Effect of amyloid beta (Aβ) 1–40 exposure on the cells of a human adult retinal pigment epithelial cell (ARPE-19) line in culture. The ARPE-19 cells were incubated for 48 h with different concentrations of Aβ 1–40, and the number of living cells were determined by the WST-8 assay. The number of living cells was increased by exposure to 5 μM Aβ 1–40 but the number of living cells was decreased by 25 μM of Aβ 1–40 compared to the control group. Data are the means ± standard error of the means (SEMs) for each group (n = 4)
