Snippet: The coronavirus heptide repeat (HR) region in the spike protein induces neutralizing antibodies that block the postfusion core formation and inhibit virus entry into target cells. The HR2 regions for coronaviruses of the same serogroup share high homology. We found that polyclonal antibodies derived from transmissible gastroenteritis coronavirus HR2 and upstream region were cross-reactive with the S proteins of the same serogroup in western blotting. The polyclonal antibodies also potently cross
Document: The coronavirus heptide repeat (HR) region in the spike protein induces neutralizing antibodies that block the postfusion core formation and inhibit virus entry into target cells. The HR2 regions for coronaviruses of the same serogroup share high homology. We found that polyclonal antibodies derived from transmissible gastroenteritis coronavirus HR2 and upstream region were cross-reactive with the S proteins of the same serogroup in western blotting. The polyclonal antibodies also potently cross-neutralized viruses from the same serogroup. This study provides new insight for designing vaccine and therapeutic reagents against coronavirus infections.
