ACE2-interacting domain of SARS-CoV-2

In a study published in the Journal of Neuroimmune Pharmacology, mouse models with COVID-19 showed positive results when a small peptide was introduced nasally. The peptide proved effective in reducing fever, protecting the lungs, improving heart function and reversing cytokine storm — a condition in which an infection triggers the immune system to flood the bloodstream with inflammatory proteins. The researchers also report success in preventing the disease from progression.

Our neighbor Dr. Arlan Richardson at part of the University of Oklahoma Health Sciences Center knows a lot about mice. I’ll have to ask him what he thinks of the potential of this peptide for human use.
