SCARB2 and infection: Yamayoshi et al. [9] reported high levels of surface-SCARB2 expression on RD and HeLa cells, and lower levels on HEp-2c, 293T, and Hep G2 cells as determined by flow cytometric analysis; they also stated that the levels of SCARB2 at the cell surface correlated with susceptibility of these cell lines to EV-A71 infection [9].
