Innate lymphoid cells reside primarily in tissues such as the lungs, the lining of the gastrointestinal tract, and the skin, because these sites represent the major routes of entry of pathogens into the body.
Several different subsets of innate lymphoid cells exist, and each is specialized to respond to a category of pathogen (e.g., viruses, extracellular bacteria, helminthic parasites, etc).
a) True
b) False
The correct order of words to describe how innate
immune response responds to a pathogen that has
gotten by the physical and chemical barriers is:
À) Skin, Saliva, Cytokines, Macrophage
B)Macrophage, Cytokines, Neutrophil, Natural Killer
Cell
C) Neutrophil, Cytokines, Killer T Cell, Antibodies
D) Antigen, Macrophage, B Cell, Killer T Cell
Which of the following lists contains cells that are typically considered to be associated with the innate immune response?
Question 14 options:
A)
neutrophils, macrophages, T cells
B)
neutrophils, macrophages, NK cells
C)
B cells, T cells, and NK cells
D)
