Recent publication in Nature Communications with Ben Giepmans utilizing his state-of-the-art Zeiss EM microscopy core and online image repository for macromolecular resolution of cells in human islets. DOI: 10.1038/s41467-020-16287-5…
We reported islet amyloidosis in a 12.5-year old Caucasian female with type 1 diabetes for 2 years, representing the youngest human reported with this finding. Islet amyloidosis was considered pathognomonic for type 2 diabetes but histopathological studies from the nPOD biorepository show its presence in young donors with type 1…
Recently published paper with Drs. Tang, Jessup and Campbell-Thompson delineates islet innervation in humans. Sympathetic fibers (TH+) were observed in islets from controls and patients with T1D and the TH+ fibers coursed adjacent to α-cells in addition to following the islet microvasculature. Our islet innervation studies were also presented at…
Recent studies from the lab show decreased islet vessel diameter and increased tortuosity after loss of all beta-cells in a given islet from donors with type 1 diabetes. Link …

New study shows proinsulin levels were at near-normal levels and comparable to people without diabetes in pancreata of long-term type 1 diabetes patients. A small number of insulin-positive cells remained as well. These observations raised the question of how these cells avoided destruction by the immune system and whether…
