide into a parenchymal cell in a mammal, comprising, transporting the polynucleotide into a vessel communicating with the parenchymal cell in tissue or organ of the mammal such that the polynucleotide is transfected into the parenchymal cell. More specifically, the polynucleotide consists of a viral vector.

摘要:
A process for delivering a nucleic acid to a cardiac tissue cell in a mammal is described, comprising introducing a composition consisting of a nucleic acid to a blood vessel, which subsequently delivers the nucleic acid to the cardiac tissue cell. The nucleic acid can be DNA or RNA or plasmid DNA or viral. This process is for purposes of gene therapy, and research.
