Monoclonal Antibodies That Recognize the Human Type I Interferon Receptor and Block Interferon Signaling

Description of Technology: Type I interferons play a critical role in both innate and adaptive immunity through the stimulation of the IFNAR1 which initiates interferon signaling in response to viral and bacterial infections. However, abnormal interferon signaling is associated with human diseases, such as lupus. The present invention discloses six hybridomas that produce mouse monoclonal antibodies specific for the extracellular domain of human IFNAR1. Two of the monoclonal antibodies are able to bind IFNAR1 and reduce interferon signaling. As such, they can be utilized as a research tool for studying the expression of IFNAR1 and the inhibition of IFNAR1 function in humans or possibly as therapeutic reagents for human diseases.

Potential Commercial Applications:

  • Research reagents for studying the expression and signaling of IFNAR1.
  • A potential therapeutic reagent.

Competitive Advantages:

  • Specific for the extracellular domain of human IFNAR1. Can therefore specifically recognize receptor expressed on the cell surface.
  • Bind IFNAR1 and reduce interferon signaling

Development Stage:

  • Pilot
  • In vitro data available

Method and Platform for Selectively Labeling RNA

Description of Technology: The invention pertains to a three step initiation, elongation and termination method and platform for synthesizing selectively labeled RNA molecules by first polymerizing a first liquid phase RNA molecule from a solid phased DNA template fixed onto a solid phase. The method includes the steps of incubating the solid and liquid phases at appropriate elongation temperatures and then terminating elongation by a separation stage where the phases are incubated at near 0 degrees Celsius where it selectively terminates RNA elongation. The steps can be repeated by the number bases (rNTPs) in the final RNA molecule wherein in each iterative stage a new rNTP can be added that is selectively labeled. The DNA may have a density of 30-80% on the solid substrate, and the solid substrate may be a bead. The bead may comprise a gel, glass, or a synthetic polymer. The bead may have a diameter of 5-100 mm. The concentration of DNA may be 30 mm-1 nm. The concentration of rNTP may be 1-100 times the DNA concentration. The RNA polymerase may be a T7 RNA polymerase. The label may be13 C/5 N,2 H, Cy3, Cy5, a fluorophore, a heavy atom, or a chemical modification.

Potential Commercial Applications: Differentially labeled diagnostics

Competitive Advantages: Multiple use detection method

Development Stage:

  • Prototype
  • In vitro data available

Blood-Based Assay for the Diagnosis and Monitoring of Hyposialylation Disorders

Description of Technology: Sialic acid, a monosaccharide widely distributed in glycoproteins and glycolipids, plays an important role in biological processes such as cellular adhesion, cellular communication and signal transduction. Reduced levels of sialic acid in tissues (also known as hyposialylation) affect the function of muscle, kidney, and other organ systems, and are found in a number of disorders, such as hereditary inclusion body myopathy (HIBM, also known as GNE myopathy), renal hyposialylation disorders, and congenital disorders of glycosylation.

The inventors have developed a sensitive, reliable assay for the diagnosis of hyposialylation disorders that detects a novel glycoprotein biomarker in a patient blood sample. This assay has been validated using samples from patients with GNE myopathy and other hyposialylation disorders. A distinct advantage of this assay is that it is minimally invasive, unlike many currently-available methods for diagnosing hyposialylation disorders, which typically require a tissue biopsy. In particular, this biomarker represents the first non-invasive method for diagnosis of renal hyposialylation.

Potential Commercial Applications:

  • Diagnostic assay to detect hyposialylation
  • Monitoring tool to track patient response to sialylation-increasing therapy

Competitive Advantages: A blood-based assay based on this technology would be less invasive, time-consuming, and costly than a tissue biopsy, which is the current diagnostic standard for hyposialylation disorders, particularly kidney disorders.

Development Stage:

  • Early-stage
  • In vitro data available

Vaccine Adjuvant for Inducing Th17 Focused Response

Description of Technology: Adjuvant selection can be critical to a vaccine's effectiveness. Ideally, an adjuvant will target and activate specific immune pathways to increase the magnitude of a response to the vaccine. A limited range of adjuvants are presently available for human clinical use; these primarily affect T helper cells 1 and 2 (Th1 and Th2). Currently, no adjuvants are approved for human use which primarily affect IL-17-producing T helper cells (Th17) cells. Th17 focused adjuvants may prove critical for developing operative vaccines against pathogens where Th17 activity is essential for protection. This technology relates to novel adjuvants activating either caspase-associated recruitment domain protein 9 (CARD9) or caspase 1 pathways, or a combination of the two; and methods for using these adjuvants for stimulating an immune response. These adjuvants induce Th17 focused stimulation, which may prove essential to development of effective vaccines against a range of pathogens including bacteria and fungi.

Potential Commercial Applications: Vaccine

Competitive Advantages: Th17 skewing adjuvant
