摘要:
Lipid nanoparticles having lamellar morphologies are provided. Use of the lipid nanoparticles for delivery of a therapeutic agent and methods for their preparation are also provided.
摘要:
The present disclosure generally relates to poly (lactic-co-glycolic acid)(PLGA) spherical nucleic acids (SNAs) having enhanced stability, methods of making the same, and uses thereof. PLGA-SNAs are useful in gene regulation and drug delivery.
摘要:
The present disclosure relates to materials and methods for extracellular vesicle (e.g. , exosome) -mediated delivery of cargo ( e.g. , endogenous and/or exogenous) to non-bovine mammalian ( e.g. , human) cells. For example, exosomes isolated from bovine milk for delivering cargo to non-bovine mammalian ( e.g. , human) cells are provided.
摘要:
A transfection reagent composition comprising: 30-60 MOL.% of a cationic lipid, or a pharmaceutical acceptable salt thereof; 10-60 MOL% of a structural lipid; 10-20 MOL% of a triglyceride; and 0.1 to about 10 MOL.% of a stabilizing agent, is provided. The transfection agent is effective in transfecting cells, particularly neurons, with siRNA, mRNA and plasmid nucleic acid, and maintaining viability of the cells as well as activity of the delivered nucleic acid.
摘要:
The present invention describes a method for increasing transfection efficiency of cells. The present invention further provides a method for increasing the efficiency of stem cell reprogramming.
摘要:
Methods and compositions for transfecting cells with plasmids are disclosed. In certain embodiments, methods and compositions are disclosed in which transfection efficiency is significantly increased by contacting the cells being transduced with polyethyleneimine (PEI) that is free of nucleic acid during the transfection process. Therapeutically useful adeno-associated viral vectors generated according to the disclosed methods and compositions are also disclosed.
摘要:
The invention relates to nucleic acid vectors comprising a non-mammalian origin of replication and the ability to hold at least 25 kilobases (kb) of DNA, characterized in that said nucleic acid vector comprises retroviral nucleic acid sequences encoding: gag and pol proteins, and an env protein or a functional substitute thereof. The invention also relates to uses and methods of transient transfection using said nucleic acid vector.
摘要:
Lipoplex formulations and uses thereof. In particular, the lipoplexes include at least one naturally-occurring cationic amphiphile, at least one C18-30 saturated fatty acid, cholesterol, at least one nucleic acid, and have a low charge ratio. The lipoplexes are useful for in vivo or in vitro delivery of one or more agents (e.g., a polyanionic therapeutic or an antisense therapeutic, such as an RNAi agent) and allow prolonged expression of these agents, which may be distributed via endogenous cellular pathways to surrounding cells or tissue.
摘要:
Provided are methods employing BCL-2 for the treatment of VDAC-associated disease, wherein the methods comprise administering to a mammal a Bcl-2 protein in an amount sufficient to inhibit a VDAC-associated disease. The disclosure also provides methods for identifying a Bcl- 2 protein that inhibits a VDAC-associated disease when administered to an animal, as well as methods for increasing the effectiveness of a gene, stem cell and/or vaccine therapy involving the administration of an extracellular Bcl-2 protein, a Bcl-2 family member, and/or a fragment thereof comprising a BH4 domain. The disclosure further provides methods for treating diseases involving administering a Bcl-2 protein to a cell that has been engineered to produce exosomes comprising nucleic acid constructs engineered for selective therapeutic transfection of target cell types.
