Name the organism that can infect B cells, T cells, Dendritic cells and macrophages
M. tuberculosis can not only infect and subvert macrophages, but also dendritic cells, by similar mechanisms. However, the consequences for immunity are distinct. Using your immunological knowledge, predict the consequences on immunity caused by MTb suppression of phagosome killing in dendritic cells:
Skin Intestine Dendritic Cells Basophils Mouth Lungs Stomach B Cells Macrophages Neutrophils Eosinophils T Helper Cells Cytotoxic T Cells Natural Killer Cells Interferons Complement Antibodies Cytokines Mast Cells Microbiome.: Adaptive immune system components; For each one of the components, indicate: What activates the component and What functions does this component play in the immune defense of the body
Which is a type of presentation complex found only on macrophages, dendritic cells, and B cells? a. Epitope b. MHC I c. MGC II
Explain the role of innate immune cells such as macrophages and dendritic cells in adaptive immunity in regards to cancer.
Which of the following are true of phagocytosis Group of answer choices dendritic cells and macrophages are examples of phagocytes all of these are true opsonization increases phagocytosis some bacterial pathogens can evade phagocytosis using a capsule some bacterial pathogens can escape from the phagolysosome or prevent it from forming
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)
1. The primary host cell targets of Dengue Virus (DENV) are macrophages and dendritic cells. Discuss how Fc? receptors may contribute to the proliferation of infection in host cells, and state what type of hypersensitivity reaction this would represent.
Which of the following cell types does NOT engulf and degrade pathogens? a. macrophages b. B cells c. dendritic cells d. neutrophils e. T cells
Q1: Describe the ways in which follicular dendritic cells (FDCs) are similar to subcapsular sinus macrophages. Q2: Explain why expression of CD40 ligand by TFH cells is important in the boundary area of primary follicles in secondary lymphoid tissue as it relates to the targeted delivery of secreted cytokines to the B-cell surface. Q3: (i) .What is the main effector function of IgM antibody? (ii) Why is IgM efficient at (i) preventing blood-borne infections and (ii) fixing complement, but (iii)...
