The host defense function of a macrophage

bone marrow and thymus

the primary or central lymphoid organs in humans are the

T cells

cells classed with adaptive immunity

IgG & IgM

antibodies capable of binding complement and initiating classical complement pathway

type of heavy chain

determines the immunoglobulin class (isotope)

DR, DQ, DP

Class II (MHC) Ag refer to _________ regions

Diapedisis

movement of neutrophils out of the blood.

-Increased blood supply to the area
-migration of WBC
-appearance of acute phase proteins
-redness and swelling

Process of inflammation

Any protein

Most immunogenic

hybridomas

monoclonal antibodies are produced commercially by:

All nucleated cells

HLA antigens found on:

Monocytes

macrophages are large phagocytes present in the tissues. Derived from:

Ag complexed with MHC proteins

T helper cells recognize:

easily crystallizable

Fc fragment of the Ab molecule:

MHC

each person is a unique "self" determined by:

complement fixation

C1 binds to IgM to a bacterial cell surface:

IgM & IgD

found on the mature B Cell

exits in unrelated plants or animals

Heteroantigen is one that:

binding to antigen

Fab fragment of the antibody is capable of:

an antibody that reacts with a single epitope of an antigen

Monoclonal antibody

bacteria

the alternative pathway is activated by:

recognized as nonself

for a substance to be immunogenic, it must be:

alloantigens

human blood type antigens A, B & D are examples of:

Opsonization

in complement cascade, C3 is cleaved into C3a and C3b. C3a is released into circulation but C3b attaches to the cell surface. Which activity is associated with C3b?

IgG

75-80% of circulating Ab

IgM

structure of Ab in plasma includes a joining chain

IgA

most common hereditary immunodeficiency

Chromosome 6

MHG genes are located on:

B cell

don't form rosettes with unsensitized sheep rbc

hapten

antigenic only when coupled to a carrier

T helper cells

release cytokines

CH50

initial screen for classical pathway deficiency

Cytokines

Interlukin 2 (I-2) functions to stimulate T cell proliferation

humural immunity

neutralization of bacterial toxin by antibody

antibody

macrophage

antibody

immunoglobulin

antigen complexed with MHC proteins

the helper cells recognize

Gamma

Heavy chain in IgG

binds to hemoglobin

the function of the acute phase protein haptoglobin

CRP

this acute phase protein is capable of activating the classical pathway of complement

CD4

HIV virus infects this cell

MHC

each person in a unique self determined by their:

CD2 & CD3

both helper and cytotoxic T cell display these markers

elevated during immune response

acute phase protein

complement fixation

C1 binds to IgM that is bound to a bacterial cell surface...this is called

IgG

crosses the placenta

C3

which complement is presented in the greatest quantity

B cell

precursor to plasma cell

natural killer cell

nonspecific killer of tumor cell

kappa and lambda

light chain is made up of:

C3b

opsonization

IgG

present in highest titer during an anamnestic (secondary) response

IgM

most efficient at agglutination

IgA

found in tears, saliva, colostrum

IgM

which is the structure of the antibody in plasma that includes a J or joining chain

IgA

the most common immunodeficiency

IgG

four subtypes of this antibody

IgM

has 10 binding sites

IgG

titer of this antibody would show that vaccination was successful

Monoclonal light chains

Bence Jones proteins are

2 Fab & 1 Fc

treatment with Papain cleaves IgG into 3 fragments

cow pox generates to small pox

cross immunity

natural immunity

natural killer cells

molecular patterns associated with pathogens

dendritic cells recognize self by focusing on:

C5b6789

which of the following is the membrane attack complex of the complement pathway

IgM

which antibody is best at fixing (activating) complement

Neisseria infections

hereditary deficiency of late complement components (C5,C6,C7, or C8) can be associated with which condition

Fc

complement binds to the _________ area of the antibody

properdin

a component associated only with the alternative pathway of complement activation is:

opsonin

C3b coats foreign cells or organisms, tagging them and making the more easily phagocytize. Therefor we can call C3b a(n):

is a measure of total complement activity in the classical pathway

the serum hemolytic complement level (CH50):

C1qrs

which is the "recognition unit" in the classical complement pathway

C4b, C2a

which is the "C3 activation unit" in the classical complement pathway

IgG

crosses the placenta to provide the newborn with passive immunity

IgM

strong agglutination reaction at room temp

IgE

involved in allergic reactions

IgM

the first antibody to be produced in an immune response

IgG or IgM

one of the two antibodies that can fix (activate) complement by the classical pathway
