A novel decoy protein designed by Northwestern Medicine scientists fools SARS-Cov-2 by intercepting the spike of the coronavirus and rendering it impotent… The study is the first proof of concept that a soluble human ACE2 protein is effective in vivo in a preclinical study using an appropriate animal model. The soluble ACE2 protein variant developed by Dr. Daniel Batlle, a professor of medicine at Northwestern University Feinberg School of Medicine and a Northwestern Medicine physician, and colleagues binds well to the coronavirus and has been enhanced so it’s effective for days.
