Why does the body's innate immunity fail in an aids patient?

It is an immunodefiency disease that causes immune cells, phagocytes (cells that eat bacteria and other bad stuff) to behave abnormally. Aids is such a disease. It cripples the immune system by interfering eith the activity of helper T cells, thus depressing cell-mediated immunity. Although the immune system tries to fight it off, over time a huge defecit in the development of antibodies to fight of the diseast and the T cells which are toxic to bad cells, is impared. The virus lives & multiplies in the lumph nodes giving no symptoms of the disease for up to 10 years until the lymph nodes can no longer hold all the virus which is when the immune system colapses and symptoms appear.
