I thought T-cells were educated in the thymus upon thymic epithelium and
not B-cells? Also, since each T- and B-cell has a clonotypic, rearranged
receptor, from which idiotopes may arise, wouldn't each T-cell have to
be tolerized against each B-cell idiotope? I don't see how that could be
possible.
