Regulation of stress-enabled hippocampal LTD. (A) Reliable LFS-induced, stress-enabled LTD was found in WT slices, but not p75NTR-/- slices (P<2×10-6). (B) LTD induced by NMDA (7min, 10μM) was similar between WT and p75NTR-/- mice (P>0.05). (C) LTD induced by carbachol (10min, 50μM) was similar between WT and p75NTR-/-(P>0.05). (D) Reliable stress-enabled LTD was induced in slices from scrambled peptide-injected, but not GluA23Y peptide(P<5×10-5). (E) Reliable stress-enabled LTD was induced in slices from saline injected mice, but not scopolamine injected mice (P<0.003). (F) NMDA-induced LTD was normal in slices from scopolamine injected mice. Note saline group is shared with control group in Fig. 1B.
