Fig. 7From: Nicotine inhibits activation of microglial proton currents via interactions with α7 acetylcholine receptorsNicotine inhibits neurotoxic effect of LPS-activated microglia. The conditioned medium from LPS-activated microglia (LPS–MCM) has neurotoxicity due to inflammatory cytokines. However, LPS–MCM from cells with nicotine (1 μM) pre-treatment significantly restored neuronal cells. **p < 0.01 compared to control. ## p < 0.01 compared to LPS–MCMBack to article page
