• neurons exhibit alterations in stimulated removal of cell surface AMPARs
(J:145984)
• GluR1 and GluR2 removal from the cell surface after stimulation with N-methyl-D-aspartate (NMDA) is significantly slower with only 10% removed after 15 minutes of incumbation compared to 50% in wild-type
(J:145984)
• cultured neurons have defects in clathrin-mediated endocytosis (CME)
(J:146583)
• 60 minutes after induction of CME, mutant neurons have two-fold less uptake of tranferrin receptor from the cell surface than controls
(J:146583)

• treatment of hippocampal neuron cultures with NMDA does not produce a prolonged depression in mEPSC amplitude as it does in wild-type neurons
• using hippocampal CA1 slices, the 58 2% decrease in excitatory post synaptic current detected in WT slices after low frequency stimulation does not occur in mutant CA1 slices
