______ activation happens when a naive B cell that is completely dependent on the assistance of helper T cells
This cell is a WBC that are stationed beneath the surface of exposed surfaces
The antigen that a given B cell receptors
This process results in a collection of B cells whose receptors have a higher average affinity for their cognate antigen
An antigen that binds to molecules on the B cell surface that are not B cell receptors, and brings these molecules together
_____ activation does not depend on the cognate antigen recognized by the BCR
A winning combination of gene segments
When BCRs are clustered together they are said to be ______
Describes the phenomenon of having the opposite effect of protection

_____ activation happens when a naive B cell is more or less independent of the helper T cell

This receptor makes B cells exquisitely sensitive to antigens, and have a dramatic effect on signaling
An antigen that causes an allergic reaction
When a B cell can change the class of antibody it produces
B cells that have never been activated by encountering their cognate antigen
