- Interferons are an important part of the immune system’s defence against viruses. Research suggests that SARS-CoV-2-infected cells can make proteins that suppress the production of interferons.…
- In lab experiments with cells and in some people, infection with SARS-CoV-2 is associated with decreased production of proteins called interferons. These proteins help cells resist viral infections…
- SARS-CoV-2 causes no or mild symptoms in most people it infects, but a substantial minority develop symptoms that are serious, including difficulty breathing, cough and, in some cases, pneumonia.
