Theory of antibody formation

WebbThe development of the present theories of antibody formation serves as an outstanding example of the rapid progress of scientific knowledge and its interpretation; accordingly, an historical review may help to clarify current ideas. Like many other subdivisions of biology, immunology is in the midst of a period of great productivity and rapid accumulation of … Webb18 maj 2024 · Two views concerning the mechanism of antibody formation are at present most widely favored. One is the “antigen-template” theory, developed by Breinl, Haurowitz, Mudd, Alexander, and Pauling. This theory assumes that antibodies can be produced only by cells in which the antigen is present.

WebbThe theory states that in a pre-existing group of lymphocytes (specifically B cells), a specific antigen activates (i.e. selects) only its counter-specific cell, which then induces that particular cell to multiply, producing identical clones for antibody production.
