Immune Concepts
The immune cell that is primarily responsible for engulfing and digesting pathogens.
What is a macrophage?
The function of MHC Class I molecules.
What is to present endogenous peptides to cytotoxic T cells?
This is the main goal of vaccination.
What is to generate immunologic memory?
This part of an antigen is recognized by an antibody.
What is the epitope?
This antibody mediates Type I hypersensitivity reactions.
What is IgE?
Where T cells undergo maturation.
What is the thymus?
This type of T cell recognizes peptides presented by MHC Class II molecules.
What are CD4+ helper T cells?
This type of vaccine uses a weakened form of the pathogen.
What is live-attenuated vaccine?
This antibody is primarily produced in a primary immune response.
What is IgM?
Contact dermatitis results from this immunologic process.
What is delayed T-cell mediated hypersensitivity?
The main consequence of a deficiency in the complement system.
What is increased susceptibility to bacterial infections?
This cell directly destroys virus-infected cells through perforin and granzyme release.
What is a cytotoxic T cell?
This is how herd immunity helps prevent infectious disease spread.
What is by lowering the number of susceptible hosts?
This is where B-cell maturation begins.
What is bone marrow?
This is the main risk associated with prolonged immunosupression therpay.
What is increased infection and malignancy risk?
The primary function of the immune system.
What is to protect the body against pathogens and foreign substances?
This is the main reason MHC compatibility is critical in transplantation.
What is because it ensures graft recognition as self?
This type of vaccine contains an inactivated toxin.
What is toxoid vaccine?
This is the main function of plasma cells.
What is antibody secretion?
This type of immunodeficiency results from HIV infection.
What is secondary acquired?
How innate and adaptive immunity differ.
What is Innate immunity provides non-specific defense, while adaptive immunity is specific
This happens if a T cell binds strongly enough to a self-antigen during negative selection.
What is apoptosis?
This is the main purpose of booster vaccines.
What is to strengthen and prolong immune memory?
This immunoglobulin is most abundant in mucosal secretions.
What is IgA?
This vaccine type contains only parts of a pathogen, such as proteins or polysaccharides.
What is a subunit vaccine?
