| Summary |
Natural and stable cell identity switches, where terminally-differentiated cells convert into different cell-types when stressed, represent a widespread regenerative strategy in animals, yet they are poorly documented in mammals. In mice, some glucagon-producing pancreatic α-cells become insulin expressers upon ablation of insulin-secreting β-cells, promoting diabetes recovery. Whether human islets also display this plasticity for reconstituting β-like cells, especially in diabetic conditions, remains unknown. Here we show that two different islet non-β-cell types, α- and γ–cells, obtained from deceased non-diabetic or diabetic human donors can be lineage-traced and induced to produce insulin and secrete it in response to glucose. When transplanted into diabetic mice, converted human α-cells reverse diabetes and remain producing insulin even after 6 months. Insulin-producing α-cells maintain α-cell markers, as seen by deep transcriptomic and proteomic characterization, and display hypo-immunogenic features when exposed to T-cells derived from diabetic patients. These observations provide conceptual evidence and a molecular framework for a mechanistic understanding of in situ cell plasticity in islet cells, as well as in other organs, as a therapy for degenerative diseases by fostering the highly-regulated intrinsic cell regeneration.
