Blood type changing spontaneously with a transplant?
I read recently that an Australian teenager, Demi-Lee Brennan is the first known transplant patient to change blood groups with the transplant. Apparently she was originally an o-negative and changed to an o-positive following a liver transplant, after her body performed its own bone marrow transplant and adopted the donor's immune system. Because of this the girl will not have to tae anti-rejection drugs for the duration of her life...
So my questions are:
How is this possible?
Is it possible for a patient with this outcome, to have its body reject its own blood and organs in favour of a donor's?
What does liver damage do to the homeostatic mechanisms in the body?
What impacts would or should this case have on future science?
And how do the immune response systems assist us in survival and homeostasis?
