Julio Gutierrez

Julio Anacleto Gutierrez is a Mexican-American physician and scientist.

In 2000, Dr. Gutierrez began working at Mount Sinai Hospital, New York with Dr. Andrea Branch studying the hepatitis C virus (HCV). The main focus of their research was to help define the natural history of the novel HCV protein, the Alternate Reading Frame Protein. Additionally, he identified ascitic fluid from HCV patients as a rich source of anti-HCV antibodies, and has been successful in purifying antibodies to HCV proteins that had never been available.
