,Question 6
What is the B cell receptor?
Correct Answer
BCR
Question 7
Serum Amyloid A
Correct Answer
Binds to some TLR's leading to increased inflammation through increased cytokine
release
Question 8
Innate Immune system
Correct Answer
•Is the first line of defense against infections
•It works rapidly
•Gives rise to the acute inflammatory response
•Has some specificity for microbes
•Uses different receptors to recognize pathogens
Question 9

,Question 10
What are some gram + bacteria to know for this class?
Correct Answer
• Vacilles
• Streptococcus
• Staphylococcus aureus
• Mycobacterium
VSSM
Question 11
Most dendritic cells
Possess high levels of?
Correct Answer
Surface MHC class II molecules
Question 12
What cells create antibodies?
Correct Answer
B cells
Question 13

, Question 14
What happens during inflammation?
Correct Answer
•During inflammation, blood supply to the area increases, heat in the area will slow
the microbe reproduction, macrophages are there to help stop the pathogen
•The innate immune response starts first (this is determines by the genes you
inherited from your parents
-Adaptive cells (T and B change the genes for their receptors)
-Innate response consists of two parts
-Recognition
-Recruitment of effect mechanisms (cells)
Question 15
What is commensal bacteria?
Correct Answer
Over 1000 microbial species are in human gut (normal flora)
And they do not cause harm to the host
"commensal" = eat at the same table
Question 16
CR1 recognizes?
Correct Answer
C3b
Question 17

Correct Answer
Don't stain well
