- AB B cells are an abundant population of lymphocytes that can efficiently
- capture, process, and present antigen for recognition by activated or
- memory T cells. Controversial experiments and arguments exist, however,
- as to whether B cells are or should be involved in the priming of virgin
- T cells in vivo. Using B cell-deficient mice, we have studied the role
- of B cells as antigen-presenting cells in a wide variety of tests,
- including assays of T cell proliferation and cytokine production in
- responses to protein antigens, T cell killing to minor and major
- histocompatibility antigens, skin graft rejection, and the in vitro and
- in vivo responses to shistosome eggs. We found that B cells are not
- critical for either CD4 or CD8 T cell priming in any of these systems.
- This finding lends support to the notion that the priming of T cells is
- reserved for specialized cells such as dendritic cells and that antigen
- presentation by B cells serves distinct immunological functions.
