Lymphocyte-Derived Exosomal MicroRNAs Promote Pancreatic β Cell Death and May Contribute to Type 1 Diabetes Development

？ T lymphocytes release exosomes containing specific microRNAs ？ T lymphocyte exosomes can transfer microRNAs to rodent and human pancreatic β cells ？ The transferred microRNAs trigger chemokine expression and apoptosis of β cells ？ Blockade of microRNAs transferred in β cells decreases diabetes incidence in NOD mic
