摘要:
The present invention provides a method for delivering a pharmaceutical polypeptide to the interior of a cardiac cell of a vertebrate in vivo, comprising the step of introducing a preparation comprising a pharmaceutically acceptable injectable carrier and naked polynucleotide operatively coding for the polypeptide into the interstitial space of the heart, whereby the naked polynucleotide is taken up into the interior of the cell and has a pharmacological effect on the vertebrate. In a preferred embodiment wherein the polynucleotide encodes polypeptide immunologically foreign to the vertebrate, the delivery method preferably comprises delivering an immunosuppressive agent to the vertebrate to limit immune responses directed to the polypeptide.

摘要:
Polynucleotide sequences, comprising DNA and RNA molecules can be directly administered, for example by injection, to tissues, such as muscle, and expressed as a protein, polypeptide or polypeptide. The polynucleotides can be contained within liposomes or the polynucleotides can free from association with transfection-facilitating proteins, viral particles, liposomal formulations, charged lipids and calcium phosphate precipitating agents.
摘要:
A method for delivering an isolated polynucleotide such as DNA or RNA, to the interior of a cell in a mammal comprising the injection of an isolated polynucleotide into a muscle of the mammal where the polynucleotide is taken up by the cells of the muscle and exerts a therapeutic effect on the mammal. The method can be used to deliver a therapeutic polypeptide to the cells of the mammal, to provide an immune response upon in vivo translation of the polynucleotide, to deliver antisense polynucleotides, to deliver receptors to the cells of the mammal or to provide transitory gene therapy.
摘要:
Compounds and methods are provided for a single-step covalent attachment of a label to a molecule comprising forming a covalently attachable labeling reagent for alkylating the molecule. Then, combining the covalently attachable labeling reagent with a mixture containing the molecule, under conditions wherein the labeling reagent has reactivity with the molecule thereby forming a covalent bond.
摘要:
The present invention is directed to membrane active polymers useful for cellular delivery of compounds. Described are polyconjugates systems that incorporate targeting, anti-opsonization, anti-aggregation, and transfection activities into small biocompatible in vivo delivery conjugates. The use of reversible modification provides for physiologically responsive activity modulation.
摘要:
A process for delivering a polynucleotide to a cardiac tissue cell in a mammal is described, comprising introducing a composition consisting of a polynucleotide into a blood vessel and increasing permeability of the blood vessel to the polynucleotide. The polynucleotide can be a small interfering RNA or microRNA and inhibit gene expression in the cell.
摘要:
A process is described for the delivery of a therapeutic polynucleotide to limb muscle tissue suffering from or potentially suffering from Muscular Dystrophy. The polynucleotide is inserted into a mammalian limb vessel such as an artery. Delivery efficiency and distribution is enhanced by combining injection of a solution containing the polynucleotide with the use of an externally applied cuff.
摘要:
Disclosed is a system for providing in vivo delivery of molecules or complexes to extravascular mammalian cells using an intravascular administration route. The molecules or complexes are inserted in an injection solution into a mammalian vasculature. Insertion of the injection solution at an appropriate rate transiently increases the volume of extravascular fluid in the tissue thereby facilitating delivery of the molecule to the cell.
