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:
We disclose compositions and processes for enhancing transposon mediated integration of a nucleic acid molecule into another target nucleic acid molecule. Integration by an integrator complex is enhanced by cationic reagents.
摘要:
A method is provided for expanding the population of mature dendritic cells in an individual subject. Proper timing of sequential delivery of Flt3-L and GM-CSF provides improved expansion of mature dendritic cell populations over methods currently employed in the art. The expansion of mature dendritic cells can be used to enhance an immune response in the subject. The mature dendritic cells can also be isolated from the subject for use in biological research.

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.
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:
The present invention relates to compositions and methods for increasing long term expression in vitro and in vivo, comprising sequences and gene expression cassettes that increase expression of genes to which they are operably linked.
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.
摘要:
The present invention relates to compositions and methods for transferring nucleic acids into cells in vitro and in vivo. The compositions comprise a transfection reagent and one or more detergents. In preferred embodiments, the compositions comprise delivery systems providing nucleic acid transfer complexes that transfect cells with high efficiency.
