What does it mean for an immature B cell to be clonally ignorant? They have never undergone clonal expansion. They express both IgM and IgD. They have migrated out of the bone marrow. They have bound self-antigen, but the antigen didn't cross-link BCRs. They have not encountered antigen that can bind their BCR. Question 8 For thymocytes, negative selection involves... high affinity interaction with antigen in the context of MHC double positive cells deletion of self-reactive antigen-presenting cells elimination of T cell-independent antigens clonal expansion Question 9 Double-positive B cells express... CD4 and CD8 BCR and TCR CD28 and CD40 All of the above are correct None of the above are correct
