Receptors on Th cell is complementary to antigen and so it binds
This stimulates rapid Th cell mitosis :
Phagocytes are stimulated
Stimulates B cell division
Become memory cells
Activite cytotoxic T cells

Answer 4

Cytotoxic T cells destroy infected cells
Secrete perforin
Creates holes in cell membrane, destroying it
