Blood type? Oh ... positive?

An Australian girl has taken on her liver donor's immune system following a transplant.

"We were stunned, absolutely stunned, and also very puzzled,'' said Dr Stormon, who reported the novel case in the New England Journal of Medicine.

I'm amazed this isn't front page news on every paper today as surely it opens up a whole new world of possibilities.

Quite aside from the fact that if we can work out how it happened there need never be another case of tissue rejection following an organ transplant again, we surely have the possibility to help people with all manner of auto-immune diseases?
