Antibody A disease-fighting protein created by the immune system in response to the presence of a specific antigen.
Antifungal An agent that destroys or inhibits the growth of fungi.
Antigen Any substance that the body regards as being foreign.
antigen-antibody reaction Involves the binding of antigens to antibodies; also known as the immune reaction.
autoimmune disorder any of a large group of diseases characterized by a condition in which the immune system produces antibodies to work against its own tissues.

Bacteria One-celled microscopic organisms.
Candidiasis An infection that occurs on the skin or mucous membranes in warm, moist areas such as the vagina or mouth and are caused by pathogenic yeast; also known as a yeast infection or thrush.
Carcinoma A malignant tumor that occurs in epithelial tissue.
carcinoma in situ A malignant tumor in its original position that has not yet disturbed or invaded the surrounding tissues.
complement system A group of proteins that normally circulate in the blood in an inactive form.
Cytokines A group of proteins such as interferons and interleukins released primarily by the T cells that act as intracellular signals to begin the immune response.
