Scientists have reported a major breakthrough that could change future treatment for Diabetes. The research shows that type 1 Diabetes may be prevented and even reversed in mice.
The study used a combination of donor stem cells and insulin-producing islet cells. Researchers say this approach helped reset the immune system in the treated mice.
Type 1 Diabetes happens when the immune system mistakenly attacks insulin-producing beta cells. These cells are found in the pancreas and are essential for controlling blood sugar.
In the new experiment, scientists created a mixed immune system. This system is called chimeric because it includes both donor and recipient immune cells.
This change allowed the body to accept new islet cells. It also stopped the immune system from attacking the pancreas again.
Before the transplant, mice received low-dose radiation. They were also given specific antibodies to reduce immune activity in a controlled way.
After that, researchers transplanted donor blood-forming stem cells. These helped rebuild a more tolerant immune system in the body.
Healthy donor islet cells were also added. These cells restored insulin production and improved blood sugar control.
A short course of immunosuppressive drugs was used as part of the treatment. This helped the body accept the transplanted cells more effectively.
The results were very strong. In the study, transplanted cells were not rejected by the immune system.
Researchers also reported no graft-versus-host disease in the mice. This is a serious condition that can happen after transplants.
Most importantly, Diabetes was either fully prevented or completely reversed in the test groups.
In one group, all 19 mice remained free of Diabetes. In another group, all 9 mice already affected were fully cured.
Scientists noted that many parts of the treatment are already approved for human use. This includes drugs, antibodies, and radiation techniques.
This increases the possibility of future human trials. However, researchers say some challenges still remain.
One major issue is the limited supply of human islet cells. Another challenge is finding compatible donor matches.
Researchers are now exploring lab-grown islet cells. They are also working on producing larger amounts of usable tissue.

If successful in humans, this approach could offer a potential cure for Diabetes. It may also help treat other autoimmune diseases in the future.
