  • Let's do the twist: Spiral proteins are efficient gene delivery agents

    Illinois researchers developed spiral polypeptides that can deliver DNA segments to cells with high efficiency and relatively low toxicity, a step toward clinical gene therapy. The team, from left, postdoctoral researchers Lichen Yin and Dong Li; Fei Wang, a professor of cell and developmental biology; Jianjun Cheng, a professor of materials science and engineering; and Nathan Gabrielson, a postdoctoral researcher.
