Immune System Diseases

Our immune system is a highly complex and highly developed system with a simple mission to defend and help us fight off infection and kill invaders like bacteria and viruses that cause infection. If a person is born with a compromised immune system, death from infection by a virus, bacterium, fungus or parasite can occur.

Sometimes lack of an enzyme due to a genetic cause means that toxic substances can build up inside the cells of the immune system like In severe combined immunodeficiency (SCID).
