France studies the group announces 10 days jointly, they discovered " the person that AIDS virus is restrained " a kind of T in the body the inhibition of lymphocyte mechanism, reach the main distinction of this kind of lymphocyte in its and other crowd body. This discovery will conduce to the research of AIDS vaccine.

Be in early 2005, france compares hospital of Er of spy of a place of strategic importance to discover, the person that the AIDS virus that is less than １ ％ about is affected is in after affecting more than 10 years, although did not pass any cure, but the AIDS virus amount in its blood did not change basically, and become AIDS patient without development. This discovery causes the attention of institute of French country AIDS, organize France the hospital combines health of nation of Pausteur institute, France and medical research center and Bisaiteer to be called to these " the person that AIDS virus is restrained " the person undertakes study, with period open among them mystery.

Their research target is 11 " the person that AIDS virus is restrained " , infection history is in their AIDS virus 10 years above, some people are in even 20 years of above. Researcher discovers above all, the T-CD4 lymphocyte of these patients (the attack cell of AIDS virus) the reaction to AIDS virus and other crowd as good as, this makes clear them and can not avoid to affect the special ability of AIDS virus, they contracted AIDS virus really.

Subsequently, researcher diverts attention to T-CD8 lymphocyte again (cellular toxin T lymphocyte) on. Researcher discovery, the person that affect with other AIDS virus or patient are different, "The person that AIDS virus is restrained " this kind of lymphocyte in the body was not destroyed by AIDS virus. Researcher puts the T-CD4 lymphocyte in these patient bodies and T-CD8 lymphocyte test tube to undertake study to discover at the same time, the T-CD4 lymphocyte that contracted AIDS virus is eliminated by a large number of rapid ground, and the trace that among them AIDS virus also does not have any continueing that breed. On this foundation, researcher returns discovery, "The person that AIDS virus is restrained " the T-CD8 lymphocyte structure in the body and other crowd differ somewhat.

Researcher expresses, this discovery is major, be expected to pass imitate " the person that AIDS virus is restrained " the special function of T-CD8 lymphocyte, development goes new generation vaccine, raise AIDS to treat a level.
