LONDON, August 23 (SPIS MedWire). Decoy cells that are able to keep viruses away from human cells could help prevent infection. Researchers at the Center for Biologic Technology at the University of Michigan, USA, have created the artificial cells called nanodecoys. The cells are covered in sialic receptors that are able to bind viruses, thereby locking them and preventing them from replicating. Dr Donald Tomalia, Scientific Director, reported their findings at a meeting of the American Chemical Society in Washington DC this week. Dr Tomalia pointed out that nanodecoys have a theoretical advantage over other treatments because they are able to combat the virus before infection occurs. So far, the nanodecoys have inhibited one particular virus from infecting human cells in the test tube, and trials in mice are to begin shortly. One problem that the team has faced is creating a non-toxic polymer to which the sialic...
