Preface After an infection or after deliberate immunization, high-affinity antibody-secreting plasma cells and memory B cells are generated that are able to provide protection against subsequent infection. The production of these effector cells occurs in a specialized microenvironment called the germinal center. The main cellular constituents of the germinal center are rapidly dividing B cells, which are subjected to somatic hypermutation of their immunoglobulin variable region genes. This process can change the affinity, or alter the specificity, of the B cell receptor for antigen which means that newly mutated B cells must undergo a process of selection to ensure that the germinal center p
