According to a study from the United States, "Cell-cycle control is a major determinant of homeostasis during B-cell development, differentiation, and tumorigenesis. The generation of an antibody response requires activation and expansion of antigen-specific B cells and terminal differentiation of these cells into plasma cells. Plasma cells arrest in the G1 phase of the cell cycle, but the mechanism that underlies timely cell-cycle entry and exit in the humoral immune response is not known.
