6500, you are correct. I don't think that will have any effect on type I DM. As for type 2, most people can control it by diet and exersize it is just that most don't. It takes disipline and self-control.
However, the article states that substance P "cleared up" the islet cell inflammation that is typical in Type I DM and also curbed insulin resistance involved in both Types I and II, so there may be hope there also.
This is particularly interesting for me. I graduated with a BS in Biochemistry and focused on neuroscience; I spent 3 years working with rats and mice in neuropharmacological studies; and after graduating I worked for a major pharmaceutical company. Additionally, I'm a Type I diabetic of 14 years.
I'm having a difficult time being receptive to this as a major hope for Type I's, even though I badly want to believe it. The life-span of a rodent likely is too short to allow for the total demolition of their islet cells. Inflamation has been postulated as the course of the disease in the "honeymoon phase" where a Type I is not yet 100% insulin dependent but doesn't produce sufficient amounts of insulin. However, the honeymoon phase eventually ends in insulin dependence, which may not occur to the same extent in a species with a shorter life-span. And, even though in recent years there has been theories suggesting that some diabetics have a "chronic or extended honeymoon phase" that lasts decades, I still question how effective this will be.
The early studies of islet cell implants have all resulted in an immune response that kills the new islet cells. To my knowledge, these have been implanted in a silicone matrix inter-peritoneally, which has no high concentration of pain receptors. Since the islet cells still cause an immune response that leads to their failure, the implication is that anti-bodies and not pain receptors are the guilty culprit. Just my $0.02 based on the knowledge and experience I have.

yes that is what i found so interesting,,, also the conection between this and pain receptors and similarities in type 2 and md. i also am wondering about a delivery system for such a concept. oral or injectable? would this be similar to gene therapy? in any event any possible positive outcome will shurly piss off the major drug companies who are more interested in profits from treatment not curing. any way it was a glimmer of hope on the horizon to possibly save a life and reduce the amount of bullshit people must endure... now if they would just ban the major causes of diebetes, like oh say high fructose corn syrup which is in everything maybe we'd have half a chance. last part is just an opinion..
It seems like it'd have to be implanted or injected. Targeting pain recepters is possible, but not specifically the pancreas's. And if you targeted them all, it'd make for a very loopy life kind of like being on heroin all the time (opiate agonists target pain receptors).
Speaking of this, has there been a study on how opiate agonists affect bloodsugars in diabetics? Theoretically, by the line of reasoning in this article, extended use of them should cause an increase in insulin production if there's enough neuropeptide (which I'd assume there is).
It would be different from gene therapy. Gene therapy involves identifying diabetes before it manifests itself, and then either fixing the defective gene or fighting the defect. It mainly would help those that are pre-disposed to diabetes but don't yet have it. This new possibility is a way to treat those that already have it.
And while I don't whole-heartedly agree with banning high-fructose corn syrup, I do agree that people should be wary of their health. There's no doubt that life-style choices might play a part, but it's not the cause of diabetes. Many diabetics are diagnosed in infancy before they ever had high-fructose corn syrup, and plenty of Type IIs are in perfect health besides having an unlucky gene.
I'll check into this some more over Xmas and post any findings.
