A cure for the common cold may finally be achieved as a result of a remarkable discovery in a Cambridge laboratory - Science, News
The discovery opens the door to the development of a new class of antiviral drugs that work by enhancing this natural virus-killing machinery of the cell. Scientists believe the first clinical trials of new drugs based on the findings could begin within two to five years. The researchers said that many other viruses responsible for a range of diseases could also be targeted by the new approach. They include the norovirus, which causes winter vomiting, and rotavirus, which results in severe diarrhoea and kills thousands of children in developing countries. Viruses are still mankind's biggest killers, responsible for twice as many deaths as cancer, essentially because they can get inside cells where they can hide away from the body's immune defences and the powerful antibiotic drugs that have proved invaluable against bacterial infections. "In any immunology textbook you will read that once a virus makes it into a cell, that is game over because the cell is now infected.
