Salk researchers and collaborators show how the protein damages cells, confirming COVID-19 as a primarily vascular disease
LA JOLLA—Scientists have known for a while that SARS-CoV-2’s distinctive “spike” proteins help the virus infect its host by latching on to healthy cells. Now, a major new study shows that the virus spike proteins (which behave very differently than those safely encoded by vaccines) also play a key role in the disease itself.
The paper, published on April 30, 2021, in Circulation Research, also shows conclusively that COVID-19 is a vascular disease, demonstrating exactly how the SARS-CoV-2 virus damages and attacks the vascular system on a cellular level. The findings help explain COVID-19’s wide variety of seemingly unconnected complications, and could open the door for new research into more effective therapies.
“A lot of people think of it as a respiratory disease, but it’s really a vascular disease,” says Assistant Research Professor Uri Manor, who is co-senior author of the study. “That could explain why some people have strokes, and why some people have issues in other parts of the body. The commonality between them is that they all have vascular underpinnings.”
