Transplantation of pancreas or isolated Langerhans islets can cure type 1 diabetes. Xenografts from transgenic pigs represent a promising source to overcome the shortage of organ donors. We investigated the immunosuppressive effect of local LEA29Y expression (a high-affinity variant of CTLA4-Ig) by transplantation of neonatal porcine islet-like clusters (NPICCs) from INSLEA29Y transgenic pigs into humanized mice. NPICCs from 1–5 day-old pigs expressing LEA29Y und...

Primary aldosteronism caused by aldosterone-producing adenoma (APA) or bilateral adrenal hyperplasia is the most prevalent cause of secondary hypertension. Somatic mutations of KCNJ5, ATP1A1, CACNA1D and ATP2B3 have been shown to be involved in the formation of APA. We studied the immunoexpressions of CYP11B2 and HSD3B2, the rate-limiting enzyme for aldosterone production and the prevalent isoform of β-HSD found in APA respectively, and...
