(1) II, take the antigen in and make a MHC-ANTIGEN COMPLEX, (2) HELPER T, HELPER T, INTERLEUKIN-2
(1) B cells have MHC-___ self antigens. When a B cell is stimulated by the antigen it recognises, the first thing the B cell does it to ___. (2) Then a ___ cell is required for costimulation. The ___ cell does this by secreting ___
UNDERGOS CLONAL SELECTION, MEMORY B CELLS AND PLASMA CELLS
after costimulation a B cell ___. generating ___.
plasma cells secrete ___.
SHORT, RECENT INVASION
IgM class antibodies are ___ lived and therefore indicate a ___.
IgM, RECENT INVASION
Ig ___ class antibodies are short lived and therefore indicate a ___.
IgG (think GOOD for babies), IgA
Ig ___ class antibodies cross the placenta and Ig ___ class antibodies are in breast milk
PHAGOCYTES TO INGEST THEM
when an antibody agglutinates and precipitates antigens a clump forms, which makes it easier for ___.
Ig ___ class antibodies are the most abundant.
anti-A and anti-B (blood type) antibodies are class Ig ___.
IgG, IgE, IgD (think GED is a basic degree)
class ___ antibodies are monomers.
IgA, breastmilk, body fluids (think little boats with two oarsmen floating around in body fluids >--< )
class ___ antibodies are dimers or monomers and are found in ___ and other body ___
class ___ antibodies are polymers (like stars floating around) and are secreted by ___ cells
IgM, agglutination (precipitation)
___ class antibody type causes ___ which means clumping
IgD, IgM, clump, agglutination
(1) ___ class antibodies activate B cells. (2) ___ class antibodies are glutinators which means they ___ microbes a process called ___
___ class antibodies is the most important class in humoral immunity (because they activate ___ cells)
Ig__ is star shaped (pentamer - 5 units)
Ig__ are first antibody responders
Ig__ activated B cells
Ig___ located on mast cells, basophils and involved in allergic reactions and parasitic worms
Ig___ can be a monomer or dimer (2 unit)
Ig___ found mainly in saliva, tears, saliva, body fluids
Ig___ levels decrease during stress, lowering immunity
Ig___provide protection of mucous membranes
IgG, IgA (sometimes), IgD, IgE
Ig__ do a LOT of things: enhance phagocytosis, trigger complement system, neutralize toxins, protects agains bacteria and viruses....
Ig___ found in intestines
Ig___ main protection of newborns
Ig___ is most rare
Ig___ agglutinates and lyses microbes
Ig___ float around in blood as stars but are monomers on B cells
