September 5th

Born on September 5, 1939.
Japanese molecular biologist and immunologist, who was awarded the 1987 Nobel Prize in Medicine or Physiology for his fundamental discovery of the genetic principle that produces diversity. antibodies in the body. Antibodies are produced by a special type of white blood cell called a B lymphocyte. In a pioneering study, Tonegawa was able through a series of ingenious experiments to show how parts of the genome of the cell redistributed under its differentiation from embryonic cells to antibodies that produce B lymphocytes. Thus, he finally answered the question of how the genetic material in B cells can be may be enough to generate the structure of a seemingly endless number of different antibodies.
