In patients with serious and long-term COVID-19, disturbed blood coagulation has often been observed. Now, researchers have discovered that the body's immune system can affect the spike protein on the surface of the SARS-CoV-2 virus, leading to the production of a misfolded spike protein called amyloid. The research team studies illnesses which are caused by misfolded proteins, of which Alzheimer's disease in the brain is the most well-known example. The researchers noted that there are many similarities between COVID-19-related symptoms and those which are observed in illnesses caused by misfolded proteins. Using computer simulation, the researchers discovered that the coronavirus'...
