Chronic AChE increases the synaptic expression of GluR2

Note. Postnatal hippocampal neurones from 1, 3, and 5 DIV were treated with 0.01 and 0.05 U/ml AChE every day for 5 days. The number of clusters of the presynaptic marker SV2a, for GluR2 and the extent of colocalisation (puncta immunostained with both antibodies), are shown per 100 μm of dendrite.
