For a long time, the medical community found in clinical treatment that all those who received intensive treatment

The method for detecting viral antigens and antibodies in body fluids of HIV-infected persons is convenient to operate and easy to popularize, and antibody detection is particularly common. But HIv P24 antigen and virus

The common method is the co-culture method, that is, mononuclear cells are separated from normal human peripheral blood, stimulated and cultured with PHA, and then added to the diagnosis of mononuclear cells and AIDS research in patients.

Lymphocytes in the patient's own periphery or bone marrow were stimulated with PHA for 48 to 72 hours for in vitro culture (IL2 was added to the culture medium) 1 to 2

HIV not only makes it difficult for the body's immune system to resist its aggression, but also gives special treatment drugs and preventive

In September 2009, a U.S. military-supported medical trial in Thailand found that an experimental vaccine could

Reported on March 6, 2019, a man living with HIV in the British capital London received a bone marrow transplant three years ago and "inherited" the genetic mutation of the donor.
