Meth treatment did not upregulate production of proinflammatory cytokines. The transcriptional levels of IL-1β and TNFα were analyzed by qPCR after treatment of Meth on isolated microglia. Effects of different concentrations of Meth were measured with (B, E) or without (A, D) priming signal (100 ng/ml LPS). The potentiation effects of Meth (50 μM) on LPS (100 ng/ml) was also measured at different time points (C).
