First line of defense against infections Innate Immunity
Three components of the innate system Physical barriers, circulating cells, circulating proteins
What are physical barriers? Skin and mucus
Circulating Cells Neutrophils, macrophage, dendritic cells, natural killer cells, mast cells, eosinophils, basophils
Circulating Proteins Lysosyme, complement system
What is the most important barrier to infection? Skin
Other barriers to infection Respiratory, urinary, GI tract
What do goblet cells secrete? Mucin
What are leukocytes? White Blood cells
What cells are non-lymphocytes? B&T Cells
Granulocytes Neutrophils, Basophils, Eosinophils
Agranulocytes Monocytes, macrophage, dendritic cells
Which WBC is the most abundant in mammals? Polymorphonuclear cells, attraction to infection, target extracellular pathogens (bacterial) mechanism of protection- phagocytes, degranulation, NETS Neutrophils
Takes up basic dye, releases histime during inflammatory response, helminths, degranulation, binds to IGE antibodies Basophils
Orange stain, fights parasites and viral infections, degranulation (modulates)Reactive oxygen- species and paradoxides Eosinophils
Differentiate into macrophage or dendritic cells, kidney shaped nucleus, involved in phagocytosis, antigen presentation, and cytokine production Monocytes
Found in blood and tissues, phagocytosis of pathogens, cytokine-chemical signals that modulate the immune response Macrophages
