Explain the following statement: "Both bacteria and viruses
can use similar mechanisms to evade the immune
response."
Draw a figure illustrating the sequence of events in a typical inflammatory response to a bacterial
infection caused by injury to the skin (in 3 main stages).
Include a note at top of figure: Is this an example of an innate response or adaptive immune response?
Include the following structures/cells/chemicals: epidermis, dermis, splinter contaminated with bacteria
puncturing skin, macrophages, mast cells, neutrophils, nitric oxide (as blue dots), endothelial cells lining
capillary, red blood cells within capillary, histamine (as green dots).
Under each stage, describe the events occurring in the 3 main stages:
Stage 1: What do mast cells and endothelial cells produce in initial response to injury? What do the
chemicals produced by the cells do?
Stage 2: What happens to capillaries? What leaks out of capillaries to enter the site of the wound?
Stage 3: What do neutrophils and macrophages do? What happens to capillaries at this point?
Match each of the listed characters below to the innate or adaptive immune system.
1) Fully formed at birth
2) Includes barrier tissues and macrophages, among other defenses.
3) Recognizes molecular patterns that are shared across many pathogens.
4) Serves as the first line of defense.
5) Continues to develop with exposure to new pathogens.
6) Recognizes specific (unique) pathogen peptides.
7) Includes a 'memory' that leads to immunity by recognizing threats that have previously invaded the body.
8) Involves T cells, B cells, and antibodies.
Here is the options:
a) innate immune system.
b) adaptive immune system.
