Epigenetic changes drive the fate of a B cell

B cells are the immune cells responsible for creating antibodies, and most produce antibodies in response to a pathogen or a vaccine. A small subset of B cells instead spontaneously make antibodies that perform vital housekeeping functions. Understanding how epigenetics spur these differences in such similar cells is an important fundamental question in immunology.
