Fifty Years of Pancreatic Islet Pathology in Human Type 1 Diabetes: Insights Gained and Progress Made
Diabetologia (2018) 61:2499–2506 https://doi.org/10.1007/s00125-018-4731-y REVIEW Fifty years of pancreatic islet pathology in human type 1 diabetes: insights gained and progress made Noel G. Morgan1 & Sarah J. Richardson1 Received: 18 June 2018 /Accepted: 13 August 2018 /Published online: 25 September 2018 # The Author(s) 2018 Abstract Type 1 diabetes is increasing in incidence in many parts of the world and it might be imagined that the pathological processes that underlie disease progression are firmly understood. However, this is not the case; rather, our collective understanding is still surprisingly rudimentary. There are various reasons for this but one of the most important is that the target organ (the pancreas) has been examined at, or soon after, diagnosis in only a small number of cases worldwide over the past half a century. This review provides a summary of some of the insights gained from these studies and highlights areas of ongoing uncertainty. In particular, it considers the process of insulitis (a form of islet inflammation that occurs characteristically in type 1 diabetes) and discusses the factors that may influence the access of immune cells to the beta cells. Attention is also drawn to recent evidence implying that two distinct profiles of insulitis exist, which occur differentially in people who develop type 1 diabetes at increasing ages. Emphasis is also placed on the emerging (and somewhat surprising) consensus that the extent of beta cell loss is variable among people with type 1 diabetes and that many (especially those who are older at onset) retain significant numbers of insulin-producing cells long after diagnosis. -
