This image is featured on the poster for Dr. Rommie Amaro's 2017 Stetten Lecture. It depicts a detailed physical model of an influenza virus, incorporating information from several structural data sources. The small molecules around the virus are sialic acid molecules. The virus binds to and cleaves sialic acid as it enters and exits host cells. Researchers are building these highly detailed molecular scale models of different biomedical systems and then “bringing them to life” with physics-based methods, either molecular or Brownian dynamics simulations, to understand the structural dynamics of the systems and their complex interactions with drug or substrate molecules.
