Cells and Immune System Flashcards
phagocytic cells
neutrophils
monocytes
macorphages
phagocytic cells release
inflammatory mediators
inflammatory mediators include
basophils
mast cells
eosinophils
natural killer cells include
complement proteins
cytokines
what is the main cell in adaptive immunity
macrophage
what does a macrophage start out as
monocyte
which presents antigen to T CELLS
what do macrophages produce
cytokines
natural killer cells
what is the importance of cytokines
can activate helper and cytotoxic T cells
kills pathogen or tumor cells
what can natural killer cells do
can inactivate pathogens
what is the main cell of adaptive immunity
T cell
trillions
what are the three types of T cells
killer T cell
helper T cell
regulatory T cell
kills virus-infected cells with/without antibody-> triggers target cells to “commit suicide”
Killer T cell
- help antigen recognition and regulation (helper and suppressor)
- secretes protein molecule called cytokines
- activates helper and killer T cells
- kills pathogen or tumor cell
helper T cell
helps other T cells keep “under control”
regulatory T cell
