During the mаturаtiоn оf B-cells, а series оf variable gene splicing events result in each B-cell being capable of synthesizing an antibody with a unique variable region. The entire population of B-cell is therefore capable of responding to any antigen of almost any shape. How does the immune system ensure that B-cells that have antibodies that react with host proteins do not cause the immune system to attack the body?
