I have had type 1 diabetes for 25 years and have used an insulin pump since 1994. I also work in the diabetes industry.
I am sorry to say that I feel that a "cure" is not on the horizon at this point. Some hopeful areas of study include genetic marker testing to identify a predisposition for type 1, smart cells glucose dependent insulin where insulin becomes active only after glucose elevation, everyone has been working on a vaccine to prevent the overaggressive autoimmune response that causes T1. I just feel that we are not very close to a biological cure. I feel something approaching a technological cure (closed loop smart insulin pump) will likely be first.
Exubera was just foolish. Why would a physician risk potential lung damage to a patient? Conventional insulin has been used for 85 years and is proven safe. Yes there is a poke but people need to get used to it. They are (or should be) poking their fingers with a lancet anyway in order to test blood. Patients need to get over needle-phobia, when they do they'll find their health is much better because of it.
