Within germinal centers, TFH cells play a critical role in mediating the selection and survival of B cells that go on to differentiate either into long-lived plasma cells capable of producing high affinity antibodies against foreign antigen, or germinal center-dependent memory B cells capable of quick immune re-activation in the future if ever the same antigen is re-encountered.

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 quickly responsive but non-durable plasma cell-driven antibody responses (known as the extrafollicular response). And you can do a few things to keep from getting hepatitis B or C, which cause 80% of liver cancer cases.
