Rapamycin aggravates the autophagic reaction induced by CVB3 infection. HeLa cells were treated with 10 nM rapamycin and chloroquine phosphate (CQ group) for 2 h. The cells were washed thrice and infected with CVB3. In the CVB3 group, HeLa cells were incubated with DMEM containing 10% FBS for 2 h and infected with CVB3. The sham group was incubated with DMEM containing 10% FBS. Two hours later, the medium was refreshed with DMEM containing 2% FBS. At 24 h.p.i., cells were collected for western blot analysis. The LC3-II/LC3-I ratio was increased in the CVB3 and rapamycin group (p<0.01), and p-mTOR was decreased in the CVB3 group (p<0.05) and rapamycin group (p<0.01) compared with the sham group. The changes in the LC3-II/LC3-I ratio and p-mTOR were more obvious in the Rap group compared with the CVB3 group (p<0.05). The LC3-II/LC3-I ratio and p62 was increased in the CQ group compared with the CVB3 group (p<0.05). *p<0.05, compared with the sham group; **p<0.01, compared with the sham group; #p<0.05, compared with the CVB3 group. CVB3, coxsackievirus B3; DMEM, Dulbecco's modified Eagle's medium; FBS, fetal bovine serum; h.p.i., hours post-inoculation; LC3, light chain 3; mTOR, mammalian target of rapamycin.
