Figure 42.11 Which of the following statements about T cells is false? Helper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. The T cell receptor is found on both CD4+ and CD8+ T cells.
When describing cytokines which statement is false? Group of answer choices Cytokines can be used as therapeutics to treat viral infections Cytokines help stimulate and modulate the function of the immune system Affecting cytokine production with drugs never puts the patient at risk Cells can produce cytokines to autostimulate and/or attract immune cells Drugs can prevent cytokine production
Which of the following is true about innate immune system? Check all that apply. PAMPs recognize pathogen recognition receptors (PRRs) such as TLRs, NLRs and RLRs present on/in host cells TLRs that are expressed on cell surface are mostly recognized by viruses, whereas intracellular TLRs are recognized by bacteria PRRs can induce inflammatory response, opsonization and phagocytosis Pattern associated molecular patterns (PAMPs) are molecules such as CpG DNA, cytosolic dsDNA and RNAs made by the host cell
Which of the following steps are part of the processing of antigen by immune cells? Select all that apply. The vesicle containing the antigen fuses with a lysosome. Enzymes in the lysosome digest the antigen into components that bind to MHC markers. The antigen is initially released from the phagocytic cell via exocytosis. The antigen-MHC complex becomes displayed on the cell's interior.
Part of the complement system of defense is opsonization. This process Group of answer choices creates an acidic environment that prevents pathogen attachment coats the pathogen exterior so that it is recognized by the host's phagocytes. causes the pathogen to become trapped in mucus. causes holes to form in the pathogen's cell walls.
phagocytic cells recognize pathogen-associated molecular patterns using their: Group of answer choices phagosomes perforins pyrogens pattern-recognition receptors
Which of these best describes NOD-like receptors? Most are found on the plasma membrane where they recognize external components of pathogens. They are cytosolic proteins activated by intracellular PAMPS and DAMPS. They bind double-stranded nucleic acids of viruses. They are found only on the plasma membranes of T and B lymphocytes. O O O O
Part of the complement system of defense is opsonization. This process coats the pathogen exterior so that it is recognized by the host's phagocytes. creates an acidic environment that prevents pathogen attachment causes holes to form in the pathogen's cell walls. causes the pathogen to become trapped in mucus.
The receptors (TLRS and NLRS) phagocytes use to bind to foreign antigens are collectively called Pattern Recognition Receptors O Pathogen Associated Molecular Patterns O Molecular Associated Pathogen Patterns O Antigen Binding Ligands
Drag each label into the appropriate position to identify what cell type is described by the label. Lead to the synthesis of antibodies Tested to make sure they don't harm one's own tissues Thymosin stimulates them to proliferate Mature from thymic tissues Capable of producing memory cells Involved with IgG and IgM formation in the secondary immune response Arise originally from bone marrow Lymphocytes Can produce lethal hits to infected self-cells Division stimulated by interleukin Involved with antibody- mediated immunity Differentiate into plasma cells when activated T cells B cells Both
Which of the following statements are TRUE about the process of inflammation? (Select all that apply) Inflammation can occur with only the innate immune response involved. Leukocytes or white blood cells are found everywhere in the body to carry out inflammation as needed Growth factor from non-skin cells is responsible for the formation of scar tissue in place of the damaged skin cells The increase of warmed blood to a site of injury comes from the hypothalamus Phagocytes engulf invading microbes and dead white blood cells Phagocytosis is used during inflammation to make sure there is no debris
The classic inflammatory response (heat, swelling, redness, pain) reflects the communication of innate and adaptive defenses. Which of the following is not correct about this response? Group of answer choices Non-cytopathic viruses stimulate the inflammatory response Adjuvants stimulate inflammation and therefore a good antibody response Dendritic cells link the innate and adaptive responses Tumor necrosis factor alpha is a major inducer of inflammation Increased blood flow is one result of inflammation
