(24/7 News) Researchers at Arizona State University's Biodesign Institute are key players in the fight against the Ebola epidemic.  

Department head Charles Arntzen says using tobacco in creating the experimental treatment made perfect sense.

Arntzen says the treatment was developed by companies in California and Kentucky, but it was based on research done at ASU.  

He says it has not been approved by the FDA, but he's glad somebody took a risk and offered it to the Christian missionaries infected with Ebola in West Africa.  Dr. Kent Brantly and Nancy Writebol are now undergoing additional treatment in the U.S. and have reportedly seen their health improve.  Arntzen says he and his colleagues have been working on a vaccine for the deadly virus.
