Whereas 40,000 new instances have been recognized over the previous seven days, INRAE ​​has developed know-how to dam the motion of the virus from the nasal cavity. If commercialized, the undertaking would take the type of drops or a twig and may very well be utilized to any virus.

Covid-19 contaminations are on the rise once more in France. Inside per week, the variety of new instances jumped 55%. If these figures have for the second no consequence on hospital providers, the well being authorities nonetheless worry the looks of a brand new variant with the arrival of autumn.

Scientists have subsequently labored, to enhance the motion of vaccines, on a know-how that blocks the transmission of the virus. This takes the type of a protecting portal in the back of the nostril, historically the gateway for viruses. As quickly because the Covid arrives within the nasal cavities, this portal closes to forestall the virus from infecting us.

All because of the motion of a protein that blocks the complete transmission system of the virus. “One of many methods is to make use of the alpha REP proteins. When the virus arrives within the nostril, it will be unable to connect itself to the cells that it usually infects within the nostril. With a purpose to block the passage in the direction of the lungs in addition to the dissemination of viral particles”, explains Nicolas Meunier, one of many examine leaders and member of the virology and immunology unit at INRAE

An infinitely moldable protein for different viruses

If the undertaking had been to be marketed, it might take the type of a drop or a twig within the nostril. This know-how is also efficient on any virus. “If there’s one other type of pandemic, then we are going to take it additional this time. And this know-how will be put to make use of, for the reason that proteins we’ve got produced can have very totally different shapes in opposition to one other virus”, specifies Nicolas Meunier.

Earlier than we will hope to learn from this know-how in our pharmacies, medical trials should now be carried out on people after exams on hamsters.
