(Submitter supplied) After their destruction in adult mice, insulin-producing pancreatic beta-cells slowly regenerate from other islet cells, like glucagon-producing alpha-cells. However the molecular basis of this conversion is unknown. Moreover it remains unclear if this intra-islet cell conversion is relevant to human diseases with extensive beta-cell loss, like in type 1 diabetes (T1D). Here, we show that subsets of glucagon-expressing cells in subjects with T1D produce Insulin and other molecular features of beta-cells, accompanied by loss of the alpha-cell regulators DNA methyltransferase 1 (Dnmt1) and Aristaless-related homeobox (Arx). more...
