CHAPTER 33 part 1 Flashcards
an inappropriate, often harmful response of the immune system to normally harmless substances
allergy
allergy is usually mediated by what type of antibody/immunoglobulins
IgE
the substances that causes the allergic response
allergens
refers to IgE-mediated diseases, such as allergic rhinitis
atopy
manifestation of tissue injury resulting from interaction between an antigen and an antibody
allergic reaction
series of events occurs in an attempt to render the invaders harmless, destroy them, and remove from the body
allergic reaction
a type of antibody that always RESPONDS to any event of EXPOSURE TO ALLERGEN
IgE
the first one to to respond in allergen
IgE
a chemical mediator that causes allergic responses to the body
histamine
this antibody helps TO THE PRODUCTION OF OTHER ANTIBODIES
IgD
this antibodies are responsible/seen especially in BODY SECRETIONS like saliva, colostrum
IgA
this antibody can be still present after few months/years
IgG
the largest antibody
IgM
the first antibody to react when THERE IS AN INFECTION
IgM
it is programmed to PRODUCE one specific antibody
b-cells
this cells secrete substances that ‘DESTROY target cell and stimulate macrophages’
t-cells
the cytotoxic cells
CD8
1st chemical produced by the immune system in response to allergens
histamine
responsible for pain sensation
prostaglandins
Srs-A
slow reacting substance of anaphylaxis
this PROMOTES SMOOTH MUSCLE CONTRACTION
srs-a
this cells stimulates production of plasma cells; involved in antibody production
b cells
the cytotoxic t-cells; ‘very common in destroying microorganisms’; stimulate macrophages
cd8
what are the primary chemical mediators:
histamine
eosinophil
platelet activating factors
prostaglandin
what are the secondary chemical mediators:
leukotrienes
bradykinin
serotonin
