Thalidomide Analogs that Inhibit Inflammation and Angiogenesis

Thalidomide and its close analogs (lenalidomide and pomalidomide) are widely used to treat a variety of diseases, such as multiple myeloma and other cancers as well as the symptoms of several inflammatory disorders. However, thalidomide is known for its teratogenic adverse effects when first clinically introduced in the 1950s, and is associated with drowsiness and peripheral neuropathy. Hence, there is intense interest to synthesize, identify and develop safer analogs. 

Novel Anti-HIV Proteins from Coral Reefs

Scientists at the National Cancer Institute's Molecular Targets Laboratory have discovered that Cnidarins as a novel class of highly potent proteins capable of blocking the HIV virus from penetrating T-cells. Cnidarins were found in a soft coral collected in waters off Australia's northern coast. Cnidarins can block virus fusion/entry but do not block viral attachment. In addition, Cnidarins do not have lectin-like activity and therefore possibly a unique mechanism of action.

Multifunctional RNA Nanoparticles as Cancer and HIV Therapeutics

The promise of RNA interference based therapeutics is made evident by the recent surge of biotechnological drug companies that pursue such therapies and their progression into human clinical trials. The present invention discloses novel RNA  and RNA/DNA nanoparticles including  multiple siRNAs, RNA aptamers, fluorescent dyes, and proteins. These RNA nanoparticles are useful for various nanotechnological applications.

Novel Immunotherapy for Cancer Treatment: Chimeric Antigen Receptors Targeting CD70 Antigen

Scientists at the NCI's Surgery Branch have developed anti-CD70 chimeric antigen receptors (CARs) to treat cancers. CD70 is an antigen that is expressed on a variety of human cancers such as renal cell carcinoma, glioblastoma, non-Hodgkin's lymphoma, and chronic lymphocytic leukemia. The anti-CD70 CARs are hybrid proteins consisting of a receptor portion that recognizes CD70 antigen, and intracellular T cell signaling domains selected to optimally activate the CAR expressing T cells.

Cancer Therapeutic based on Stimulation of Natural Killer T-cell Anti-tumor Activity

Natural killer T cells (NKT) are a unique lymphocyte population that has T-cell and NK cell functional properties in order to rapidly elicit an immune response.  alpha-galactosylceramide (alpha-GalCer) is a potent NKT stimulator and induces of IFN-gamma release to promote immunity against tumors and infectious agents.  Humans have natural antibodies against alpha-galactose, which may be one of the reasons why the human clinical trials of alpha-GalCer or KRN7000 were not very successful.
