His crew believes their receptor decoys will possible be in reality useful in the direction of different coronaviruses that infect cells by technique of the ACE2 receptor, and furthermore, the approach might nicely perchance additionally very neatly be utilized to different cell membrane receptors archaic by different respiratory viruses.
