Fig. 1From: Nrf2 activation through the PI3K/GSK-3 axis protects neuronal cells from Aβ-mediated oxidative and metabolic damageAβ42 oligomeric structures visualized by dot blot and electron microscopy. The presence of oligomeric forms of Aβ42 in the culture supernatants was assessed by dot blot analysis probed with anti-oligomer antibody A11 as well as by electron microscopy after negative staining. Left panel: freshly solubilized HFIP-treated Aβ42; right panel: conditioned media of cells challenged with Aβ42 for 24 h. Bar, 100 nmBack to article page
