|
|
Clinal Selection |
• The activation f specific B & T cells • Activates complex series of events leading production of antibodies |
|
|
Cytokines |
• The hormone-like chemicals that stimulate and coordinate the whole series of events • Stimulate the differentiation of macrophages, B & T cells. |
|
|
T Helper Cells |
• Release cytokines that stimulate B cells to develop • Stimulare phagocytosis |
|
|
T Killer cells (Tk) |
• Attack and kill host body cells that display foreign antigens |
|
|
T Memory cells ( Tm) |
• Provide long-term immunity |
|
|
T Regulator Cell (Tr) |
• **** down the immune system after pathogen has been successfully removed • Involved in preventing autoimmunity |
|
|
