Abstract:
The present invention concerns molecularly imprinted polymers (MIPs) having an affinity for natriuretic peptides, such as atrial natriuretic peptide (ANP). In some embodiments, the MIP is a nanoparticle (a molecularly imprinted polymeric nanoparticle (MIPNP)). Other aspects of the invention include methods of preparing an MIP having affinity for a natriuretic peptide, methods for binding a natriuretic peptide in vitro or in vivo using an MIP of the invention, methods for interfering with the binding of a natriuretic peptide with its receptor in vivo, methods for reducing inflammation, cell growth, cell differentiation, or a cell proliferation disorder, methods for detecting natriuretic peptides, and devices and kits for sequestering and/or detecting natriuretic peptides.
Abstract:
Provided herein is a micelle composition comprising a polyethylene glycol (PEG), a DC-cholesterol, and a dioleoylphosphatidyl-ethanolamine (DOPE) and either or both a pharmaceutical compound core and a polynucleotide coating. Also provided herein is a method of administering one or more compounds to a cell comprising administering to the cell a micelle composition comprising 1) PEG-PE, a DC-cholesterol, and DOPE, and 2) the one or more compounds, wherein the compounds are selected from the group consisting of a polynucleotide and a pharmaceutical composition. Further provided are methods for detecting the micelle composition.
Abstract:
Provided herein is a method of transfecting a brain cell of a subject with a polynucleotide comprising systemically administering to the subject a composition comprising a micelle having a hydrophobic superparamagnetic iron oxide nanoparticle (SPION) core, a first coating comprising a cationic polymer, and a second coating comprising the polynucleotide, wherein the subject has a mild traumatic brain injury.
Abstract:
Provided herein is a three-dimensional scaffold composition comprising randomly oriented fibers, wherein the fibers comprise a polyethylene glycol-polylactic acid block copolymer (PEG-PLA) and a poly(lactic-co-glycolic acid) (PLGA). Also provided are methods for using the three-dimensional scaffolds described herein.
