Blocking Interleukin-6 Proteins (IMAGE) Ohio Supercomputer Center Caption An electrostatic representation (red: negative; blue: positive; white: hydrophobic) created at the Ohio Supercomputer Center by Ohio State’s Chenglong Li, Ph.D., shows IL-6 in ribbon representation. The two larger yellow ellipses indicate the two binding "hot spots" between IL-6 and GP130, key to blocking a protein that plays a role in breast and prostate cancer.
