chapter three Flashcards
what lymphocytes are in the immune response
t cells and b cells and natural killer cells
what are the two types of b cells
b memory cells and plasma cells
what cell produces antibodies
plasma cells
iga
aids in defense against proliferation of microorganisms in body fluids
igd
activation of b cell
ige
involved in hypersensitivity or allergic reactions
igg
major antibody in blood serum passes through placenta barrier, serves as first passive immunity for the newborn
igm
involved in early immune responses
antibody titer
level of antibody in blood
what are the four types of t cells
t helper, t suppressor, t cytotoxic, t memory
t helper cell
increases function of b cells has cd4 cell receptor
t suppressor cell
carries cd8 cell receptor shuts down cell-mediated immunity near end of immune reaction
t cytotoxic cell
carries cd8 and attacks virally infected and neoplastic cells
nk cell
attacks and destroys foreign cells as soon as they appear
what is the function of marcophages
antigen-presenting cell and messenger between inflammatory and immune response
function of dendritic cells
antigen-presenting cell and it acts as a link between innate immunity and acquired immunity
what is a type of dendritic cell
langerhans cell
function of cytokines
communication with other immune system cells
passive immunity
use of antibodies produced by another person to protect an individual
active immunity
uses antibodies produced by one’s own body to protect against infectious disease
what category is immunization/vaccine
acquired active immunity
what is the major lymphocyte involved in humoral immunity
b cell
what is the major lymphocyte involved in cell mediated immunity
t cells sometimes assisted with marcophages
type one hypersensitivity
reaction occurs immediately, and involves ige
type one hypersensitivity
reaction occurs immediately, and involves ige
type two hypersensitivity
aka cytotoxic hypersensitivity, involved igg and igm and results in the destruction of the tissue that has the antigen on it
type three hypersensitivity
aka immune complex hypersensitivity, immune complexes are forms and are dispersed to different types of tissue and neutrophils are attracted to that
type four hypersensitivity
aka cell mediated, reaction takes 2 - 3 days to develop
what is the most common reason for developing aphthous ulcers
trama
what cell is responsible for the ulcer
t cytotoxic cell
what is the most common aphthous ulcer
minor
where do aphthous ulcers appear
nonkeratinized oral mucosa that is not attached
what is an example of a type four hypersensitivity
allergic contact mucositis and dermatitis
what is an example of a type three hypersensitivity
fixed drug eruption
what age does erythema multiforme common occur
younger then 30
what is em major caused by
drug exposure
what is the most common location of lichen planus
buccal mucosa
what is the most common form lichen planus
reticular lichen planus
what are the three features in reactive arthritis or retier syndrome
arthritis, urethritis and conjunctivitis
what is the antigen present in reactive arthritis
hla b27
what other disorder is associated with sjogren syndrome
raynaud phenomenon
who does systemic lupus erythematosus affect more
women eight times more frequent than men
what is pemphigus vulgaris
breakdown of cellular adhesion between epithelial cells
what cells are present at separation
tzanck cell
primary immunodeficiencies
genetic origin
secondary immunodeficiencies
underlying disorder
