Covid symptoms appear in 2 days after virus exposure: Study
London: A team of researchers has identified a protein that may critically contribute to severe forms of Covid-19.
The research, published in the journal Current Issues in Molecular Biology, found that the infection of cells with SARS-CoV-2 results in increased levels of a protein called CD47 on the cell surface.
CD47 is a so-called 'do not eat me' signal to the immune system's defences that protect cells from being destroyed.
Virus-induced CD47 on the surface of infected cells is likely to protect them from immune system recognition, enabling the production of larger amounts of virus, resulting in more severe disease.
