Chikungunya Virus and Receptor (IMAGE) Washington University School of Medicine Caption Researchers at Washington University School of Medicine in St. Louis have created a detailed 3-D structure of chikungunya virus (shown in blue and green) attached to a mouse protein (in magenta) that the virus uses to get inside cells and cause disease. The findings could accelerate efforts to find new ways to prevent or treat viral arthritis.
