intro to immunology Flashcards
research
yellow fever vaccine
max theiler
identify
- capable of destroying tissue invading helminthes
- regulates inflammation
- regulate mast cell function & cytokine production
- capable of phagocytosis
- dark-purple nucleus
- pink-blue cytoplasm
- reddish-orange granules
eosinophils
tissue macrophages
spleen - (?)
littoral cell / splenic macrophage
identify
- phagocytize antigen and present it to T-helper cells
- covered w/ long membranous extensions
- most potent phagocytic cell & antigen presenting cell
dendritic cell
identify
- must meet or primed by an initial exposure to a specific antigen
- has slow reaction
- it recognizes particular pathogen
- need prior exposure
- can remember on how they kill microorganism
adaptive immunity
tissue macrophages
kidney - (?)
mesangial macrophage
identify whether is it 1st, 2nd or 3rd line of defense
- skin
- mucous membrane
- skin secretions
1st line
research
antihistamine research
daniel bovet
host immunity
- immune system responds to an altered organism / non-infectious organism
- immunity acquired by injection of synthetic or biological prapartaions such as vaccine
artificial active
identify
- no action involved
- the body or person merely receives antibodies
passive immunity
identify
he showed quantitative measurement of immune reaction
paul ehrlich
research
immunoregulation, monoclonal antibody
jerne, koehler, milstein
research
structure of antibodies
gerald edelman, rodney porter
identify
3 groups of PRRs
- secreted PRRs
- phagocytosis receptors
- toll like receptors
identify
an immunity that is given by non-cellular substances (antibody)
humoral immunity
identify
- 1st to migrate
- short-lived
neutrophils
identify
- amplify reactions that start w/ the mast cell at the site of entry of antigen
- granules contain heparin and histamine
- dark-blue to blue granules
basophil
identify
substances produces in response to antigenic stimulation that is capable of specific interaction w/ provoking antigen
antibody
identify
- can degranulate when membrane-bound IgE binds an allergen
- binds to IgE in hypersensitivity reaction and non-phagocytic
- acts as gatekeepers
- round, dark-purple nucleus
- dark-blue cytoplasm
- 9-18 mos life span
mast cells
research
serum antitoxins
emil von behring
identify
increases blood flow and brings phagocytes and other WBCs to the area (redness and heat)
vassodilation
identify
allowing fibrinogen and complement to enter the tissue from the blood (swelling and pain)
increased vascular permeability
identify
loosely binds circulating leukocytes & cause them to roll along the vascular wall
selectins
chemotaxis
- excreted by leukocytes
- influenced by opsinins
postive chemotaxis
identify
he awarded as the 1st immunology-related nobel prize for his works on serum therapy
emil von behring
tissue macrophages
placenta - (?)
hoff bauer cell
identify
exposure to one agent produces protection against another agent
cross immunity
research
phagocytosis
elie metchnikoff
tissue macrophages
CNS tissue - (?)
microglial cells
identify
- antibody mediated
- B lymphocyte
- acts against extracellular pathogen
- antibody-dependent cell mediated cytolysis (ADCC)
humoral
identify
function as host defense peptides
defensin
tissue macrophages
lungs - (?)
alveolar macrophage / dust cell
v
skin - (?)
langerhans cell
tissue macrophages
connective tissues
histiocytes
identify
- 2nd to migrate
- long-lived
monocytes / macrophages
identify
are membrane spanning glycoproteins that share a common structural element called leucin rich repeats (LRRs)
toll like receptors
research

cell surfaces
identify
clears segments of bacterial cell wall w/o the benefit of O2
protease & defensins
identify
father of modern microbiology
louis pasteur
identify
ability to remember previous substances
memory
identify
its major function is to recognize “self” from “nonself”
immune system
research
transplantation
edward donnall thomas, joseph murray
identify
functions as opsonins
