BB Intro Flashcards
First line of Defense Immunity
Innate or Natural Immunity
Major players in Innate or Natural Immunity
Macrophages, Leukocytes, NK cells, complement alt pathway, cytokines
Acquired or Adaptive immunity major players
Lymphocytes (T & B cells), macrophages, antibodies, complement classic pathway
Cells responsable for production of antibodies
Activated B cells —> Plasma Cells
First antibody class produced by plasma cells
IgM. T cell stimulation can turn it to IgG
Most immunogenic blood group system
ABO (only major BGS)
Most immunogenic antigen outside of ABO and immunogenicity %
D , 50%
What percentage of proteins in the body are antibodies?
20%
Name the 5 different Immunoglobulin classes
IgA, IgD, IgE, IgG, IgM
Amino terminal regions in antibody structure
Fab
Carboxyl region of antibody structure
Fc
Fragment in antibody structure responsable for complement fixation
Fc region (carboxyl terminal/constant region)
Where does complement bing on IgG molecule? (CH?)
CH2
Where does macrophage bind on an IgG molecule? Ch?
CH3
IgG classes that are most likely to be clinically significant and why
IgG 1 and 3. Because they bind complement the best.
