Amylin, α-synuclein, tau and PrP immunoreactivity in endocrine pancreatic cells. Immunohistochemistry for amylin (a–d), α-synuclein (e–h), Tau (i–l), and PrP (m–p) in pancreatic cells from subjects with a normal neuropathological examination and no history of T2DM (a, c, i, m), with a normal neuropathological examination and history of T2DM (b, f, j, n), with Parkinson`s disease (PD), dementia with Lewy bodies (DLB) or incidental Lewy body disease (ILBD) (c, g, k, o) or with Alzheimer’s disease (AD) (d, h, l, p): 40 × magnification; scale bar = 50 µm. Violin plots showing amylin (q), α-synuclein (r), Tau (s) and PrPc (t) immunoreactivity quantification in endocrine pancreatic cells: **: p ≤ 0.05, ***: p ≤ 0.001; ****: p ≤ 0.0001
