How is naive B cell activated?
B cell activation. When naïve or memory B cells are activated by antigen (and helper T cells—not shown), they proliferate and differentiate into effector cells. The effector cells produce and secrete antibodies with a unique antigen-binding (more)
What are the steps of B cell activation?
Activation of B cells
1A B cell becomes activated when its receptor recognizes an antigen and binds to it. 2Most antigens are T-dependent. 3Interaction with antigens causes B cells to multiply into clones of immunoglobulin-secreting cells. 4The process just described takes place among the circulating B lymphocytes.
Where are naïve B cells activated?
The Extrafollicular Reaction. Naïve B cells generated in the bone marrow (BM) reside in lymph nodes until they encounter a protein antigen to which their specific surface IgM receptor binds.
Helper T cells stimulate the B cell through the binding of CD40L on the T cell to CD40 on the B cell, through interaction of other TNF-TNF-receptor family ligand pairs, and by the directed release of cytokines.
