1. Multiple choice: Self-reactive B cells can be eliminated from the repertoire at several stages of B cell maturation, including immature B cells that have already emigrated from the bone marrow into the circulation. This latter stage of tolerance induction is critical because: A. Not all self-antigens are expressed or present in the bone marrow during B cell development. B. Immature circulating B cells are more sensitive to antigen stimulation than the developing B cells in the bone marrow. C....
