They are uniquely found predominantly at the border of the T cell zone that merges with the B cell follicles and germinal centers. Pre-TFH cells are functionally very similar to other TFH cells in facilitating germinal center B cell reactions however, in addition, they are also capable of driving follicular B cell development adjacent to and outside of germinal centers to produce quic…
