Patents by Inventor Dawn Bowdish

Dawn Bowdish 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: 11577248
    Abstract: A biosensor detector device is disclosed suitable for use in measuring membrane fluidity or membrane permeability. The biosensor detector device is formed of a solid substrate having a lipid bilayer compatible surface, a multi-lamellar lipid membrane structure derived from a biological cell and localized on the lipid bilayer compatible surface, an aqueous layer interposed between each lipid bilayer of the multi-lamellar lipid membrane structure. The biological membrane is derived from human red blood cells and localized on the lipid bilayer compatible surface. An electrode forming all or part of the lipid bilayer compatible surface may be used to detect disruptions in the multi-lamellar lipid membrane structure and hemolytic activity in a test sample.
    Type: Grant
    Filed: December 21, 2018
    Date of Patent: February 14, 2023
    Assignee: McMaster University
    Inventors: Maikel Rheinstadter, Sebastian Himbert, Richard Alsop, Jose Moran-Mirabal, Sokunthearath Saem, Dawn Bowdish

  • Patent number: 7687454
    Abstract: A method of identifying a polynucleotide or pattern of polynucleotides regulated by one or more sepsis or inflammatory inducing agents and inhibited by a peptide is described. A method of identifying a pattern of polynucleotide expression for inhibition of an inflammatory or septic response. The method includes contacting cells with LPS, LTA, CpG DNA and/or intact microbe or microbial components in the presence or absence of a cationic peptide; detecting a pattern of polynucleotide expression for the cells in the presence and absence of the peptide, wherein the pattern in the presence of the peptide represents inhibition of an inflammatory or septic response. Also included are compounds and agents identified by the methods of the invention. In another aspect, the invention provides methods and compounds for enhancing innate immunity in a subject.

  • Publication number: 20070190533
    Abstract: The present invention provides a method of identifying agents that enhance innate immunity in a subject. The invention further provides a method of selectively supresses sepsis by suppressing expression of a proinflammatory gene while maintaining expression of an anti-inflammatory gene. Also provided are methods of identifying a polynucleotide or pattern of polynucleotides regulated by one or more sepsis or inflammatory inducing agents and inhibited by a peptide is described, methods of identifying a pattern of polynucleotide expression for inhibition of an inflammatory or septic response, and compounds and agents identified by the methods of the invention.
