(A, B) Hippocampal LTP induced by weak HFS (A) or regular HFS (B) in the CA1 region of hippocampal slices from LV-miR132 injected SH mice (red circles, n=7 slices/from 5 mice) vs. LV-control injected SH mice (black diamonds, n=7/4). (C) miR132 overexpression (red diamonds, n=7/4) prevents the ability of soluble Aβ oligomers (7PA2 CM) to impair HFS-induced LTP, whereas the LV-control vector does not (black diamonds, n=6/4). (D) The same as in (C) but using pure, aggregated synthetic Aβ1-42 (LV-control: black circles, n=7/4; LV-mi132: red diamonds, n=7/5). Inset traces are typical fEPSPs recorded before (gray) and after (black, red) HFS for each condition. Horizontal calibration bars: 10 ms; vertical bars: 0.5 mV.
