DRACO - MIT Scientist Develops Vaccine To "Cure All Viral Diseases"

Viral pathogens pose serious health threats worldwide. For clinical viruses such as HIV or hepatitis, emerging viruses such as avian or swine influenza, and highly lethal viruses such as Ebola or smallpox that might be used in bioterrorist attacks, relatively few therapeutics or prophylactics (preventatives) exist. Most therapeutics that do exist are highly specific for one virus, are ineffective against virus strains that become resistant to them, or have adverse effects on patients.

As part of the PANACEA (for Pharmacological Augmentation of Nonspecific Anti-pathogen Cellular Enzymes and Activities) project, researchers from MIT Lincoln Laboratory have developed and demonstrated a novel broad-spectrum antiviral approach, called DRACO (for Double-stranded RNA [dsRNA] Activated Caspase Oligomerizer). DRACO selectively induces apoptosis, or cell suicide, in cells containing any viral dsRNA, rapidly killing infected cells without harming uninfected cells. As a result, DRACO should be effective against virtually all viruses, rapidly terminating a viral infection while minimizing the impact on the patient.

Dr. Todd Rider, senior staff scientist in MIT Lincoln Laboratory’s Chemical, Biological, and Nanoscale Technologies Group, invented PANACEA and the DRACO therapeutics, and led the team that developed them: Scott Wick, in charge of DRACO production; Christina Zook, in charge of cell testing; Tara Boettcher, in charge of mouse trials; and Jennifer Pancoast and Benjamin Zusman, who performed additional experiments.

In work reported in the journal PLoS ONE, DRACO was shown to be effective against all 15 viruses that the team has so far tested in cells, including cold viruses (rhinoviruses), H1N1 influenza strains, adenoviruses, a stomach virus (reovirus), a polio virus, dengue fever virus, and several members of hemorrhagic fever arenavirus and bunyavirus families. DRACO was also demonstrated to be nontoxic in 11 different cell types representing various species (e.g., humans, monkeys, mice) and organ types (e.g., heart, lung, liver, kidney). In addition, experiments demonstrated that DRACO not only is nontoxic to mice but also can save mice infected with a lethal dose of H1N1 influenza. Currently, the team is testing additional viruses in mice and beginning to get promising results with those as well.
