BSG and infection: Moreover, high-density lipoprotein (HDL) scavenger receptor B type 1 (SR-B1) has been reported to promote SARS-CoV-2 entry, in an ACE2-dependent manner (Wei et al., 2020), whereas the transmembrane glycoprotein CD147 (also named BSG (basigin (Ok blood group) (Kaname et al., 1993) or EMMPRIN (extracellular matrix metalloproteinase inducer) (Biswas et al., 1995)), could mediate viral entry and infection by endocytosis, even in cells lacking ACE2 expression (Wang et al., 2020c).
