  • Patent number: 10206976
    Abstract: This disclosure relates to particles comprising recombinant proteins, pharmaceutical composition comprising the particles, and therapeutic uses related thereto. In certain embodiments, the particles are made by the process of producing recombinant proteins and conjugating the recombinant proteins to form nanoparticles with a linking reagent comprising disulfide bonds. Typically the recombinant protein has a polypeptide of viral, fungal, or bacterial origin such as secreted effector proteins AvrA and YopJ. In certain embodiments, the disclosure relates to treating or preventing autoimmune diseases, cancer, or inflammatory diseases, or conditions such as inflammatory bowel disease (IBD).

  • Publication number: 20160158154
    Abstract: Hollow, protein vesicles are provided. The protein vesicles can be loaded with desired cargo to be delivered to a subject, for example a human. One embodiment provides a protein vesicle made of a protein membrane surrounding a hollow core. The protein membrane includes a first and a second modular protein amphiphile. The first modular protein amphiphile includes a hydrophobic block and a first hydrophilic protein binding block. The second modular protein amphiphile includes a variable polypeptide block and a second hydrophilic protein binding block that binds to the first hydrophilic protein binding block. The first and second protein amphiphiles self-assemble to form the hollow, protein vesicle.

  • Publication number: 20100217403
    Abstract: The present invention generally relates to particles comprising hyaluronic acid, wherein the particles are coated or encapsulated with a coating. The coating preferably comprises a polymer, protein, polysaccharide, or combination thereof that decreases the rate of degradation of the hyaluronic acid once the particles are placed in an aqueous environment, such as inside mammalian skin. The compositions of the present invention comprising such coated hyaluronic acid are useful for soft tissue augmentation, and are particularly useful as dermal fillers.

  • Publication number: 20080112886
    Abstract: Compositions containing polymeric micro- and nanoparticles with non-spherical shapes and methods for making and using such particles are described herein. The particles have a size range from an average diameter of about Compositions containing polymeric micro- and nanoparticles with non-spherical shapes and methods for making and using such particles are described herein. The particles have one or more dimensions ranging from about 5 nm to about 100 ?m, preferably about 100 nm to 10 ?m. The particles can have any of a wide variety of non-spherical shapes. The particles are generally formed by manipulation of spherical particles embedded in a polymeric film. A wide variety of resulting shapes can be made. The resulting shape is a function of whether the films are manipulated in a first and/or second dimension, and the processes used to liquefy the microparticles. Variations of the method of manufacture may be used to generate particles having the desired shapes in large, reproducible quantities.
