Interleukin-2 Stimulated T-Lymphocyte Cell Death for the Treatment of Autoimmune Diseases, Allergic Disorders and Graft Rejection

T-cell apoptosis induced by administration of IL-2 and antigen offers an important new treatment for allergic disorders, which are due to the effects of antigen-activated T-cells. Antigen-activated T-cells cause the release of harmful lymphokines and the production of immunoglobulin E by B cells. Presently available methods for treating allergies have limitations because they are nonspecific in their action and have side effects and limited efficacy. IL-2 and antigen stimulates the programmed death of only antigen-specific T-cells while leaving the rest of the patient's T-cells and other immune cells intact. This invention is also useful in treating HIV. Both fields of use, allergies and HIV, are available for licensing.

Potential Commercial Applications: Competitive Advantages:
  • allergies
  • HIV complications
  • precise for a specified antigen
  • does not compromise a patient's immune system
