The normal flora on the skin, GI tract, and urogenital tract are a type of what defense?
Type of immunity that is highly specific, has memory, slow, and improves
Type of immunization that has a new immune response, delayed protection, memory, and occurs naturally with infection
Cell Type that HIV affects
How are engulfed bacteria killed?
Type of selection of T cells where there is strong recognition of either Class I or Class II MHC peptide. 95% of thymocytes die via this process.
Neutrophils that are directed to site of infection by interactions between what molecule
Name an example of Live attenuated vaccine
A kinase involved in signaling of IL-2
What adhesion molecules are required for tight binding of neutrophils?
Reaction catalyzed by TdT (terminal deoxy transferase)
APC that capture antigens by phagocytosis of pathogens
Allows for assessment of lymphocyte subpopulations
Workhorse of lab diagnoses used for detecting antigens or antibodies to antigens.
Type of interaction where antigen activated B cells present antigen to helper T cells
How do peptides bind to MHC?
Acute phase proteins in acute infection. Part of the innate immune response.
Compounds that are only immunogenic when attached to a larger molecule, called a carrier
Part of the antigen that antibodies and T cells physically bind to
Type of selection where T cells must be able to recognize self MHC or die.
Attract leukocytes into sites of tissue damage or infection
This type of exclusion gives homogenous B cell receptors with high avidity binding
APC that captures antigens via cell surface antibody molecules
Most immunogenic route of immunization
Kills tumor and virally infected cells. Does not undergo TCR or Ig rearrangement.
Enzyme that mediates Isotype class switching.
Where positive and negative selection occur
Type of immunization that has no new immune response, provides immediate protection, and has no memory or secondary response
Group of serum proenzymes that are activated by antigen bound Ig or by membrane components of Gram negative bacteria or fungi
State of immunologic inactivity
The only approved adjuvant for humans that turns a soluble protein into a particle and makes it easier to phagocytize by APCs
Name an example of a toxoid vaccine
Antigens containing more than 1 epitope
Which is the best antigen- protein, carbohydrate, or lipid?
Name a type of cancer prevented by vaccines.
What adhesion molecules are required for rolling of neutrophils?
Class of Ig involved in complement system activation
Class of Ig that cross the placenta
Type of T cells found in skin and mucosal tissues that kill bacterially-infected cells
Phosphatase that activates the transcription factor NFAT
The process by which peptides are generated from larger polypeptides
Pattern recognition molecules that sense different microbial products
Name an example of a subunit or recombinant vaccine
APC that capture antigens by endocytosis
Class of Ig that mediates allergic reaction and involved in sensitization of mast cells
Name a potent anaphylotoxin?
Activates the NFkB
Where somatic hypermutation, class switching, and affinity maturation are occurring
What do T cells see?
This increases with repeated antigen exposure
WBC count >12000 is a sign of what?
Type of immunity that is non-specific, no memory, fast, and constant
Region of antibodies that contains antigen binding sites.
Terminally differentiated B cells that make lots of IgG
An increase in the number of immature neutrophils. A sign of infection
Class of MHC found on APC only.
Type of IFN secreted by Th1 that upregulates MHC Class I and II and activates macrophages to become highly microbiocidal.
Name an example of a killed vaccine
Marker for B cells that is targeted for therapy in lymphoma and autoimmune diseases
Class of Ig that crosses epithelial surfaces by the use of poly-Ig receptor
