Which two events are required to activate a cytotoxic T cell? There is more than one answer. O Class II MHC molecules present extracellular antigen for binding on a complementary cytotoxic T cell receptor. O IL-4 is released by a TH1 cell to be bound by a cytotoxic T cell. O Class I MHC molecules presents intracellular antigen for binding on a complementary cytotoxic T cell receptor O IL-2 is released by a TH1 cell to be bound by a cytotoxic T cell.
A number of pathogens produce superantigens, which induce a massive production of cytokines by CD4 T cells. Superantigens are different than processed and presented peptide antigens because they do not prime antigen-specific responses. 000 0 do not bind TCRs. bind only to nonclassical MHC molecules. induce loss of surface MHCII.
Naive T cells in CD69-knockout mice might: Group of answer choices Have a defect in recognizing antigen on activated dendritic cells Not be detained in the lymph node to get activated Have a defect in lymph node entry and accumulate in the blood Have a defect in responding to inflammatory cytokines in the lymph node Remain trapped in lymph nodes and fail to recirculate asap please.
Which of the following statements are NOT TRUE about Antigen Presenting Cells (APCs)? (Select all that apply) An APC can become activated from antigen binding as well as MHC binding APCs can carry mutliple MHCs Antigen presenting is due to APC activation Adaptive, innate, and non-immune cells can be APCs APCs travel to the sites of resident macrophages to recruit effector immune cells An APC that binds via their expressed MHC II will be killed
Cytotoxic effector T cells also produce inflammatory cytokines such as IFN-g and TNF-a when their T-cell receptor recognizes peptide:MHC on a target cell. One effect of this cytokine secretion is to enhance the ability of CD8 effector T cells to recognize and kill other infected cells in the nearby vicinity. This enhanced activity is due to: The increased production of perforin and granzymes by CD8 cells The up-regulation of MHC class I protein expression by IFN-g The ability of TNF-a to induce vascular leakage The effect of cytokines on promoting target cell apoptosis The effect of IFN-g to enhance viral replication leading to increased viral antigen presentation
All of the following statements concerning regulatory T cells (Treg) are correct, EXCEPT: The regulatory cytokines produced by regulatory T cells are IL-12 and TGF-B O Thymocytes that recognize self-antigen in the thymus with a certain affinity become natural (central) regulatory T cells O In the periphery T cells that recognize self-antigen in the presence of TGF-B become induced regulatory T cells O A Treg cell can suppress self-reactive lymphocytes that recognize peptides different from that recognized itself provided that the peptides are derived from the same tissue O A Treg cell can suppress self-reactive lymphocytes that recognize peptides different from that recognized by itself provided that the peptides are presented by the same antigen-presenting cell (APC)
Which of the following statements is correct? B cells only recognize antigen presented on MHC class II Dendritic cells are the only cells that can present antigen via both MHC class I and MHC class II CD8 + T cells recognize antigen presented on MHC class I B cells can present antigen via MHC class II for T cells The B cell receptor is a membrane-bound antibody Isotype switch leads to the B cell's antibodies being able to recognize a new antigen The T cell receptor recognizes peptides bound to MHC Main function of CD8 + T cells
The diagram shows a pathogen (in red) that is present in different cellular compartments of each of the cell types shown. In each case, a specific T cell subset will recognize peptides of that pathogen presented on MHC molecules on the surface of the cell, and will execute its effector function. From the list below, match the appropriate T cell effector response to the cell type and location of the pathogen. CD4 T cell killing of target cell CD8 T cell killing of target cell CD4 T cell activation of target cell’s antibody production CD8 T cell activation of target cell’s antibody production CD4 T cell activation of target cell’s ability to kill intracellular pathogen CD8 T cell activation of target cell’s ability to kill intracellular pathogen
Match the type or cause of clonal expansion with the correct situation. Use each choice just one time and make the best match. Clonal expansion of B cells because the cells are infected with EBV Clonal expansion of B-cells because these B-cells have B Cell Receptors that recognize a non-self antigen Clonal expansion of T-cells that have a T Cell Receptor that recognizes EBV antigens A. normal adaptive response by the B cells B. part of pathogenesis of mono C. This allows the adaptive immune system to shut down active EBV infection
