A genetically modified cow has produced milk containing human insulin, according to a new study. The proof-of-concept achievement could be scaled up to, eventually, produce enough insulin to ensure availability and reduced cost for all diabetics requiring the life-maintaining drug.
Yeah type 1 is an immune response and type 2 is a lack of production.
So with 2 you could maybe up insulin production genetically. But that seems like a risky game haha
