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. Adoptive immunity
Immunity to disease or infection conferred on a previously non-immune individual by transferring lymphocytes from a previously immune individual to the non-immune individual.

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. B cells
Type of lymphocyte responsible for antibody-mediated immunity ; mature in the bone marrow and circulate in the circulatory and lymph systems where they transform into antibody-producing plasma cells when exposed to antigens .

5. B lymphocyte (B cell)
A cell produced by the bone marrow which, when stimulated by an antigen , becomes either a memory cell or a plasma cell that forms antibodies against that antigen. Compare T lymphocyte .

6. Burkitt's lymphoma (B cell lymphoma)
A type of cancer associated with the Epstein-Barr virus (EBV), though it is not known if EBV actually causes the tumor or not. This lymphoma of the B lymphocytes is rare in developed countries but is relatively common among people living in New Guinea and East Africa.

7. Bursa of Fabricius
A saclike organ found in the cloaca (excretory and reproductive opening) of birds which produces B lymphocyte s.

8. Cerebrospinal fluid (CSF)
Cerebrospinal fluid is the clear fluid that fills the cerebral ventricles and subarachnoid space (the areas that surround the brain and the spinal cord). It is produced by the choroid plexuses. Normal values: * opening pressure: less than 180 mm H2O * appearance: clear * cells/uL: lymphocytes: 0 -5; Polymorphs: 1 - 3; RBC:20 - 50 * glucose: 45 - 85 mg/dL * protein: 15 -45 mg/dL

9. Clonal selection
A theory that each B or T lymphocyte , when stimulated by antigen , divides to form a clone of itself.

10. Concanavalin A (con A)
A protein found in the jack beans plant Canavalin ensiformis which sticks various cell types and glycoprotein s (proteins with sugar s attached) to one another by crosslinking them. It can also function much like platelet s in blood do for animals. Also, it encourages mitosis and cell division in dormant lymphocyte s. It is used in the lab technique of affinity chromatography to purify glycoproteins.
