Question

If an immature B cell binds to a multivalent self antigen after the cell has emerged from the bone marrow, then it ________________.

a) differentiates into a plasma cell
b) becomes a mature b cell
c) undergoes cell division, a process called clonal expansion
d) dies by apoptosis or becomes inactivated

Answer 1

If an immature B cell binds to a multivalent self antigen, it dies by apoptosis or becomes inactivated.

Step-by-step explanation:

If an immature B cell binds to a multivalent self antigen after the cell has emerged from the bone marrow, then it dies by apoptosis or becomes inactivated. This is because the binding of a self antigen indicates that the B cell has the potential to attack the body's own cells, which can lead to autoimmune responses. To prevent this, the immune system eliminates or inactivates self-reactive B cells.
