b cell activation requires quizlet

What are the steps of B-cell activation quizlet?
Q-Chat
antigen recognition-B cell exposed to antigen and binds with matching complementary.antigen presentation-B cell displays epitope, Helper T cell binds secretes interleukin.clonal selection= interleukin stimulates B cell to divide.differentiation=become memory or plasma cells.attack- plasma cells secrete antibody.
Which of the events are required for B-cell activation?
To become activated to produce antibodies, B cells must first recognize specific antigen through the B-cell receptor (BCR).
This specific binding event initiates intracellular signaling leading to altered gene expression, reorganization of the B-cell cytoskeleton, and antigen internalization.
B cells are activated by two temporally distinct signals, the first provided by antigen binding to the B cell antigen receptor (BCR) and the second by T helper cells.

What does B-cell activation require?

B-cell activation by many antigens, especially monomeric proteins, requires both binding of the antigen by the B-cell surface immunoglobulin—the B-cell receptor—and interaction of the B cell with antigen-specific helper T cells.

B cells: B cell activation requires two distinct signals, and results in B cell differentiation into memory B cells or plasma cells. The first activation signal occurs upon antigen binding to B cell receptors (BCRs).
