 are not (their clone, plasma cells are) | B cells ARE/ARE NOT effector cells |
| (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 ___. |
| ANTIBODIES | 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 ___. |
| IgG | Ig ___ class antibodies are the most abundant. |
| M | 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 ___ |
| IgM, plasma | 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 ___ |
| IgD, B | ___ class antibodies is the most important class in humoral immunity (because they activate ___ cells) |
| IgM | Ig__ is star shaped (pentamer - 5 units) |
| IgM | Ig__ are first antibody responders |
| IgD | Ig__ activated B cells |
| IgE | Ig___ located on mast cells, basophils and involved in allergic reactions and parasitic worms |
| IgA | Ig___ can be a monomer or dimer (2 unit) |
| IgA | Ig___ found mainly in saliva, tears, saliva, body fluids |
| IgA | Ig___ levels decrease during stress, lowering immunity |
| IgA | Ig___provide protection of mucous membranes |
| IgG, IgA (sometimes), IgD, IgE | Ig___ monomers |
| IgG | Ig__ do a LOT of things: enhance phagocytosis, trigger complement system, neutralize toxins, protects agains bacteria and viruses.... |
| IgG | Ig___ found in intestines |
| IgG | Ig___ main protection of newborns |
| IgE | Ig___ is most rare |
| IgM | Ig___ agglutinates and lyses microbes |
| IgM | Ig___ float around in blood as stars but are monomers on B cells |
| IgM | Ig___ are A and B blood antibodies |
