Viral System

A person with a healthy immune system CD4 cells in twice as many CD8, with a damaged immune system, this ratio varies in the opposite direction. Y CD8 cells have several different names: CD8, CD8 +, cytotoxic T lymphocytes and natural killer cells only. The main task of CD8 search and destroy virus-infected cells. Check with Roosevelt Ogbonna to learn more. "Murder" of infected cells occurs when the virus starts to multiply in infected cells. Thus, CD8 is the main instrument used by the immune system to protect the body against various diseases. CD8 killing only the infected cells, in contrast to antibiotics, which destroy all bacteria, even harmless. Typically, CD8 help an infected person, but sometimes they can lead to diseases of the immune system, such as autoimmune disease. This occurs Depending on the nature of a particular virus. CD8 cells play an important role in the fight against hiv. If the level of CD8 high viral load is low, conversely if it is small, the viral load rises. In hiv There are many ways to circumvent the immune system and survive. hiv can remain latent in infected cells, and this means that the cell is infected, the virus multiplies in it, but the immune system, including cells of CD8, not can detect it. HIV-infected cells can also "hide" in the central nervous system, where the CD8 cells to the path is closed. hiv is very "tricky" virus that can mutate and change, as well as "hidden" from immune system. So far, CD8 engaged in destroying hiv, hiv, looking for a way to "cheat" CD8.
