Which immunoglobulin class would be most effective in preventing a respiratory virus from attaching to cells in the respiratory tract?
IgA
Why is X-linked hyper-IgM syndrome more prevalent in males?

Which process is directly related to the activity of activation-induced deaminase (AID) in B cells?
Isotype switching
What determines the heavy-chain isotype produced by a B cell during an immune response?
The cytokines produced by follicular helper T cells
What is the fate of plasma cells that produce high-affinity antibodies following an immune response?
They become plasmablasts that migrate to bone marrow and mucosal tissues.
What mechanism provides feedback inhibition of antibody production in B cells?
The binding of antibodies to the FcγRIIB receptor
Test your knowledge on immunoglobulins and B cell activities with questions about preventing respiratory viruses, X-linked hyper-IgM syndrome, activation-induced deaminase, and heavy-chain isotypes production.
