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 .
[a] Clonal selection theory (CST): hematopoietic stem cells (1) differentiate and undergo genetic rearrangement to produce a population of cells possessing a wide range of pre-existing diversity with respect to antibody expression (2). Lymphocytes expressing antibodies that would lead to autoimmunity are filtered from the population (3), while ...
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 ...
Evolutionary art uses variation and selection to produce works of art; Evolutionary music does the same for works of music; Clonal selection theory sees the creation of adapted antibodies in the immune system as a process of variation and selection; Neural Darwinism proposes that neurons and their synapses are selectively pruned during brain ...
He repeats Busch experiments inoculating cancer patients with eryisipelas, noting tumor regression in many of them.

However, these discoveries, and the host of allograft experiments and observations of twin chimerism they inspired, were seminal for the theories of immune tolerance formulated by Sir Frank McFarlane Burnet and Frank Fenner, who were the first to propose the deletion of self-reactive lymphocytes to establish tolerance, now termed clonal ...
The goal is not to create cloned human beings (called "reproductive cloning"), but rather to harvest stem cells that can be used to study human development and to potentially treat disease. While a clonal human blastocyst has been created, stem cell lines are yet to be isolated from a clonal source. [14]
He made significant contributions to the clonal selection theory. [2] Career. Talmage was born to American Presbyterian missionaries in Japanese-controlled Korea.
