Resveratrol impairs the production of amylin-bearing extracellular vesicles in INS1E-hIAPP pancreatic β cells. (A) Dynamic light scattering analysis of the exosomes purified from the different pancreatic β cells (n = 3). (B) Immunofluorescence staining using an antibody against amylin of the exosomes purified from INS1E-hIAPP exposed to either low or high glucose levels.
