To further test the roles of PSGL-1 and SCARB2 in EV-A71 infection of Jurkat cells, we examined the replication of EV-A71-EGFP, a PSGL-1–binding isolate (SK-EV006 [39]) engineered to express enhanced green fluorescent protein (EGFP) in infected cells, which had been used in the previous study [9] (Fig 4B). Here, SELPLG is linked to infection.
