Authors: By Dr. Liji Thomas, MD Reviewed by Emily Henderson, B.Sc. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause inflammatory lung disease, including clot formation and hyper-permeability of the lung vessels, resulting in edema and bleeding into the lung. Inflammation also affects other organs, mediated by the cytokine storm. This inflammation is characterized by endothelial cell […]

Salk researchers and collaborators show how the protein damages cells, confirming COVID-19 as a primarily vascular disease April 30, 2021 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 […]

Author: Dr. Charles Hoffe in a Coronavirus, that spike protein becomes part of the viral capsule. In other words, the cell wall around the virus, called the viral capsule. But it’s not in the virus. It’s in your cells. So it therefore becomes part of the cell wall of your vascular endothelium. Which means that […]
