- # 60 Action Of B-lymphocytes
A B-lymphocyte places some of its specific receptor molecules in its cell surface membrane. If it encounters an antigen that binds with this receptor, the B-lymphocyte is activated. It divides repeatedly by mitosis to produce a clone of genetically identical plasma...
- #59 The Immune Response - Lymphocytes
Lymphocytes, unlike phagocytes, act against specific pathogens. Each lymphocyte contains a set of genes that codes for the production of a particular type of receptor. We have many million different types, each producing just one type of receptor....

| Niels Kaj Jerne (1911-1994) |
Coined: in 1960 by Danish immunologist Niels Kaj Jerne (1911?1994) who proposed that an antigen particle carries several epitopes.
Definition:
The surface portion of an antigen which is recognised by immune system (antibodies, B or T cells) and elicit an immune response. The part of an antibody that recognizes the epitope is called a paratope.
