Heterogeneity in distribution of amyloid-positive islets in type-2 diabetic patients.

Amyloid-containing (A+) islets are characteristic for type-2 diabetes (T2D), but their abundance seems variable among patients. It is unclear whether the distribution of A+ islets follows a certain pattern or occurs randomly throughout the pancreatic organ. We investigated the topography of A+ islets in eight pancreata of T2D patients and eight sex- and age-matched non-diabetic subjects.
