Steps in antibody production

Question 1

Describe the 7 steps for T cell activities

Answer 1

Antigen-bearing agents enter tissues.
An accessory cell, such as a macrophage, phagocytizes the antigen-bearing agent, and the macrophage’s lysosomes digest the agent.
Antigens from the digested antigen-bearing agents are displayed on the membrane of the accessory cell.
Helper T cell becomes activated when it encounters a displayed antigen that fits its antigen receptors.
Activated helper T cell releases cytokines when it encounters a B cell that has previously combined with an identical antigen-bearing agent.
Cytokines stimulate the B cell to proliferate, enlarging its clone.
Some of the newly formed B cells give rise to cells that differentiate into antibody-secreting plasma cells.
