Figure 2. Effects of Aβ-m, Aβ-o, and Aβ-f on SH-SY5Y cell membrane fluidity in the presence and absence of GQDs.

(A) GP shifts (represented by letter d) were recorded after a 3 h-treatment by Aβ-m, Aβ-o and Aβ-f (20 μM) of Aβ42. Compared with Aβ-m and Aβ-f, Aβ-o caused a large positive GP shift. GQDs prevented perturbation to membrane fluidity induced by Aβ-o and restored the GP values to that for control cells, especially at 10 and 50 μg/mL.
