This subset is hyporesponsive and anergic to antigen stimulation. Recently, it has been demonstrated to participate in the immune deficiency in human immunodeficiency virus infection and has close relationship with the development of acquired immunodeficiency syndrome. Meanwhile, the CD4(superscript +)D25(superscript +)Treg is also infected when the human body is invaded by HIV. The CD4(superscript +)CD25(superscript +)Treg will finally be killed by the mechanism of antibody-dependent cell-mediated cytotoxicity. Because of the decrease of the CD4(superscript +)CD25(superscript +)Treg, it can't function as a immune suppressor as a result of the excess of activation of HIV and gradually exhausting of the T cell, which shows that the CD4(superscript +)CD25(superscript +)Treg plays a inhibitory role in the different stages of the development of the HIV as well as different effects in the pathogenesis of AIDS.

It is well-known that for eucaryotic cells, DNA is located in the karyon and can not penetrate to the cytochylema and the tissue fluid because the cell membrane can act as barriers for DNA transportation. Therefore, the appearance of DNA in cell matrix and the serum can indicate that some diseases have taken place. A main reason for cancer occurrence is the mutation of DNA. It may cause the change of the sequence and expression of cancer suppressor genes.
