There is a second, delayed spike of IgM in the secondary response. Why might this be occurring?Choose one: A. When there is a lot of IgG antibody floating around in the bloodstream, some of the monomers link up into IgM pentamers. B. Some IgM is being made by the plasma cells producing the IgG antibodies. C. New naive B cells have been able to activate and produce a new primary response. D. Some of the plasma cells are switching back to IgM production after producing other isotypes for a while.

You have a patient with abnormally high IgE antibodies. What are two scenarios that might lead to a high level of IgE antibodies? How would you find out which scenario is causing the increase in IgE?
B lymphocytes, the precursors of plasma cells, are triggered to proliferate by the binding of multivalent antigens to receptors on their surfaces. The cell-surface receptors are transmembrane immunoglobulins. Univalent antigens, in contrast, do not activate B cells. (a) What do these findings reveal about the mechanism of B-cell activation? (b) How might antibodies be used to activate B cells?
Which of the following statements best explains why the immune system can continue to make antibodies after treatment with the anti-CD20 antibody rituximab? a. New CD20-positive B cells are reconstituted so quickly that antibody concentration during and after treatment is unaffected. b. Rituximab stimulates B-cell proliferation, so for a short while after its administration there is actually an increase in antibody concentration. c. Rituximab is a mouse monoclonal antibody and therefore its Fc region is unable to bind to the surface d. Plasma cells do not express CD20 on their cell surface, and antibody production by these cells continues unhampered. e. Rituximab stimulates anti-antibody production, leading to its rapid clearance by the body.
Suppose a person recovers normally from viral infections, but then gets the same viral infections over and over again- unlike the rest of us. A. What is probably wrong –B cells, helper T cells and/or cytotoxic T cells? B. Should this person be at a higher risk of cancer than the rest of us? C. Should this person be able to lyse bacterial cells as well as the rest of us? D. Should this person tolerate a graft (from an unreated person) better than you are me?
During the secondary immune response, in the serum you would expect a. to find a greater concentration of IgE compared to IgG b. to find a greater concentration of IgM compared to IgG c. to find a greater concentration of IgG compared to IgM
Explain why each choice (a-d) is correct or incorrect. T cells are differentiated into two groups based on their glycoproteins CD4 or CD8. Which of the following is true of CD4 T cells? a. They become cytotoxic T cells. b. The become antigen presenting cells. c. They become T helper cells. d. They become plasma cells.
Which of these statements about the Fab portion of antibodies is true? a.It binds to antigens. b.Its amino acid sequences are variable. c. It consists of both H and L chains. d. All of these are true.
Which of the following statements is NOT true of a fever?a. Temperature is regulated by chemicals that reset the body's thermostat to a higher setting.b. The higher than normal body temperature impairs the functions of some bacteria.c. The higher than normal body temperature is always harmful.d. The higher temperature impairs leukocytes andantibody production.e. Both c and d. Which of the following statements is NOT true of antibodies?a. They bind to foreign antigens, making them susceptible to being engulfed by phagocytes.b. They serve as specific binding sites on B cells.c. An antibody is usually able to bind to a variety of different types of antigensd. They are composed of two heavy chains and two light chains.
Which of the choices is required to activate a helper T cell, which in turn can stimulate antibody production by B cells? A)An antibody displayed by a major histocompatibility complex protein B)A major histocompatibility complex protein alone C)An antigen displayed by a major histocompatibility complex protein D)An antigen alone
Which of the following are characteristics of FceRI? Choose all that apply. A. They bind very tightly to IgE B. They have the tightest of all Ab-Fc interactions C. They are found on all immune cells D. They only bind the Fc region of an IgE when the Fab portion has bound an Ag 2. TGF-b and IL-3 A. promote basophil maturation and inhibit eosinophils B. promote eosinophil maturation and inhibit basophils C. inhibit both eosinophil and basophil production D. promote both basophil and eosinophil production which of the following is true of an innocuous substance? A. It is foreign B. It is involved in type II hypersensitivity reactions C. It binds to mast cells to cause degranulation D. It is supposed to trigger an immune response
of the choices, which cells stimulate directly B cells to divide and produce antibodies? a. mast cells b. marcophages c. Nk cells d. TH cells
If B cells making high-affinity IgG4 are unable to switch to IgE at a late stage in the germinal center reaction during a helminth infection, then _____. (Select all that apply.) a. a chronic infection will ensue b. IgG4 will activate macrophages to secrete inflammatory cytokines c. a type III hypersensitivity reaction will result d. mast cells, basophils, and eosinophils will not be activated e. a delayed-type hypersensitivity reaction is required to eradicate the infection.
