Clinicopathologic characteristics of pancreatic islet amyloidosis in the rhesus macaque (Macaca mulatta) and sooty mangabey (Cercocebus atys).

Histopathology results showed that the defined amyloid characteristics are associated with clinical diabetes in both species. The immunohistochemistry results collectively suggest differences in pancreatic hormones and islet amyloid components among both species and diabetic status.
