Abstract: The present disclosure relates to protocells that are useful in the treatment and prevention of viral infections, including but not limited to infections caused by a Hendra virus and Nipah virus (NiV). The present disclosure relates to protocells that are useful in the treatment of bacterial infections, including antibiotic-resistant bacterial infections. The protocells are coated with a lipid bi- or multilayer comprising at least one moiety that targets a viral cellular receptor and at least one moiety that ruptures a virally-infected cell membrane. The present disclosure further relates to novel mesoporous metal oxide nanoparticles and related protocells that are useful in the treatment and/or prevention of a wide variety of disorders, including a cancer or a bacterial or viral infection. Such nanoparticles and protocells can be functionalized to allow for synergistic loading of a wide variety of active ingredients.

Abstract: The present invention is directed to protocells, which have a core and a lipid bilayer surrounding the core, with at least one CD47 molecule or an active fragment thereof in or conjugated to the lipid bilayer. The CD47 present on the lipid bilayer allows the protocell to evade phagocytosis by macrophages, and can be conjugated to the lipid bilayer via a crosslinker. The protocell can be loaded with a diagnostic or therapeutic cargo, such as a polypeptide, a nucleic acid, or a drug. The protocell can also include a targeting species for targeted delivery of the cargo to a cell. The protocell can also include an endosomolytic peptide, which promotes endosomal escape after uptake by the targeted cell. The protocells with CD47 on the lipid bilayer provide better circulation after in vivo administration compared to protocells without CD47, and are therefore particularly useful as a cargo delivery vehicle.

Abstract: The present disclosure relates to the delivery of polynucleotides and/or oligonucleotides using silica delivery platforms, e.g., silica carriers or protocells. In particular, in the present disclosure, polynucleotides in the form of plasmids expressing siRNA may be administered as cargo in the silica delivery platform to a patient or subject to inhibit and/or treat cancer in a patient. In one aspect, the silica delivery platform that have been charged with cargo comprising plasmid DNA (in particular, CRISPR ds plasmid DNA) which expresses siRNA, shRNA, mRNA and other RNA which may be used to administer these plasmids to patients in order to effect inhibition of cancer cells (especially including apoptosis of those cancer cells) and effective and/or prophylaxis of cancer, as well as numerous pathogens, including viruses, bacteria, fungi, and/or other disease states and/or conditions. In another aspect, the silica delivery platform comprises a biological package (e.g.

Abstract: Various embodiments provide materials and methods for synthesizing protocells for use in targeted delivery of cargo components to cancer cells. In one embodiment, the lipid bilayer can be fused to the porous particle core to form a protocell. The lipid bilayer can be modified with targeting ligands or other ligands to achieve targeted delivery of cargo components that are loaded within the protocell to a target cell, e.g., a type of cancer. Shielding materials can be conjugated to the surface of the lipid bilayer to reduce undesired non-specific binding.
