Visualization of Amylin Protofilaments (IMAGE) University of Leeds Caption The image shows the structure of the amyloid fibrils in the wild-type amylin and also in the S20G variant. On the left of the image, fibrils from wild-type amylin are made up from layers containing two molecules that are stacked side by side. In the S20G variant, there is a third molecule per layer. This structural arrangement could lead to a greater propensity for aggregation.
