1. Adjuvant
* In pharmacology, a substance that, when added to a medicine, speeds or improves its action. * In immunology, a substance that is added to a vaccine to improve the immune response so that less vaccine is needed to produce more antibodies. Such adjuvants apparently work by speeding the division of lymphocytes and by keeping the antigen in the area where the immune response is taking place. In research with humans, aluminum phosphate and aluminum hydroxide gel are commonly used; in research involving lab animals, Freund's adjuvant is used.

2. Anaphylactic shock (anaphylaxis, type I reaction)
A potentially fatal form of shock brought on by an extreme allergic reaction or immune response; symptoms include a sudden drop in blood pressure, difficulty in breathing, reduced body temperature, and nausea.

3. Antigen processing / presenting cell
A type of cell which provokes an immune response from T lymphocyte s by binding foreign antigen s to their surfaces and then interacting with the T cells.

4. Biological response modifier
One of a group of protein s which modify the immune response of an organism.

5. Cell-mediated immunity
A type of immune response mediated by killer T cells which the body uses to destroy cells with foreign antigen s (like tumor cells, cells that have become infected with a virus , organs or tissues donated by a non-matching individual, etc.)

6. Hapten
A small molecule which is not by itself an immunogen (can cause an immune response ), but has at least one element of an antigen and can combine with an antibody or another larger carrier molecule to become immunogenic.

7. Hyperergia
A condition where the body has a much larger immune response to a given antigen than normal, including hypersensitive allergic reactions.

8. Immune reaction
The reaction of the immune system to the presence of an antigen , which includes making antibodies and developing immunity to the antigen on a cellular level. Compare with immune response .

9. Immune response
The reaction of the body as a whole (not just the immune system , as in an immune reaction ) to the presence of an antigen , which includes making antibodies, developing immunity , developing hypersensitivity to the antigen, and developing tolerance .

10. Immune-response gene
Any of several gene s of the major histocompatibility complex that control the immune response of lymphocyte s to specific antigen s.
