Aβ1-42 monomers increased [Ca 2+ ] i in human monocytic THP-1 cells. (A) [Ca2+]i images obtained by Fluo-3 AM at 24 hours after treatment with either vehicle only (−) or 10 μM Aβ1-42 monomers (Aβ) in THP-1 cells. Scale bars represent 50 μm. (B) The histogram showing the ratio of [Ca2+]i levels to vehicle treated group. All data are presented as the means ± SEM (n = 3). **P <0.01, versus vehicle treated samples. Aβ, amyloid beta.
