摘要:
Methods of treating cancer or reducing the incidence of relapse of a cancer in a subject comprising co-administration of Toll-like receptor (TLR) 4 ligand, such as an HMGN1 protein, and a TLR 7 or 8 ligand, and optionally an immune checkpoint inhibitor, to the subject in need of such therapy. The TLR4-mediated immune-stimulating effect is synergistically enhanced by ligands of TLR7 or 8, and the immune checkpoint inhibitor. Also described here is a nanoparticle delivery platform for the co-administration of the TLR 4 ligand and the TLR 7 or 8 ligand.

Provided herein are polymer-stabilized CaP nanoparticle formulations and related methods of manufacture. In certain embodiments, the methods reliably and selectively form nanoparticles with homogenous size, charge, and morphology. The CaP nanoparticles include calcium ions and phosphate ions with an ionic polymer, thereby forming stable hybrid nanoparticles. The CaP nanoparticle formulations include powders, suspensions and injectable pastes. According to various embodiments, the polymer-stabilized CaP nanoparticles may be polycation-stabilized (CaP/polymer(+) nanoparticles) or polyanion-stabilized (CaP/polymer(-) nanoparticles). The CaP/polymer nanoparticles can be freeze-dried and stored for months with no loss of properties or changes to their morphology.
摘要:
There is provided a core-shell particle comprising a core comprising at least one active agent and a method of forming said core-shell particle, wherein said core having ions of an additive surrounding a surface of said core; and an encapsulating shell comprising (i) a polymer and/or (ii) a metal or a semi-metal oxide, phosphate or carbonate. In a preferred embodiment, chondroitin sulphate nanocrystals is first prepared by using pH recrystallization method. Sodium citrate is then added to form citrate ions-capped chondroitin sulphate particles. Poly L-lysine (PLL) and tetramethoxysilane (TMOS) are subsequently added to form a silica shell surrounding the citrate-ions capped chondroitin sulphate particles, and thus forming the claimed core-shell particle. The particles may be used as sustained release formulations in therapy.

A nanocarrier is described loaded with at least one inhibitor of exocytosis and at least one active ingredient. Said nanocarrier is used for medical use, in particular in the treatment of a tumour.
摘要:
A nanocarrier including a silica body having a surface and defining a plurality of pores that are suitable to receive molecules therein is described. The nanocarrier also includes a lipid bilayer coating the surface, and a cargo-trapping agent within the phospholipid bilayer. The phospholipid bilayer stably seals the plurality of pores. The cargo-trapping reagent can be selected to interact with a desired cargo, such as a drug.
摘要:
Disclosed are methods and compositions for selectively targeting sites of traumatic brain injury (TBI). A brain injury-specific 4-amino acid peptide (sequence CAQK), identified by in vivo phage display screening in mice with acute brain injury, shows selective binding to mouse and human brain injury lesions, and when systemically injected, specifically homes to sites of injury in penetrating and non-penetrating (controlled cortical impact) brain injury models. Also disclosed are methods and compositions for delivering therapeutic compounds to such sites. CAQK-coated nanoparticles containing silencing oligonucleotides provide an alternative to local delivery of therapeutics, which is invasive and can add complications to the injury.

The invention is directed to a method for manufacturing a negatively charged supported lipid bilayer. Said method comprises the steps of preparing a formulation comprising at least three lipids (1,2-dioleoyl-sn-glycero-3-phospho-L- serine (DOPS), cholesterol and at least one lipid different from DOPS and cholesterol) dissolved in a first solvent, of evaporating said first solvent, of adding an aqueous formulation of mesoporous silica nanoparticles, of performing an ultra- sonication and of performing a centrifugation. Said method is remarkable in that the number of equivalents of cholesterol relative to one equivalent of DOPS is comprised between 2.30 and 2.70. The invention is further directed to negatively charged supported lipid bilayer on a mesoporous silica nanoparticle comprising cholesterol, 1,2-dioleoyl-sn-glycero-3-phospho-L-serine (DOPS) and at least one lipid different from DOPS and cholesterol.
摘要:
Disclosed herein are nanoparticles comprising an inorganic material having pores that can quickly absorb pharmaceutical moieties and then release such moieites in a controlled fashion for an extended period of time. The nanoparticles can be aggregated in order to form microaggregates that provide the same advantages of quick absorption and controlled release of pharmaceutical moieties. Quick absorption permits the preparation of drug-loaded nanoparticles and microaggregates essentially contemporaneously with the time of treatment, such as during a surgical process. Methods of preparing such nanoparticles and microaggregates are also provided, as are methods for administering a pharmaceutical moiety using the nanoparticles and microaggregates.
