- BFalso
5Order of events in infection
1: [blank_start]Entry of Pathogen[blank_end]
2: Recognition of Pathogen
3: Phagocytosis and killing of pathogen
4: inflammation induction
5: attraction of cells to infections site
6: Pathogen elimination an/or adaptive immunity activation- AEntry of Pathogen
6What function do phagocytes not preform

- BFalso
9NK cells kill virus infected and tumor cells in a SPECIFIC fashion
- AVerdadero
- BFalso
10Activites of the NK complement are all except which?

14The ability of the immune system to recognize pathogens is not dependant on antibodies.
- AVerdadero
- BFalso
15Antibodies can have one of 5 isotype, and a number limited pathogen binding domains
- AVerdadero
- BFalso
16The mechanism between AB diversity and T cell receptor diversity is virtually identically
- AVerdadero
- BFalso
17Generation of antibody diversity comes from having multiple immunoglobulin genes as well as recombinatorial associations (called somatic recombination).
- AVerdadero
- BFalso
18With respect to immunology V stands for [blank_start]variable[blank_end], D stands for [blank_start]diversity[blank_end], J stands for [blank_start]joining[blank_end], C stands for [blank_start]constant[blank_end]
- Avariable
- Bdiversity
- Cjoining
- Dconstant
19The light chain consists of the [blank_start]V[blank_end] and [blank_start]J[blank_end] regions. The heavy chain consists of the [blank_start]V[blank_end], [blank_start]J[blank_end], and [blank_start]D[blank_end] regions.
- AV
- BJ
- CV
- DJ
- ED
20Once genes for a variable region are rearranged, they can be rearranged further for the life of the cell
- AVerdadero
- BFalso
21What does clonal selection do?
- Aproduce WBC to fight a specific pathogen
- Bproduce WBC to fight pathogens nonspecifically
- Csuppress immune function, post infection
- Dsuppress the inflammatory pathways
22Naive B cells display these two antibodies.,
- AIgM, IgD
- BIgM, IgE
- CIgD, IgE
- DIgA, IgG
- EIgG, IgM
23For Somatic Recombination which enzyme performs the major DNA function
- ARAG proteins
- BAID proteins
24Omenn syndrome is a RAG deficiency what does this cause?
- Ahypersomatic recombination
- Bminimal somatic recombination
25What is isotype switching?
- Achanges specificity to specific antigen
- Bchanges classification of specific antibody
- Cchanges the type of cell
- Dchanges the the CD40L to the B9.
26affinity maturation is the process that leads to increased affinity of antibodies for a particular antigen as a result of somatic mutation in the Ig genes followed by selective survival of B cells producing the antibodies with the highest affinity.
