So my wife is a t1d for the last 36 years. The work we both believe in is a biological cure. I.e. identify the pathogen that triggers t1d developing a vaccine . As well as finding a cure for the people who are already sick. There is almost no incentive for any pharmaceutical company to pursue this , T1D drugs make them gobs of cash.
Is there much plausibility of such a cure? The problem is autoimmune AFAIK (maybe triggered by an infection), and once it happens the relevant cells are dead and it'd take both regrowing them and immunotherapy.
Whenever an article about T1D includes mention of an uncertain and unspecified future date, it’s relatively safe to replace it with “never.”
As someone with T1D, I won’t be holding my breath waiting for this. Personally I’m quite satisfied with multiple daily injections.
