In immunology, clonal selection theory explains the functions of cells of the immune system (lymphocytes) in response to specific antigens invading the body. The concept was introduced by Australian doctor Frank Macfarlane Burnet in 1957, in an attempt to explain the great diversity of antibodies formed during initiation of the immune response .
The clonal selection theory became one of the central concepts of immunology, and Burnet regarded his contributions to the theoretical understanding of the immune system as his greatest contribution to science, [108] writing that he and Jerne should have received the Nobel for this work. [109]
In the late 1950s however, the works of three scientists—Jerne, Talmage and Burnet (who largely modified the theory)—gave rise to the clonal selection theory, which proved all the elements of Ehrlich's hypothesis except that the specific receptors that could neutralize the agent were soluble and not membrane-bound.

Clonal Selection Pseudo code on AISWeb; CLONALG in Matlab developed by Leandro de Castro and Fernando Von Zuben; Optimization Algorithm Toolkit in Java developed by Jason Brownlee which includes the following clonal selection algorithms: Adaptive Clonal Selection (ACS), Optimization Immune Algorithm (opt-IMMALG), Optimization Immune Algorithm (opt-IA), Clonal Selection Algorithm (CLONALG ...
When Sen. Tom Cotton (R-Ark) raised the theory, he was chastised for “repeat[ing] a fringe theory suggesting that the ongoing spread of a coronavirus is connected to research in the disease ...
The theory accounts for the ability of T cells to have regulatory roles in both helping and suppressing immune responses. In 1976 Murphy et al. and Tada et al. independently reported a phenomenon in mice called I-J. [17] [18] From the perspective of the symmetrical network theory, I-J is one of the most important phenomena in immunology, while for many immunologists who are not familiar with ...
This process – called "clonal expansion" – allows the body to quickly mobilise an army of clones, as and when required. Such immune response is anticipatory and its specificity is assured by pre-existing clones of lymphocytes, which expand in response to specific antigen (process called "clonal selection").
The term "idiotype" is sometimes used to describe the collection of multiple idiotopes, and therefore overall antigen binding capacity, possessed by an antibody. The word "idiotype" became influential in immunology when Niels Jerne formulated his immune network theory .
