Joan E. Smallshaw has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Ricin A chain mutants lacking enzymatic activity as vaccines to protect against aerosolized ricin
    Patent number: 8323665
    Abstract: The present invention provides methods to produce toxoid vaccines, such as ricin A chain vaccines, with reduced ability to promote vascular leak syndrome (VLS) and catalytic toxicity associated with various proteinaceous toxins, such as ribosome inactivating proteins. The invention also provides toxoids which have been mutated to lack amino acid sequences which induce VLS and toxic catalytic activity.
    Type: Grant
    Filed: February 12, 2007
    Date of Patent: December 4, 2012
    Assignee: The Board of Regents of the University of Texas System
    Inventors: Ellen S. Vitetta, Victor F. Ghetie, Joan E. Smallshaw, Roxana G. Baluna

  • Compositions and methods for modifying toxic effects of proteinaceous compounds
    Patent number: 7452971
    Abstract: The present invention provides methods to produce immunotoxins (ITs) and cytokines with a reduced ability to promote vascular leak syndrome (VLS). The invention also provides ITs and cytokines which have been mutated to lack amino acid sequences which induce VLS.
    Type: Grant
