Looks like they are working on a 'vaccine' for autoimmune induced (ie type I) diabetes: http://www.businessweek.com/lifestyle/content/healthday/637852.html Already I see the potential for this to be the next medication that much of America will end up taking for life. If this tech works, it will most likely be extended to all kinds of autoimmune diseases like hypothyroid and arthritis. Might even work for poison ivy! But will it work as directed? Will it really be as precisely targeted as advertised? What kind of side effects should we expect from this nanotechnology? And as much as those suffering from autoimmune problems may need this right now, won't this direction also in many ways potentially distract us from targeting prevention or cure of the problem instead of just lifetime containment? But of course, big pharma does so love to develop medications that are required for the lifetime of the individual!
