Objective：To investigate the effects of loganin on MPTP-induced autophagy in PC12 cells.
Methods：The autophagy model was established on PC12 cells by neurotoxin 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine（ MPTP）. The expression of autophagy-related factor microtubuleassociated protein1light chain 3-β（ LC3B） in PC12 cells was investigated at different concentrations and different time after MPTP administration. Then，the effects of loganin on the autophagy related signaling pathway induced by MPTP administration in PC12 cells were detected.
Results：LC3B was significantly up-regulated at 12 h after MPTP treatment and the concentration of MPTP at 100 μg·mL-1 showed the strongest action on LC3B expression. Compared to MPTP treated group，the expression of LC3B was significantly down-regulated by loganin at dose of 200 μg·mL-1 combined with MPTP treatment. Furthermore，expression of lysosome associated membrane protein 2 （LAMP-2） was significantly downregulated by loganin at dose of 400 μg·mL-1 combined with MPTP treatment.
Conclusions：MPTP at dose of 100 μg·mL-1 could induce the high expression of autophagy protein at 12 h after treatment. Loganin reduced expression of autophagosomes induced by MPTP in PC12 cells，and the inhibitory mechanism may be related to its enhancing digestion of lysosomes to autophagosomes.
