Activated helper ' cell releases cytokines when encounters a B cell that has previously combined with an identical antigen-bearing agent Antibodies bind antigen- -bearing agents, helping to destroy them Accessory cell. such as macrophage phagocy tizes antigen- -bearing agent and the macrophage's lysosomes digest the agent. Cytokines stimulate the B cell to proliferate. Antigen- -bearing agents enter tissues Antigens from the digested antigen- bearing agents are displayed on the accessory cell's membrane oell disnlawod anter displaved call
