  • Publication number: 20150110825
    Abstract: The present invention provides nanoparticles and compositions of various constructs that combine meta-stable viral proteins (e.g., RSV F protein) and self-assembling molecules (e.g., ferritin, HSPs) such that the pre-fusion conformational state of these key viral proteins is preserved (and locked) along with the protein self-assembling into a polyhedral shape, thereby creating nanoparticles that are effective vaccine agents. The invention also provides nanoparticles comprising a viral fusion protein, or fragment or variant thereof, and a self-assembling molecule, and immunogenic and vaccine compositions including the same.

  • Publication number: 20150099001
    Abstract: Nanocells allow the sequential delivery of two different therapeutic agents with different modes of action or different pharmacokinetics. A nanocell is formed by encapsulating a nanocore with a first agent inside a lipid vesicle containing a second agent. The agent in the outer lipid compartment is released first and may exert its effect before the agent in the nanocore is released. The nanocell delivery system may be formulated in pharmaceutical composition for delivery to patients suffering from diseases such as cancer, inflammatory diseases such as asthma, autoimmune diseases such as rheumatoid arthritis, infectious diseases, and neurological diseases such as epilepsy. In treating cancer, a traditional antineoplastic agent is contained in the outer lipid vesicle of the nanocell, and an antiangiogenic agent is loaded into the nanocore. This arrangement allows the antineoplastic agent to be released first and delivered to the tumor before the tumor's blood supply is cut off by the antianiogenic agent.
