Some embodiments pertain to nanoparticle-based compositions and their use in methods for the delivery of therapeutic ingredients to subjects. In some embodiments, the compositions are stable for prolonged periods of time and provide enhanced bioavailability.

Provided herein are compositions, systems, and methods for delivering an effector protein into a cell. The present disclosure, in some aspects, provide novel proteins delivering an effector protein into a cell. The novel proteins are supernegatively charged proteins derived from highly anionic proteins identified from the proteome (e.g., human proteome). The novel protein tags can be associated (e.g., covalently or nocovalently) with the protein to be delivered to facilitate delivery of the effector protein into a cell.

The present disclosure relates to antigen presenting cells and uses thereof for treating sepsis. In some aspects, disclosed herein is an antigen presenting cell, comprising: a lipid-based nanoparticle, comprising: a recombinant polynucleotide, comprising: a first nucleic acid encoding an antimicrobial peptide; a second nucleic acid encoding cathepsin B; and a third nucleic acid encoding a linker; and a vitamin-lipid.

Provided herein are lipid compounds that can be used in combination with other lipid components, such as neutral lipids, cholesterol and polymer conjugated lipids, to form lipid nanoparticles for delivery of therapeutic agents (e.g., nucleic acid molecules) for therapeutic or prophylactic purposes, including vaccination. Also provided herein are lipid nanoparticle compositions comprising said lipid compounds.

Disclosed herein compositions of polysaccharides chemically cross-linked by aromatic dialdehydes. The compositions may be in form of polymeric sheets for a variety of applications. Disclosed also nano-sized particles comprising the polysaccharide chemically cross-linked by aromatic dialdehydes. The nano-sized particles may further comprise lipids and surfactants. Intranasal delivery of the nano-sized particles enables delivery of biologically active agents into the brain. Topical and transdermal delivery of the nano-sized particles enables delivery of biologically active agents for treatment of systemic or dermatological disorders. Methods of manufacturing and uses of the compositions are also disclosed.

A dispersion solution contains a complex of cerium oxide nanoparticle with protein in which a hydrodynamic diameter and zeta potential of the protein are maintained. The dispersion solution is produced by mixing a solution containing the protein with a solution containing a cerium (III) ion or with a cerium (III) salt followed by adding an oxidizing agent thereto.

The invention relates to compositions including polynucleotides encoding polypeptides which have been chemically modified by replacing the uridines with 1-methyl-pseudouridine to improve one or more of the stability and/or clearance in tissues, receptor uptake and/or kinetics, cellular access by the compositions, engagement with translational machinery, mRNA half-life, translation efficiency, immune evasion, protein production capacity, secretion efficiency, accessibility to circulation, protein half-life and/or modulation of a cell's status, function, and/or activity.

The disclosure features immune cell delivery lipid nanoparticle (LNP) compositions that allow for enhanced delivery of agents, e.g., nucleic acids, such as therapeutic and/or prophylactic RNAs, to immune cells, in particular T cells, as well as B cells, dendritic cells and monocytes. The LNPs comprise an effective amount of an immune cell delivery potentiating lipid such that delivery of an agent by an immune cell delivery LNP is enhanced as compared to an LNP lacking the immune cell delivery potentiating agent. Methods of using the immune cell delivery LNPs for delivery of agents, e.g., nucleic acid delivery, for protein expression, for modulating immune cell activity and modulating immune responses are also disclosed.

The present invention relates to a nanoparticle or nanoformulation comprising two or more bioactive phytochemicals from turmeric. The nanoparticle or nanoformulation preferably comprises curcumin or curcuminoids and water-soluble peptides comprising turmerin. The waster-soluble peptides comprising turmerin are preferably present in a water-soluble extract of turmeric which comprises turmerin. Methods for producing the nanoparticle or nanoformulation are also disclosed.

A nanoparticulate composition including particles comprising at least one active ingredient, wherein the particles have an effective average particle size is in the range of about 70 nm to about 220 nm measured by laser light scattering method, wherein at least 50% of said active agent particles have a particle size, by weight (volume based), of less than the effective average particle size; and (b) at least one surface stabilizer and/or at least one polymeric stabilizer, wherein the composition includes (aa) particles of at least one active ingredient selected from the group consisting of (Z)-2-cyano-3-cyclopropyl-3-hydroxy-N-(3-methyl-4-(trifluoromethyl)phenyl) prop-2-enamide, (Z)-2-cyano-3-hydroxy-N-[4-(trifluoromethyl)phenyl]hept-2-en-6-ynamide, 2-cyano-3-cyclopropyl-N-(4-fluorophenyl)-3-hydroxyacrylamide, derivatives thereof, salts thereof and pro-drugs thereof, wherein the particles have an effective average particle size of less than about 2000 nm; and (bb) at least one surface stabilizer and/or at least one polymeric stabilizer.
