Small Interfering RNA Knock-Down of Cannabinoid-1 Receptor (CB1R) for the Treatment or Prevention of Type-2 Diabetes

Description of Technology: Endocannabinoids (EC) are lipid signaling molecules that act on the same cannabinoid receptors that recognize and mediate the effects of marijuana. Activation of the EC receptor CB1R has been shown to play a key role in the development of obesity and its metabolic consequences, including insulin resistance and type 2 diabetes. Researchers at NIH have now demonstrated in the Zucker diabetic fatty (ZDF) rat model of type-2 diabetes that beta-cell loss is caused by the CB1R-mediated activation of a macrophage-mediated inflammatory response. They have further demonstrated that treatment of ZDF rats with a peripheral CB1R antagonist restores normoglycemia and preserves beta-cell function and that similar results were seen following selective in vivo knockdown of macrophage CB1R by daily treatment of ZDF rats with D-glucan-encapsulated CB1R Small interfering RNA (siRNA). Therefore, knock-down of CB1R with siRNA may represent a new method of treating type-2 diabetes or preventing the progression of insulin resistance to overt diabetes.

Potential Commercial Applications: Treatment of obesity, insulin resistance, and diabetes.

Competitive Advantages: A new means of inhibiting the endocannabinoid receptor CB1R.

Development Stage: In vivo data available (animal).

Methods for the Treatment of AIDS and Other Retroviral Diseases Using Plant-Derived Compounds

Description of Technology: Human immunodeficiency virus-1 (HIV-1) affects 1.4 million patients in the U.S. and over 33 million worldwide. While highly active antiretroviral therapy (HAART), the current standard of care, is effective in suppressing retroviral activity, cure has not been achieved due to the persistence of latently infected T cells in treated patients. An agent capable of sensitizing this T cell subpopulation concordant with HAART may add significant benefit to individuals with retroviral diseases.

Researchers at the NIH have identified Englerin A and its derivatives as potent and specific activators of viral replication in infected T cells. Use of these compounds in conjunction with existing antiviral therapies has been described for the treatment of AIDS, adult T cell leukemia/lymphoma and other retroviral diseases.

Intellectual property assets available for license include novel compositions of Englerin A along with methods of their use in the treatment of retroviral diseases.

Potential Commercial Applications

  • Novel adjuvant therapy for the treatment of retroviral diseases such as AIDS or HTLV-induced leukemia/lymphoma.
  • Therapeutic for the management of T lymphocytopenia.

Competitive Advantages

  • Englerin A and its derivatives are potent and selective activator of protein kinase C theta in immune cells.
  • Compounds are anticipated to have fewer off-target toxicities relative to currently available PKC activators (e.g., interleukins-2 and 7).
  • Compounds are optimized for use in combination with clinically available antiviral agents.

Development Stage

  • Pre-clinical.
  • In vitro data available.
  • In vivo data available (animal).

Inventors: Leonard Neckers, Marston Lineham, Carole Sourbier, Jane Trepel, Min-jung Lee, Bradley Scroggins, John Beutler (all of NCI).

Development of Immune System Tolerance for the Treatment of Autoimmune Disease

Description of Technology: The present invention provides a therapeutic method for the treatment of autoimmune or autoinflammatory diseases by first breaking down the dysregulated immune system and then reprogramming the immune system to restore tolerance to the patient's self-antigens by induction of antigen specific regulatory T cells. The inventors have shown that only with the combination of apoptosis, phagocytes, and antigen can antigen-specific regulatory T cells (Treg) cells be optimally generated to develop long-term immune tolerance. This strategy for developing immune tolerance can be applied to the treatment of autoimmune diseases.

Potential Commercial Applications: Treatment of autoimmune disease.

Competitive Advantages: This technology represents a novel means of treating autoimmune disease.

Development Stage

  • Early-stage.
  • In vivo data available (animal).
