Innate immunity
Natural killer cells = (a type of cytotoxic lymphocyte)
Phagocytes
Neutrophils
Monocytes
(then become) wandering Macrophages
Adaptive immunity
T-cells
Helper T-cells (activate all other leukocytes)
Cytotoxic T-cells
Virus:(kill pathogen and host cell or kill host cell and release pathogen for phagocytosis)
Pathogen cells with antibody kill)
B-cells
Produce antibodies to label pathogen, which:
Facilitate phagocytosis
Activate defensive proteins
Neutralise directly
