Drug to Cure the Common Cold is Being Developed
UK scientists believe they may have found a way to combat the common cold. Rather than attacking the virus itself, which comes in hundreds of versions, the treatment targets the human host. It blocks a key protein in the body’s cells that cold viruses normally hijack to self-replicate and spread. This should stop any cold virus in its tracks if given early enough, lab studies suggest. Safety trials in people could start within two years.
The Imperial College London researchers are working on making a form of the drug that can be inhaled, to reduce the chance of side-effects. All strains of cold virus need this human protein to make new copies of themselves.
Researcher Prof Ed Tate said, “The idea is that we could give it to someone when they first become infected and it would stop the virus being able to replicate and spread.”
“Even if the cold has taken hold, it still might help lessen the symptoms. This could be really helpful for people with health conditions like asthma, who can get quite ill when they catch a cold.”
He said targeting the host rather than the infection was “a bit radical” but made sense because the viral target was such a tricky one.
Cold viruses are not only plentiful and diverse, they also evolve rapidly, meaning they can quickly develop resistance to drugs. The test drug completely blocked several strains of cold virus without appearing to harm the human cells in the lab. Further studies are needed to make sure it is not toxic in the body though.
Dr Peter Barlow of the British Society for Immunology said, “While this study was conducted entirely in vitro – using cells to model Rhinovirus infection in the laboratory – it shows great promise in terms of eventually developing a drug treatment to combat the effects of this virus in patients.”Disclaimer:We do not allow users to post content which is copyright and We take strict actions against the users who post infringement content on our website.Although we do not host any content, users post embed videos from youtube, facebook, Dailymotion and Vimeo and are moderated before posting but we still take strict action against the copyright videos posted.If you are an official representative of any company whose videos are posted illegally on our website or you think some video infringe the copyright then you can simply send an email to firstname.lastname@example.org
