Treating patients with convalescent plasma involves obtaining blood from patients that have already survived the virus and injecting their plasma into patients currently suffering for the disease. How would treating patients with convalescent plasma potentially kill COVID-19? A Increased helper t cell mediated activation в Increased monocyte/macrophage counts Increased albumin binding D None of the answers are correct E Increased B lymphocyte activation F Increased neutrophil counts Increased IgG binding

Put the following steps in order for cell-mediated immunereactions:(a) Differentiated T cells include T helper, delayed hyper-sensitivity, cytotoxic, and memory T cells that all havedifferent immunological functions depending on the an-tigen presented.(b) Antigen-presenting cells (macrophages and dendriticcells) phagocytize pathogens, ingesting and degradingthem into pieces which are transported to the surface ofthe cell.(c) T cells bearing the corresponding receptor for the pre-sented antigen bind to it and become activated only ifthe appropriate MHC is also present.(d) Some pieces of the pathogen’s antigens are processedby inserting them into the antigen-presenting cell’smembrane and are held in place by class II majorhistocompatibility complex (MHCII) proteins.(e) Activated T cells are stimulated to divide and differen-tiate into different types of T cells, including memorycells
An infant appears healthy until about 9 months of age, when he develops severe bacterial infections, one after another. Fortunately, theinfections are treated successfully with antibiotics. When infectedwith the measles and other viral diseases, the infant recovers withoutunusual difficulty. Explain the different immune responses to theseinfections. Why did it take so long for this disorder to become apparent? (Hint: Consider IgG.)
Mobilization of neutrophils to fight infection in tissue is mediated by all except which a. TNF-a production by macrophages b. upregulation of selectins on blood vessel endothelium c. interferon response d. generation of a CXCL8 gradient e. extravasation across endothelium f. proteolysis of basement membrane of blood vessels.
Some Type-II immunopathology mediated autoimmune diseases have manifestations inmultiple different organs. Discuss how antibodies to one single antigen can cause damage inmultiple sites throughout the body. Things you might discuss include, but are not limited towhere the antigen could be expressed, how antibodies are made, how they bind antigen,where they circulate, the ratios of antigen to antibody, mechanisms of the immune systemthat result in cellular/tissue damage, or how immune system components can affect otherorgans. You might also comment on what makes one antigen an attractive target rather thananother. Please do NOT comment on all the things listed above, they are just to get youthinking. If you are having trouble getting started, it might help to think about a specificdisease which affects multiple organs.

A 67‐year‐old man with rheumatoid arthritis presents with neutropenia. The blood count shows a mild lymphocytosis with an increased number of cells which express CD3, CD16 and CD57. T cell gene rearrangement study shows a clonal band. Which ONE of the following is the diagnosis in this case? Select one: A.Mycosis fungoides B.Infectious mononucleosis C.Large granular lymphocyte leukaemia D.Chronic lymphocytic leukaemia
Helper T cells can be activated by macrophages(which engulf everything indiscriminately) or by B cells (which only engulf antigens that stick to their receptors). A. What properties so macrophages and B cells have ibn common that allows them both to activate T cells? B. It has been suggested that macrophages probably do most to fhte T cell activating in the primary response but B cells do most of it in the secondary response. Why does this make sense?
