Medicine 01

A novel broad spectrum antiviral approach, DRACO, acronym for Double-stranded RNA Activated Caspase Oligomerizer has been developed by the researchers from Lincoln laboratory, MIT, USA. The work was published online in the Journal PLoS ONE. According to the study, DRACO, having two domains- one for binding to viral double stranded RNA (dsRNA) and another for inducing apoptosis when two or more DRACOs crosslink on the same dsRNA, are able to selectively induce apoptosis in cells containing viral dsRNA. This allows the killing of only infected cells without harming the healthy cells.
