摘要:
The invention relates to a process for the preparation of a product comprising one or more nanoparticles of calcium phosphate (CaP-NP) with negative surface charge having a ζ-potential in the range from -41.0 mV to -27.0 mV comprising the steps of: a) maintaining a mixture having a pH in the range from 7 to 10 and comprising an aqueous solution of calcium, an aqueous solution of phosphate and a solution of citrate ions at a temperature in the range from 20 °C to 40 °C for a time in the range from 30 seconds to 10 minutes; b) removing non-reacted ions from the solution of step a), thus obtaining a suspension of one or more nanoparticles of calcium phosphate (CaP-NP); c) recovering the product of one or more nanoparticles of calcium phosphate (CaP-NP) from the suspension of step b). In an advantageous embodiment, the process of the invention provides, in the mixture of step a), also an aqueous solution of one or more therapeutic/diagnostic compounds. The product of the invention may be used as a vehicle for one or more diagnostic/therapeutic compounds for the treatment of cardiovascular diseases through inhalation administration.
摘要:
The invention provides for double stranded nucleic acid molecules comprising a 5 'extension of the sense or antisense strand and further comprising a plurality of nucleotides that are conjugated to a ligand and methods of using the double-stranded nucleic acid molecules. Ligand-modified oligomers where the sense stands form a tetraloop provide new potent and stable RNA interference agents. These dsNA molecules are synthesized using a plurality of nucleotides that include ligand-modified monomers, nucleotide analog monomers, modified nucleotide monomers and the like, using standard nucleotide synthetic methods and systems.

Compositions comprising nanomembrane delivery complexes, methods of generating nanomembrane delivery complexes, and methods of treating or preventing diseases, disorders or conditions therewith.
摘要:
Described herein are compositions and techniques related to generation and therapeutic application of stem cell-derived exosomes. The Inventors have discovered cardiosphere-derived cells (CDCs) and their secreted exosomes mediate such inflammatory processes, by, for example, shifting macrophages away from a proinflammatory M1 phenotype toward M2 healing phenotype. This suggests compositions and techniques for use in both long-term reversal of heart and vascular disease pathology, and protection against such disease progression via modulation of inflammation and immune responses.
摘要:
This disclosure provides pharmaceutical compositions and purified or isolated naturally occurring exosome products that have therapeutic use for treating an unmet medical need. The exosome compositions contain an effective amount of exosomes isolated from a body fluid of a non-diseased subject. The compositions are useful in the treatment of a variety of fibrotic diseases.
摘要:
The invention involves inducing a plurality e.g., 3-50 or more mutations (e.g., any whole number between 3 and 50 or more of mutations, with it noted that in some embodiments there can be up to 16 different RNA(s), e.g., sgRNAs each having its own a promoter, in a vector, such an AAV vector or a lentiviral vector and that when each sgRNA does not have its own promoter, there can be twice to thrice that amount of different RNA(s), e.g., sgRNAs, e.g., 32 or even 48 different guides delivered by one vector) in transgenic Cas9 eukaryotes to model a neuronal disease or disorder. The invention comprehends testing putative treatments with such models, e.g., testing putative chemical compounds that may be pharmaceutically relevant for treatment or gene therapy that may be relevant for treatment, or combinations thereof. The invention allows for the study of genetic diseases and putative treatments to better understand and alleviate a genetic disease or a condition, e.g., autism, autism-spectrum disease or disorder, obsessive compulsive disorder, or psychiatric disorders.
