Autoimmune Disease
Autoimmune diseases arise from an inappropriate immune response of the body against substances and tissues normally present in the body. In other words, the immune system mistakes some part of the body as a pathogen and attacks its own cells. This may be restricted to certain organs (e.g. in autoimmune thyroiditis) or involve a particular tissue in different places (e.g. Goodpasture's disease which may affect the basement membrane in both the lung and the kidney). The treatment of autoimmune diseases is typically with immunosuppression—medication which decreases the immune response. (For a detailed explanation of pathogenesis see Autoimmunity.)

Famous quotes containing the word disease:
“I prithee, daughter, do not make me mad.
I will not trouble thee, my child; farewell:
We’ll no more meet, no more see one another.
But yet thou art my flesh, my blood, my daughter—
Or rather a disease that’s in my flesh,
Which I must needs call mine.”
—William Shakespeare (1564–1616)
