Abstract:
Objective To determine whether or not enterovirus 71 ( enteroviurs 71, EV71) may induce autophagy and affect the production and release of EV71 after the treatment of autophagy inhibitor. Methods Western blots were performed to examine the conversion of LC3- Ⅰ to LC3-Ⅱ and the degradation of P62 after the RD-A cells were infected with EV71. CCID50 was determined by checking the virus titer in the supernatant of cells that treated with autophagy inhibitor 3-MA. Results EV71 infection enhances the type conversion of LC3 and degradation of P62. The infectious virus particles were decreased after the treatment of 3-MA. Conclusion EV71 infection could induce cell autophagy and the autophagy might contribute to the production and release of infectious EV71 particles.
