A protein in the lungs that blocks Covid and forms a natural barrier to the virus has been discovered by scientists at the University of Sydney.
The naturally occurring protein, LRRC15, works by attaching itself to the virus like Velcro, preventing the Covid particles from binding with more vulnerable cells – as well as reducing the chance of infection.
The astonishing find may finally explain why some people suffer serious illness with the virus, or even death, while others never get sick or appear symptomless.
LRRC15 is not known to be present in humans until the virus enters the body, but it appears after infection.
