Fig. 3From: iPSC-derived familial Alzheimer’s PSEN2 N141I cholinergic neurons exhibit mutation-dependent molecular pathology corrected by insulin signalingChronic insulin administration reduces the Aβ42/40 ratio in the conditioned media of BFCNs harboring FAD mutations. ELISA quantification of iPSC derived basal cholinergic neurons measuring amyloid β. Cells (DIV 34) were insulin deprived for 3 days or given 1000 ng/mL every 24 h for 3 days. Aβ 40 (a), Aβ 42 (b), and Aβ 42/40 (c) measured in collected media. These data correspond to results of 2 independent experiments. * P < 0.05; ** P < .01Back to article page
