BSG and COVID-19: CD147 is expressed in numerous cell types, including hematopoietic cells, and exerts pleiotropic functions by interacting with various binding partners, such as the cyclophilin A also involved in COVID-19 [24,28,29,30,31,32] and the monocarboxylate transporter (MCT4), a potential candidate for antiviral drug target to inhibit the replication of SARS-CoV-2 into host cells [33,34].
