The application relates to a lipid conjugate of formula M-X1-L wherein M is a molecule of interest such as a drug moiety; X1 is a linker group such as ester, ether or carbamate; and L is a lipid scaffold represented by formula (IId): -L1-[L2(H)(X2R)]n-L3-[L4(H)(X2R)]p-L5-L6 and wherein L comprises 5 to 40 carbon atoms and 0 to 2 carbon-carbon double bonds. The lipid conjugate can p be formulated in a drug delivery vehicle such as a lipid nanoparticle (LNP).

Compositions are described for direct protein delivery into multiple cell types in the mammalian inner ear. The compositions are used to deliver protein(s) (such as gene editing factors) editing of genetic mutations associated with deafness or associated disorders thereof. The delivery of genome editing proteins for gene editing and correction of genetic mutations protect or restore hearing from genetic deafness. Methods of treatment include the intracellular delivery of these molecules to a specific therapeutic target.

Compositions and methods for therapeutic delivery are disclosed. More particularly, the present disclosure relates to nanoparticle compositions that sequester the activity of a target molecule while leaving other domains accessible to bind targeted tissues of interest. Methods for thrombus dissolution include administering a nanoparticle reversibly coupled to a target molecule that can dissolve a blood clot. Compositions and methods for inducing blood clotting are also disclosed. Methods for inducing blood clotting include administering a nanoparticle reversibly coupled to a target molecule that can induce the formation of a blood clot. Methods for sequestering a target molecule are also disclosed. The method includes reversibly coupling a target molecule to a nanoparticle having an affinity ligand that reversibly couples the target molecule, and thus, sequesters the target molecule activity until the target molecule interacts with its substrate resulting in the release of the target molecule.

The present disclosure provides a synthetic nanoparticle comprising a peptide nucleic acid (PNA) oligomer conjugated to a lipid, wherein the PNA oligomer noncovalently complexes with an immunomodulatory compound, thereby forming a nanoparticle. The nanoparticles are useful to elicit immune responses and can be used to treat a broad range of cancers and infectious diseases.

The present disclosure provides nanostructures (e.g., monolayer or bilayer nanostructures) comprising porphyrins with cobalt chelated thereto such that the cobalt metal resides within monolayer or bilayer in the porphyrin macrocycle. The nanostructures can have presentation molecules comprising epitopes from microorganisms with a histidine tag attached thereto, such that at least a part of the his-tag is within the monolayer or bilayer and coordinated to the cobalt metal core and the presentation molecules are exposed to the outside of the nanostructures. The nanostructures can further comprise a cargo. The nanostructures can be used to deliver the cargo to an individual.

The present disclosure provides one or more amino lipids such as an amino lipids containing a sulfonic acid or sulfonic acid derivative of the formulas:

##STR00001##

wherein the variables are as defined herein. These amino lipids may be used in compositions with one or more helper lipids and a nucleic acid therapeutic agent. These compositions may be used to treat a disease or disorder such as cancer, cystic fibrosis, or other genetic diseases.

A method of use for prevention and treatment of COVID-19 using IL13 is described.

The invention represents an advancement in the field of cancer therapeutics and provides for a polymer-protein based thermosensitive hydrogel comprising polyvinyl alcohol, poloxamer 407 and bovine serum albumin. The thermosensitive hydrogel can be optionally be enriched with one or more additional component such as photothermal agents, photosensitizers, drugs and dyes. The invention also provides for a method of preparing the thermosensitive hydrogels. The hydrogels of the present invention are inexpensive, thermosensitive, has ability to effectuate sustained release of drugs and can be used for targeted delivery and dual-modality treatment.

This invention relates to compositions useful for localized and sustained release of therapeutic agents, and more particularly to functionalized liposomes embedded in a polyelectrolyte multilayer. Methods of preparing the compositions, methods of treating diseases, devices, and pharmaceutical compositions comprising the compositions are also provided.

Polynucleotides such as DNA are stored inside vesicles formed from self-assembling membranes. The vesicles may be protocells, liposomes, micelles, colloidosomes, proteinosomes, or coacervates. The vesicles may include surface functionalization to improve polynucleotide encapsulation and/or to bind polynucleotides having specific sequences. Encapsulation in vesicles provides protection for the polynucleotides. Additional protection is provided by addition of one or more stabilizers. The stabilizer may be nucleic-acid stabilizers that stabilize the polynucleotides or may be a protective structural layer around the vesicles such as a layer of silica. A process for stably storing polynucleotides in vesicles and a process for recovering stored polynucleotides from vesicles are both disclosed. The polynucleotides may be used for storage of digital information.
