From a purely biological perspective, curing diabetes is a puzzle of cellular engineering and immune evasion. For Type 1, the scientific community is highly focused on stem cells and gene editing. If we can use CRISPR to modify stem-cell-derived beta cells so they are invisible to the immune system, we solve both the donor shortage and the need for immune-suppressing drugs. For Type 2, the science points toward metabolic rewiring, exploring how gut hormones (like GLP-1) can be harnessed to reset the body's weight and insulin sensitivity set-points.
