Each cell in the immune system has a specific function and role
There are many types of T cells in the immune system.
Here are two of them:
Helper T cells:
Respond to peptide antigens displayed on antigen-presenting cells
Stimulate the activation of nearby B cells and cytotoxic T cells (This is an example of
cell communication
)
Cytotoxic T cells:
Effectors of cell-mediated immunity
Eliminate body cells infected by viruses and intracellular pathogens: transplanted cells
There are also many types of B cells.
B cells:
Have to be stimulated by both an antigen and cytokines to start functioning and function properly
Proliferate and differentiate into a clone of an antibody
