Role of CaMKII in Aβ regulation of surface GluR1 clusters.
A–C, immunocytochemical images of surface GluR1 staining in
cultured cortical pyramidal neurons (DIV 18) transfected (GFP+) with a
scrambled siRNA (A), CaMKII siRNA (B), or wild-type CaMKII
(C) without (control) or with Aβ (1 μm) exposure
for 3 days. D, cumulative data (mean ± S.E.) showing the
density of surface GluR1 clusters in control or Aβ-treated neurons
transfected with different constructs. *, p < 0.01,
ANOVA.
