sounds plausible.
i also heard something - which may be a fluke thing - about an aids infected man who received a bone marrow transplant from a person of normal health. he received the bone marrow transplant as treatment for some other condition.
according to the article, within a period of time he had exhibited no signs of Aids or HIV either through symptoms or blood testing... according to the article he was "cured"
ill have to find some more on it - it could have been total BS
EDIT:
here is the article
