The mAbs engage hIAPP protofibrils in human T2D. Immunofluorescence shows increased hIAPP protofibril staining in pancreatic islet tissue from a T2D donor compared to nondiabetic control with a) 07G10 and b) 10H04. c) Magnified inset shows co‐localization of protofibril signal and hIAPP aggregate signal detected by ThS staining with protofibril signal localized at the core of larger aggregates. mAb (magenta), ThS (yellow), nuclei (cyan). Co‐localization of protofibril signal and ThS signal is indicated by white arrowheads.
