GPER1 is involved in activity-dependent LTP at TA-CA1 synapses. A–D Plots of pooled data illustrating effects on synaptic transmission at juvenile TA-CA1 synapses. A Delivery of HFS (shown by arrow) resulted in the induction of LTP, however subsequent addition of G1 failed to alter synaptic transmission. B Application of G1 induced cLTP, but subsequent delivery of HFS failed to increase synaptic transmission further. Activity-dependent LTP and GPER1-induced LTP share analogous expression mechanisms. C In control slices, HFS readily induced LTP. D In interleaved slices exposed to the GPER1 antagonist, G15 (200 nM), delivery of HFS failed to induce LTP. GPER1 activation is involved in activity-dependent LTP
