Receptors should be similar Virologist, Doctor of Biological Sciences Alexei Agranovsky commented on the statement of Chinese colleagues that the coronavirus first originated in mice and then was transmitted to humans. Discuss
The Russian expert doubted this possibility and emphasized that certain conditions are required for the transmission of the virus between different biological species. Therefore, it is more likely that the coronavirus appeared among humans and gained many mutations.
According to Agranovsky, the possibility of transmitting the virus depends on the structure of the receptors – on how similar they are in humans and animals. But the biological source of the origin of the coronavirus – SARS-CoV-2 – has not yet been precisely determined. And for SARS-CoV-1, the causative agent of SARS, it was found that these are bats and Himalayan civets. For the Middle East Respiratory Syndrome (MERS) virus, these are camels,” said Alexey Agranovsky.
