I am sure I read about an American trial of a closed loop system with a CGM and pump with both insulin and glucagon which gave good results. I will try and find linkAnd frankly, the algorithms that we see in the "Artificial Pancreas" arena really don't use the best Quantitative approaches. Interstitial glucose levels move with a reasonably consistent time lag to core blood levels. A good quant algo linking CGM and a pump can sugar surf without the diabetic having to think about it. It would take a day to become acclimatized, but on a five minute basis would be fully capable of driving a pancreas replacement. And if the pump had glucagon as well in a small footprint, then it could manage the blood levels very effectively.
Feeling miserable about it and wish there was a cure? Get over it - you're wasting your brain power and your life.
We don't have any islets, and they don't regrow. The only way to get them back is to reintroduce them - transplant them - so until they can grow islets which don't get killed by your immune system as a foreign body ('rejection'), the only option is to grow them for individuals, which is a MASSIVE and prohibitively expensive undertaking.
You are taking a very pessimistic view of the world @BigRedSwitch . You are also missing a big chunk of what is within the art of the possible with gene therapy and genetic manipulation. It is possible to flick a genetic switch to cause a set of cells to do something different. The trick is to know what to flick, and that's something we just don't know now. It does not require an external donor source, and you won't need to regrow anything. This approach is being looked at for a number of chronic conditions.
If you look into it, you'll find that a couple of inherited disorders, Beta Thalassemia and Choroideremia have successfully undergone gene therapy trials to treat them. Choroideremia is the most applicable to Diabetes as it is a condition where the degeneration of several layers of cells that are essential to sight occurs, causing blindness. The gene therapy treatment caused improvements to sight.
This stuff isn't science fiction. It is deeply researched and although at an early stage, there is no reason why a gene therapy treatment for Diabetes, allowing cells to produce insulin once more within the body, isn't possible.
I don't pretend that I will see this happening in my lifetime. I think the vaccine for prevention might get here in that time, but I think the gene therapy will take longer. But as I said earlier, a cure is very much within the realms of biotechnology and has no dependency on transplants or external growth of our own cells and replantation. As someone else said, we will be remembered as those who suffered a condition that was wiped out.
I think we need to agree to disagree. There has been a reasonably large amount of research into Gene Therapy for diabetes. Both diabetic mice and rats have seen temporary "cures" via this method and a company called Insulete was seeking permission for human trials of this technique 2 years ago. It appears that the need is for the "Vaccine" to stop the insulin producing cells from being attached once this therapy has been applied.The problem is, in both the conditions you mention, there are still cells that remain. That's not the case in type 1 diabetes
Note that as well as finding c pep in the majority of living T1s in this study they also found histological evidence of at least a few insulin positive cells in nine pancreases examined post mortem. (some had very few but a couple far more so it does seem to be variable)n summary, the study of a large group of insulin-dependent diabetic patients of extreme duration characterized clinically, biochemically, and histologically has provided the surprising finding that residual functional β-cells remain even after 50 years in a majority of these type 1 diabetic patients. The data presented in this study clearly support that even under prolonged autoimmune and metabolic stress, pancreatic β-cells can be replenished
