Cynthia K. BULLEN 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).

  • Patent number: 11965009
    Abstract: The present invention is a DNA expression vector comprising: a toxP: a mutant toxO that blocks Fe-mediated regulation of gene expression; and a DNA sequence encoding a protein, wherein the toxP and the mutant toxO regulate expression of the DNA segment encoding the protein. It is preferred that DNA expression vectors of the present invention include DNA sequences encoding a signal peptide so that a protein expressed is attached to the signal peptide prior to processing. Novel proteins are produced off of the DNA expression vector of the present invention.
    Type: Grant

  • Publication number: 20180169108
    Abstract: Provided herein are effective latency-reversing agent (LRA) combinations of drugs for the reversal of HIV-1 latency. Such methods utilize, for example, the combination of a protein kinase C agonist and a bromodomain inhibitor combine to reverse latency or a NF?B activator combined with histone deacetylase inhibitors to reverse latency. These findings are surprising considering that many of the individual drug in these combinations show no effect alone. Novel drug combinations for reversal of HIV-1 latency/reactivation of latent HIV-1 may include 1) disulfiram (acetaldehyde dehydrogenase inhibitor, activator of NF-?B via AKT signaling) plus histone deacetylase inhibitors or 2) protein kinase C agonists with bromodomain inhibitor JQ1. Latency-reversing drug combinations for use in HIV-1 infected individuals may eliminate the HIV-1 reservoir for cure/long-term drug-free remission.
