Figure 6.
Role of Exo70 and Sec8 in the constitutive AMPAR trafficking at spines. (A) Similar to Figure 5B, surface analysis from pairs of spines and dendrites in GluR2 (first panel; n=21 spine/dendrite pairs from four different cells), GluR2 plus Exo70-N (second panel; n=32 spine/dendrite pairs from five different cells), GluR2 plus Sec8-Ct (third panel; n=58 spine/dendrite pairs from five different cells) or GluR2 plus NR2B-Ct cotransfected neurons (fourth panel; n=62 spine/dendrite pairs from five different cells). (B) Similar to Figure 5C, total receptor amount from the same pairs of spines and dendrites in GluR2 or in GluR2 plus Exo70-N, Sec8-Ct or NR2B-Ct cotransfected neurons. (C) Similar to Figure 5D, surface ratio of the same pairs of spines and dendrites in GluR2 or in GluR2 plus Exo70-N, Sec8-Ct or NR2B-Ct cotransfected neurons.
