Outline of Final Research Achievements

Enterovirus 71 (EV71) was retrogradely transported in axon of motorneuron in vivo and in vitro. In cultured cells, EV71 was uncoated from 20 to 30 minutes after the infection. The uncoating was observed at vesicles with mannose-6-phosphate receptor (M6PR), Rab9 and lysosome-associated membrane glycoprotein 2 (LAMP2). Furthermore, knockdown experiments showed that M6PR was important for early stage of EV71 infection.
