While COVID-19 continues to remain a difficult puzzle for researchers across the world, a new study has suggested that micro clots formed in people with COVID-19 are responsible for long COVID. 

The study published in the Journal of American Chemical Society has shown that amyloids, the abnormal proteins that are linked with the development of Alzheimer’s could be formed following SARA-CoV-2 infection. The research suggested that the interaction of the immune system with SARS-CoV-2 may lead to blood clots and neurological symptoms due to the production of these misfolded spike proteins.

In this study, researchers examined if the spike protein of SARS-CoV-2 could be converted to amyloids in the body. The researchers found that many parts of the S-protein could eventually be converted into amyloids. The researchers explained that if fibrin is formed in the presence of spike amyloid, the plasmin cannot totally remove the fibrin clots. Amyloids are also associated with several other health problems, such as cardiac arrhythmias, atherosclerosis, type 2 diabetes mellitus, and rheumatoid arthritis.
