Kaempferol protects against microglial-mediated neurotoxicity. SH-SY5Y cells were treated with conditioned media (CM) from BV2 cells exposed toLPS (1.0 µg·mL−1) with or without kaempferol (10–100 µM) pretreatment for 1 h. After 24 h incubation, the viability of SH-SY5Y cells was assessed by MTT assay. Results are expressed as mean ± SD of three independent experiments. #P < 0.05, compared with control group. *P < 0.05, **P < 0.01, compared with LPS treated alone. Con, control; Kae, kaempferol.
