Combination therapy of a cancer with a multi-specific binding protein that bind a tumor associated antigen, the NKG2D receptor, and CD16, in combination with a second anti-cancer agent are described. Also described are pharmaceutical compositions of the multi-specific binding protein, and therapeutic methods useful for the treatment of cancer in combination with a second anti-cancer agent.

The present invention pertains to a new nanoparticle-like delivery system for intracellular delivery of cargo molecules such as nucleic acids, ribonucleoproteins and extracellular vesicles.

The present invention provides a recombinant exosome comprising a membrane-bound EGF protein on the surface of the recombinant exosome and provides a use of the recombinant exosome.

The present invention provides a recombinant exosome comprising a membrane-bound EGF protein on the surface of the recombinant exosome and provides a use of the recombinant exosome.

Disclosed are agents that include a flavanol (e.g., epigallocatechin-3-gallate) or a flavanol analog, a linker coupled to the flavanol or the flavanol analog, and a carrier (e.g., iron oxide nanoparticle) coupled to the linker. The disclosed agents can be used in methods for destabilizing a tau amyloid fibril, and for treating a tauopathy (e.g., Alzheimer's disease, progressive supranuclear palsy) in a subject.

The present invention relates to biodegradable polyethylene glycol based water-insoluble hydrogels comprising backbone moieties which are interconnected by hydrolytically degradable bonds, the backbone moieties further comprising reactive functional groups, wherein the water-insoluble hydrogel is further characterized in that the ratio between the time period for the complete degradation of the hydrogel by hydrolysis of the degradable bonds into water-soluble degradation products comprising one or more backbone moieties and the time period for the release of the first 10 mol-% of water-soluble degradation products comprising one or more backbone moieties based on the total amount of backbone moieties in the hydrogel is greater than 1 and equal to or less than 2. The invention further relates to conjugates of such hydrogels with ligands or ligating groups, prodrugs and pharmaceutical compositions as well as their use in a medicament.

Methods, systems, compositions and strategies for the use of ARMM-mediated delivery of molecules (e.g., biological molecules, small molecules, proteins, and nucleic acids (e.g., DNA, RNA), DNA plasmids shRNA, mRNA) to cells of the nervous system (e.g., central nervous system and peripheral nervous system).

Compositions comprising donor cells, acceptor cells, membrane-enclosed bodies and methods are described herein.

This disclosure provides compositions and methods for delivering a viral composition to cells, e.g., for cell surface receptor-mediated uptake, and enhanced viral transduction. Viral transduction can be achieved via a bifunctional bridging composition that includes a moiety that binds to a cell surface receptor ligand and a linked bridging moiety that binds to a viral composition. Also provided are modified viral compositions comprising a bridging composition specifically bound via its bridging moiety to the viral composition. Modified viral compositions and methods for reducing levels or titers of neutralizing antibodies in a subject in need of viral therapy, e.g., gene therapy, are provided. In some embodiments, the modified viral composition includes empty viral particles that bind and internalize neutralizing autoantibodies. Modified viral compositions including empty viral particles can be administered prior to viral therapy. Also provided are pharmaceutical compositions and kits including a bifunctional bridging composition and/or modified viral compositions.

A method for preparing a cyclodextrin metal organic framework (CD-MOF) stable in aqueous phase, including: dissolving β-cyclodextrin and solid potassium hydroxide in deionized water followed by magnetic stirring and ultrasonic treatment at room temperature, addition of methanol and stirring to obtain a reaction mixture; filtering the reaction mixture with a polytetrafluoroethylene membrane filter in a beaker; placing the beaker in methanol vapor to form a β-CD-MOF crystal; washing the β-CD-MOF crystal with ethanol followed by centrifugation and vacuum drying to obtain β-CD-MOF; preparing a β-CD-MOF-active substance complex by impregnation; and preparing an active substance-loaded β-CD-MOF-Tween 80 complex by physical adsorption modification followed by washing with anhydrous ethanol and vacuum drying.
