ACE2 and infection: Coronavirus was named so because of the crownlike appearance in the electron microscope, which is attributed to the spike glycoprotein that radiates from the viral surface like a solar corona.4 The spike glycoprotein (S) consists of two subunits, the SI subunit helping the virus bind with the Angiotensin-Converting Enzyme-2 (ACE2) receptor, present on the surface of type 2 pneumocyte in lung and S2 subunit helping in cellular fusion.4,5 So, targeting spike glycoprotein can neutralize the infection by the virus.
