Immuno cells Flashcards
primary phagocytic cells
granulocyte/mononuclear cells
participate in antigen presentation and induction of immune system
macrophages
process of phagocytosis
chemotaxis, adherence, engulfment, phagosome formation and fusion, digestion and destruction
directly kills virus infected cells
T lymphocytes
wbc, defense against infection
leukocytes
produces y shaped antibodies
B lymphocytes
aka immunoglobulins that destroy antigens
antibody
foreign -fungi bacte or virus
antigen
antigen-allergies
allergen
antigenecity no protein substances
haptens
production of antibodies
inhalation or ingestion, response to infections, artificially injected (vaccines)
class of antibody found in mucosal areas and secretions that prevent colonization by pathogens
IgA
class of antibody that functions as an antigen receptor on B cells
IgD
class of antibody that binds to allergens and triggers histamine
IgE
class of antibody that composes the majority of antibody-based immunity
IgG
class of antibody that is expressed on B cell surface and secreted with high avidity
IgM
what is the structure of antibody
4 polypeptides 2 light chains 2 heavy chains
2 heavy chains are for
differences in class
2 lights chains are
kappa and landba, common in all classes
“natural antibodies” exists without intentional stimuli
environmentally stimulated antibodies
“unexpected antibodies” result of stimulation by antigen
immune antibodies
it is the response to antigen or foreign substance
immune response
4 phases of immune response
lag log plateau decline
test that detects presence and amount of antibody in blood
antibody titer
initial production of antibodies
primary immune response
production of antibodies after second exposure to antigen
secondary immune response
