Poliovirus (PV) can spread through neural pathway to the central nervous system and replicates in motor neurons, which leads to poliomyelitis. Enterovirus 71 (EV71), which is closely related to PV, is one of the causative agents of hand-foot-and-mouth disease and can cause severe neurological diseases similar to poliomyelitis. Since PV is similar to EV71 in its motor neurotoxicity, we tried to understand if the results obtained with PV are of general applicability to EV71 and other viruses with similar characteristics. Using microfluidic devices, we demonstrated that both PV capsid and the PV genome undergo axonal retro-grade transport with human PV receptor (hPVR), and the transported virus replicated in the soma of hPVR-expressing motor neurons. Similar to PV in hPVR-transgenic (Tg) mice, neural pathway ensuring spreading of EV71 has been shown in adult human scavenger receptor class B, member 2 (hSCARB2)-Tg mice. We have validated this finding in microfluidic devices by showing that EV71 is retrogradely transported together with hSCARB2 to the cell body where it replicates in an hSCARB2-dependent manner.(c) 2022 The Authors.
