FIGURE 2.
Aβ induces internalization of β2AR in HEK293 cells. A, effects of Aβ or isoproterenol on β2AR internalization are shown. Images show time-course effects of Aβ (10−6 m) and isoproterenol (Iso, 10−7 m) on β2AR internalization. B, levels of internalized β2AR after Aβ or isoproterenol treatment were quantified by biotinylation method. n = 8; *, p < 0.05; **, p < 0.01 versus control by two-way ANOVA followed by the modified Tukey test for multiple comparisons.
