Scientists cured type 1 diabetes in mice by creating a blended immune system

Scientists have cured type 1 diabetes in mice, without long-term immune suppression.

In type 1 diabetes, the immune system attacks insulin-producing cells, and replacing them with transplanted cells from donors has historically required people to take strong immunosuppressants for life, which severely limited the reach of such transplants.
