According to Xinhua News Agency, some people in London have a natural ability to fight AIDS, although they are infected, they never get sick. A new study suggests that this may be because an immune cell in their body has a unique "trained" experience. This discovery will help to develop new drugs for the treatment of AIDS.
The British "Nature" magazine website reported on the 5th that researchers from institutions such as the Massachusetts Institute of Technology in the United States have discovered the uniqueness of immune cell T cells in natural anti-AIDS patients. T cells are responsible for attacking pathogens such as viruses and bacteria in the immune system, but they must first be "trained" in the thymus to learn to recognize the normal proteins of the human body to avoid wrong attacks. They can only enter the immune system after qualified "graduation".
The researchers believe that due to genetic mutations, natural AIDS-resistant people have fewer types of normal proteins used to "train" T cells in the thymus, so T cells are very active and attack many unrecognized proteins. Even if the HIV is mutated Being attacked, the virus is suppressed and it is not easy to cause AIDS. One basis for proposing this theory is that people with similar genetic mutations often suffer from immune system diseases because T cells are too active and normal proteins in the body are attacked.
