| abstractText | Ag, in the form of immune complexes retained on follicular dendritic cells, has been implicated in the development and maintenance of B cell memory. We addressed this question using a H chain transgenic (Tg) mouse model that lacks secreted Ig (mIg), and thus does not deposit Ag-containing immune complexes. We compared the ability of the mIg strain and a control Tg strain, which secretes IgM, to develop and maintain long-lived memory cells. After immunization, there was an increase of Ag-specific B cells in both strains that was maintained for at least 20 wk. We labeled the long-lived Ag-specific cells with BrdU and found that this population was similarly maintained. In addition, both Tgs were able to maintain a functional memory response as measured by secondary germinal center reactions. Our studies indicate that localization of Ag on follicular dendritic cells is not necessary for development and maintenance of B cell memory. |
