Whereas 40,000 new instances have been recognized over the previous seven days, INRAE ​​has developed expertise to dam the motion of the virus from the nasal cavity. If commercialized, the challenge would take the type of drops or a sprig and might 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 companies, the well being authorities nonetheless concern the looks of a brand new variant with the arrival of autumn.

Scientists have due to this fact labored, to enrich the motion of vaccines, on a expertise that blocks the transmission of the virus. This takes the type of a protecting portal behind 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 due to the motion of a protein that blocks your entire 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. So as to block the passage in direction of the lungs in addition to the dissemination of viral particles”, explains Nicolas Meunier, one of many research leaders and member of the virology and immunology unit at INRAE

An infinitely moldable protein for different viruses

If the challenge had been to be marketed, it will take the type of a drop or a sprig within the nostril. This expertise is also efficient on any virus. “If there’s one other type of pandemic, then we’ll take it additional this time. And this expertise could be put to make use of, for the reason that proteins we’ve produced can have very completely different shapes in opposition to one other virus”, specifies Nicolas Meunier.

Earlier than we are able to hope to learn from this expertise in our pharmacies, medical trials should now be carried out on people after assessments on hamsters.
