Figure 7. Expression of ERα in ER-αKO hippocampal slices restores synaptic responses to β-estradiol 3-benzoate (EB).
EF1α-ERα lentivirus was injected unilaterally into the hippocampus and EF1α-GFP lentivirus was injected into the contralateral hippocampus of (a) female and (b) male ER-α knockout (ER-αKO) mice. Expression of estrogen receptor-α (ER-α) (filled circles) was associated with enhanced EB responsiveness relative to slices expressing green fluorescent protein (GFP) (open circles).
