Which of the following immunological activities does NOT occur at sites of infection during an immune response? phagocytosis by macrophages, neutrophils, and dendritic cells the killing of infected cells by effector T cells opsonization of bacteria Activation of T cells by antigen-presenting cells

6) Your mice have been infected with a bacteria. Describe why the absence of the following immune cells will alter the normal function of immune response and host susceptibility to this infection. (8 pts) A. Neutrophils? B. Dendritic cells?

Describe the process of T cell activation by tissue-resident Dendritic cells following infection, focusing on the maturation process of the DCs and how this process impacts the DC function during this process (Hint: Immature DCs and Mature DCs). Why does this process make DCs the primary antigen presenting cells for naive T cells compared to macrophages and B cells? (10 points)

Which of the following activates cytotoxic T cells as part of the acquired immune response against virus infected cells? -Virus infected cell -Virus infected cell that presents a viral antigen on its surface -A virale infected cell that presents both a viral antigen and a MHC class 1 protein -A virale infected cell that presents both a viral antigen and a MHC class II protein Which of the following is a role of macrophages in a secondary lymph organ in...

Immunology (elaborate explanations are not necessary 3-4 sentences are suffice) State timing, steps and cells involved in the innate immune response to bacterial antigens and contrast this with adaptive immune responses to the same antigen. Explain how macrophages recognize bacteria and the host mechanisms that lead to recruitment of cells to sites of infection. Explain how inflammation is triggered, the changes in cells at sites of infection that occur and how this relates targeting of both phagocytes and adaptive immune...

Question 1: B cells secrete these types of immunoglobulin antibodies. Choose all correct. 1. IgD 2. IgL 3. IgG 4. IgM 5. IgA 6. IgE True or False Questions 2. T cells expressing CD8 protein on their surface are called cytotoxic T cells and function in the killing the infected APC cell. 3. Antigen presentation on the cell surface is a way to tell the immune system that they are infected and the presented molecule tells T cells what they...

Question 11 3 pts Why is expressing multiple MHC molecules beneficial to a single individual? This has no impact on the person's immune response to a specific antigen This ensures an effective immune response to a specific antigen This decreases the likelihood of an effective immune response to a specific antigen This increases the likelihood of an effective immune response to a specific antigen Question 12 3 pts Effector B cells include: Antibody secreting cells Antibody-secreting cells and T-cells Mature...

multiple choice question: microbiology A) What contents are released by NK cells into infected cells to start the process of apoptosis? Antibodies. Granzymes. Viruses. T cell receptors. B) The T cell receptor of CD4 T cell recognizes: Free peptides. MHC I / peptide complex. MHC II / peptide complex. Both a and c. C) Th1 is a subset of CD4 T cell that are good for clearing: Viral infection. Extracellular bacterial infection. Intracellular bacterial infection. All of the above. D)...
