Look at it this way. If it don't bring a cure they are hoping for it could do away with injections, something many people will be happy with.
I know it doesn't say if the mice where type 1 or 2, but to me it looks like they were type 1. I imgine the drug could be used to treat type 1 and type 2. I look at this way when it comes to research. If they come up with a treatment for type 1 it could trickle through to help type 2's and if they come up with a treatment for type 2 it might help type 1,s as well. I know type 1 and type 2 are different and why. This next link looks at a treatment for type 1 but it could be used for type 2 as well.
And with treatment below there is no need for anti rejection drugs.
