Most recently, a completely new subset of NK cells with immunosuppressive functions has been identified. These cells are able to downregulate conventional NK cells in a PD1-ligand dependent manner and are, therefore, responsible for tumor outgrowth.The aim of our present study was to investigate the role of this new NK subset in autoimmunity. For this purpose, we used two independent mouse models. In the NOD mice, we found a large increase of suppressive...

The mechanisms that lead to tumor formation of and aldosterone secretion by zona glomerulosa cells in primary aldosteronism are not known. Recently, endothelial cell-derived factors have been characterized that control the release of aldosterone by adrenocortical cells. In addition, we started to characterize the regulation of CITED2, a CBP/p300 interacting transactivator with ED-rich tail 2. Earlier, it was shown in mice that absence of CITED2 leads to adrenal agenesis. Since...
