摘要
The pathogenesis of type II diabetes can be linked to cosecreted hIAPP/insulin interacting with cell membranes. Here we investigate the nanostructures by co-assembling hIAPP and insulin on surfaces. By tuning the hIAPP/insulin ratio, atomic force microscopy reveals the resulting nanostructure morphology changes from fibrils to oligomers, to annular. Implications for in vivo studies are discussed.
