Usually diagnosed in children, teens and young adults, type 1 diabetes is an autoimmune disease in which the immune system attacks and destroys insulin-secreting beta-cells in the pancreas. As a result, people with type 1 diabetes can’t regulate their blood sugar levels and require insulin treatment for survival. Now, researchers have reversed new-onset type 1 diabetes in mice with pyramid-like DNA molecules called tetrahedral framework nucleic acids (tFNAs).
