The generation of diversity

Description

A major problem for immunologists had long been to determine how cells of the immune system could produce millions of distinct antibodies - and produce them on demand. The clonal selection theory explains that cells with genetic instructions to produce each antibody exist in the body in small numbers until exposure to the right molecule - the antigen - triggers the selective cloning that will reproduce the required cells. But how can so many different antibody-producing cells be generated from such limited genetic material? The solution to this question came from new applications of molecular biology, and, as the authors argue, the impact of the new techniques changed both the methods and the concepts of immunology. The Generation of Diversity is an intellectual history of the major theoretical problem in immunology and its resolution in the post-World War II period. It will provide for immunologists essential background for understanding the conceptual conflicts occurring in the field today.
