What is an improvement depending on the antibody?
When a potentially harmful substance, such as a virus or bacteria, enters the body, cells in the immune system produce antibodies. Antibodies are proteins that have been established to specific harmful attackers or antigens, neutralize and prevent infection. The next time the body enters the body, the immune system remembers it and the antibodies are produced much faster to deal with it. In the case of some diseases that are repeated, such as dengue fever, antibodies connect to the dengue virus, but cannot neutralize it. Instead, they actually make the virus more capable of entering cells and infecting them, and this is called an improvement in the antibody.
Antibody enhancements can worsen the disease because it allows viruses to connect to cells and cause infection. In addition to its connection with the dengue fever, it is also assumed that it occurs in HIV infection and influenza -dependent antibodies. Although none of these diseases can be cured, many people from feverDengue and flu without treatment and drugs can prolong the life for those with HIV.
In the case of dengue fever, there are several different forms of the virus. Normally, during the first infection with dengue, patients do not experience any symptoms or only minor symptoms. When again, with another form of dengue, there are more serious symptoms. They may include high fever, skin rashes, headaches and vomiting. This is the conversion of what is usually done with immunity when the second episode of infection is recognized and solves much faster and more efficiently.
Improvement of antibody depends because antibodies are produced that connect to one part of the dengue virus. This part is the same in all different forms of the virus, so the antibodies can connect to everyone. Other, different parts of the virus are responsible for infection, so antibodies are unable to neutralize all different forms. When a new form of dengue virus enters the body, an antibody joins him, but the virus remains intact.
When an antibody is attached to the virus, the body does not connect any other immune response and the virus is unmoted. This is sometimes referred to as the original antigenic sin because the body retains its first response to the antigen as if it were indelibly marked. In addition to allowing the virus to remain under the radar of the immune system, it allows it to enhance the dependent antibody into the cells and infect them. This is because the antibody attached to the virus can bind to cellular receptors. The virus can then enter cells that he could not connect himself.
