Describe systemic autoimmune disorders
What will be an ideal response?
In systemic autoimmune disorders, the body's immune system mistakenly attacks its own cells and tissues. The immune system is dysregulated in that it fails to recognize self from other. Immune dysregulation is an under- or over-reaction of the immune system to exogenous or endogenous threats. In autoimmune disorders, the immune dysregulation is an example of an over-reaction against mistaken endogenous threats. Over-reactions of the immune system are believed to play a role in transplant tissue rejection and in well known autoimmune diseases such as lupus erythematosus and rheumatoid arthritis.
