Methods for Amelioration and Treatment of Pathogen-Associated Inflammatory Response

Description of Technology: This CDC invention provides methods for preventing or treating inflammatory response-linked, infection induced pathologies, which are mediated by endogenous substance P. Substance P is a naturally-occurring and major pro-inflammatory neuromediator or neuromodulator, and elevated levels of substance P have been implicated in numerous inflammation-associated diseases. More specifically, this technology entails administration of anti-substance P antibodies or anti-substance P antibody fragments to a subject in need, thereby inhibiting the activity of endogenous substance P.

Small molecule anti-inflammatory agents currently employed to treat inflammation frequently cause adverse side effects, such as gastrointestinal discomfort and decreased blood clotting efficiency. Use of steroid-based anti-inflammatory drugs may result in reduced adrenal gland function and generalized immune system inhibition. This technology specifically targets and alleviates substance P-induced hyper-inflammatory diseases, potentially avoiding the complications associated with other anti-inflammatory compounds. Blocking the activity of endogenous substance P potentially can be employed to prevent or treat a wide variety of diseases or syndromes caused in whole or part by an inflammatory response mediated by substance P. These include, but are not limited to, virus-mediated bronchiolitis including that mediated by respiratory syncytial virus, bacterial colitis, inflammation associated with chlamydial diseases, lung injury associated with staphylococcal enterotoxin B, inflammation due to cytomegalovirus or hepatitis B virus, sepsis, allergic diseases such as asthma, autoimmune diseases such as rheumatoid arthritis, pancreatitis, inflammatory bowel disease, inflammation associated with multiple sclerosis, and rejection of allografts and other transplanted tissues or organs.

Potential Commercial Applications:

  • Treatment of pathogen induced inflammation, especially bronchiolitis
  • Prevention or lessening of adverse effects associated with other anti-inflammatory agents
  • Amelioration of pain

Competitive Advantages:

  • Useful for management of numerous inflammatory-related viral and/or bacterial infections
  • May reduce or circumvent adverse side effects associated with other small-molecule and/or steroid-based anti-inflammatory treatments

Development Stage:

  • In vitro data available
  • In vivo data available (animal)

Recombinant Sulfated HIV Envelope Protein and Methods for Making Protein

Description of Technology: This technology comprises sulfated recombinant gp120 proteins and peptides. Also included are methods for producing sulfated recombinant gp120 proteins. The focus of this technology is on sulfation of two tyrosines in the V2 loop of the HIV major envelope glycoprotein, gp120, which increase the stability of gp120 and promote the synthesis of gp120 protein in its native “closed” conformation. Gp120 in its native form is highly sulfated; however, recombinant gp120 produced for vaccines or structural analyses typically display low levels of V2 tyrosine sulfation. Sulfation of the V2 loop results in increased binding to trimer-recognizing anti-HIV antibodies specific to the V2 loop region of gp120 (PG9, PG16, CH01, PGT145) and decreased binding of CD4. The sulfation of recombinant gp120 is accomplished by over expression of a tyrosyl sulfotransferase in the producing cell line. Preliminary experiments indicate the recombinant sulfated gp120 proteins can be used to elicit the formation of HIV neutralizing antibodies in immunized animals.

Potential Commercial Applications:

  • Design of HIV vaccines
  • Production of HIV vaccines
  • Induction of Neutralizing Antibodies
  • HIV vaccine booster protein

Competitive Advantages:

  • Consistent sulfation/production of gp120
  • Gp120 vaccine component with improved stability and immunogenicity
  • Recombinant gp120 vaccine component in native conformation

Development Stage:

  • Early-stage
  • In vitro data available
  • In vivo data available (animal)
  • Prototype

Novel Host Target for Treatment of Hepatitis C Virus Infection

Description of Technology: The subject technology is a newly discovered Interferon-lambda 4 (IFNL4) protein found through analysis of genomic data derived from primary human hepatocytes, molecular cloning and functional annotation. The IFNL4 protein is related to but distinct from other known IFNs and its expression is inducible in conditions that mimic viral infection. Preliminary studies indicate that this protein may play a role in impaired natural and treatment induced clearance of HCV. These findings suggest that the protein can potentially be a new target for treating HCV infection.

Potential Commercial Applications:

  • Novel target for treatment of HCV infection.
  • Diagnostics can be developed for detection of IFNL4 mRNA or protein.
  • Existing biological reagents for detection of IFNL4—expression assays, antibodies and protein.

Competitive Advantages: IFNL4 is created by a genetic variant IFNL4-deltaG, which is present only in a subset of individuals, suggesting that IFNL4 is not an essential protein and its functional inactivation may be well-tolerated.

Development Stage:

  • Early-stage
  • Pre-clinical
  • In vitro data available

Knockout Mouse Models for Study of Cholesterol Biosynthesis and Metabolic Diseases

Description of Technology: The farnesoid X receptor (FXR), also known as the bile acid receptor (BAR), is expressed in high levels in the liver and intestine, and controls the synthesis and transport of bile acids, which are degradation products of cholesterol. As such, FXR is a potential drug target for a number of metabolic disorders, such as dyslipidemia, diabetes and atherosclerosis.

Available for licensing are mouse models with a total deletion of the FXR gene (FXR-null mouse), as well as mice with tissue-specific deletions of the FXR gene in the liver or in the intestine. These mice may be useful for the study of cholesterol and bile acid synthesis and their role in metabolic disease, as well as for the development of drugs targeting FXR.

Potential Commercial Applications:

  • Development of FXR/BAR-based drugs for the treatment of cholesterol Start Printed Page 10539disorders and metabolic diseases including dyslipidemia, diabetes and atherosclerosis.
  • Study of the role of FXR in cholesterol biosynthesis and metabolic disease.

Development Stage: Early-stage
