Like T cells, B cells require multiple signals for activation. Antigen binding to the B cell antigen __________provides one signal

Like T cells, B cells require multiple signals for activation. Antigen binding to the B cell antigen __________provides one signal, while antigen-specific effector ________ provide the other signals. The requirement for multiple signals to activate either a T cell or a B cell helps to prevent _______ and dangerous activation of _________ , including __________ _________. Most of the proteins involved in cell–cell recognition and antigen recognition in the immune system, including _________ , TCRs, and _______ proteins, as well as various co-receptors,...

List the sequence of activities that a B cell undergoes after activation to a protein antigen. Begin with the process o f activation of a B cell (specifically identify each step in activation), then continue until after the centrocyte has interacted with the follicular dendritic cell and follicular helper T cell and has made plasma and memory cells. These memory and effector B cells make IgA antibody.
