Immune Concepts II
The main function of lymph nodes in the immune system.
What is to serve as filters where immune cells encounter antigens?
This type of hypersensitivity is exemplified by serum sickness.
What is Type III hypersensitivity?
This cell directly destroys virus-infected cells through perforin and granzyme release.
What is a cytotoxic T cell?
This is the mechanism for bacterial resistance in Rifampin and other DNA/RNA inhibitors.
What is mutation in RNA polymerase?
Varicella-zoster belongs to this virus family.
What is herpesviridae?
This cytokine type primarily promotes inflammation.
What is Tumor Necrosis Factor-alpha?
This immune mechanism underlies Type II hypersensitivity reactions.
What is antibody-mediated cytotoxicity?
This part of the antigen is recognized by an antibody.
What is the epitope?
Multidrug-resistant tuberculosis (MDR-TB) is defined by resistance to these two drugs.
What is isoniazid (INH) and rifampin?
Chronic infection is most commonly caused by this hepatitis virus.
What is HBV?
This is what pattern recognition receptors (PRRs) are responsible for.
What is detecting pathogen-associated molecular patterns?
This immunologic finding characterizes systemic lupus erythematosus.
What is immune complex deposition?
This antibody is mainly produced in a primary immune response.
What is IgM?
This is the target site for aminoglycoside antibiotics.
What are ribosomes?
Viral families differ by replication enzyme requirements. Negative-sense RNA viruses must carry this.
What is RNA polymerase?
This complement pathway is activated directly by antibodies.
What is the classical pathway?
This antibody mediates Type I hypersensitivity reactions.
What is IgE?
For full T cell activation TCR-MHC binding and this signal is necessary.
What is co-stimulatory molecule interaction?
M protein is a virulence factor of this gram positive cocci.
What is Streptococcus pyogenes?
The goal of NRTIs is to inhibit this.
What is reverse transcriptase?
This is the description of passive immunity.
What is administration of pre-formed antibodies?
This is the underlying immunologic process in contact dermatitis.
What is delayed T-cell medicated hypersensitivity?
This produces T cell receptor diversity.
What is recombination of V(D)J gene segments?
This color pigment is characteristically produced by Pseudomonas aeruginosa.
What is blue-green?
What is flaviviridae?
