IL-17 is expressed on beta and alpha cells of donors with type 1 and type 2 diabetes.

ABSTRACT:

Purpose

IL-17 is an important effector cytokine driving immune-mediated destruction in autoimmune diseases such as psoriasis. Blockade of the IL-17 pathway after the initiation of insulitis was effective in delaying or preventing the onset of type 1 diabetes (T1D) in rodent models. Expression of IL-17 transcripts in islets from a donor with recent-onset T1D has been reported, however, studies regarding IL-17 protein expression are lacking. We aimed to study whether IL-17 is being expressed in the islets of diabetic donors.

Methods

We stained human pancreatic tissues from non-diabetic (n = 5), auto-antibody positive (aab+) (n = 5), T1D (n = 6) and T2D (n = 5) donors for IL-17, Insulin, and Glucagon, and for CD45 in selected cases. High resolution images were acquired with Zei
