Explainer: Why COVID-19 is more lethal for patients with heart disease or diabetes

The video explains why COVID-19 patients with heart disease and diabetes are more prone to severe complications. It details how the SARS-CoV-2 virus uses its spike protein to bind to cholesterol, facilitating its entry into cells via ACE2 receptors. The research suggests that blocking the SRB1 receptor can inhibit infection, proposing the use of drugs targeting SRB1 as potential antivirals.

What is the significance of blocking the SRB1 receptor in relation to COVID-19 infection?
