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)...

Match each type of immune system cell to its function or description. (Use each description once). Helper T-cell Detects pathogens and releases chemokines as part of the inflammatory response Participates in activation of B-cells if it has receptors for the same antigens Has receptors that are specific to particular antigen structures and releases antibodies as part of the humoral response Releases histamine as part of the inflammatory response Secretes proteins that cause infected cells to undergo apoptosis White blood cell...

Draw a cartoon representing the following caption: Dendritic cells initiate adaptive immune responses. Immature dendritic cells residing in a tissue take up pathogens and their antigens by macropinocytosis and by receptor-mediated endocytosis. They are stimulated by recognition of the presence of pathogens to migrate through the lymphatics to regional lymph nodes, where they arrive as fully mature nonphagocytic dendritic cells that express both antigen and co-stimulatory molecules necessary to activate a naive t cell that recognizes the antigen. Thus the...

Discuss why the function of the dendritic cell can be likened to the famous midnight ride of Paul Revere, together with Charles Dawes and Dr. William Prescott, on the night of 18th of April, 1775. During these excursions, these men warned the Massachusetts countryside that the British were coming. Include in your answer HOW specific aspects of the innate and acquired immune responses, and particularly CD4+ (or helper) T cells, fit into the analogy. http://www.paulreverehouse.org/ride/real.html
