Researchers find natural metabolites help SARS-CoV-2 escape antibodies

An international team of scientists has identified a human molecule — biliverdin — as a potential severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) target. The binding of the heme metabolite to the N-terminal domain of SARS-CoV-2 is associated with the virus’s ability to dodge the immune system by suppressing antibody binding to the spike protein.
