Fig. 7From: Histamine 2/3 receptor agonists alleviate perioperative neurocognitive disorders by inhibiting microglia activation through the PI3K/AKT/FoxO1 pathway in aged ratsAn agonist of H2R or H3R inhibits LPS-induced microglia migration. a The migration ability of primary microglia was tested by transwell assay. Scale bar = 20 μm. b Quantification of primary microglia transmitted to the lower surface of the membrane. **P < 0.01 versus the control group. #P < 0.05 versus the LPS group (n = 3). The data are presented as the mean ± SEMBack to article page
