Germinal centers or germinal centres (GCs) are transiently formed structures within B cell zone (follicles) in secondary lymphoid organs – lymph nodes, ileal Peyer's patches, and the spleen – where mature B cells are activated, proliferate, differentiate, and mutate their antibody genes (through somatic hypermutation … See more There are several key differences between naive B cells and GC B cells. Naive B cells do not undergo lots of cell division. On the other hand, B cells in GC B cells tend to divide rapidly and frequently, and they can have cell cycles as … See more There are two distinct regions of the germinal center: the light zone (LZ) and the dark zone (DZ). These two zones are formed from pre-GC B cells that proliferate and polarize seven … See more There are T helper cells in the follicles of the lymph nodes called T follicular helper cells that promote germinal center formation and the … See more Following positive selection, there are three possible fates for B cells undergoing the germinal center reaction: become a plasma cell, become a memory B cell or enter into the dark … See more Germinal centers are initiated in the B cell follicle of the lymph node. Following activation of naive B cells in the lymph node follicles, the B cells migrate to the interfollicular areas so that they can interact with T cells. When the B and T cells interact, the … See more 1. Within lymph nodes, mature peripheral B cells known as follicular (Fo) B cells acquire antigen from FDCs and in turn present it to cognate CD4+ TFH cells at the border that demarcates the interfollicular T cell area and B cell zone (also known as lymphoid follicles).
