Suggest some reasons that there is so much redundancy of action andthere are so many interacting aspects of immune responses.
Compare and contrast innate and adaptive immunity. Include three similarities in terms of cell and/or cytokine actions and a discussion of the three hallmark differences (used to define each immune response).
Describe the relative importance of innate immunitycompared to adaptive immunity
List the cell types involved in innate immunity and the functions ofeach.
a. Describe what could be summarized as the three Rs of immunity:recognize, react, remember.b. Why would it be necessary for the T cells to bind both antigen andself (MHC) receptors?
Adaptive immunity can be divided into four distinct classifications, describe each: natural active immunity, natural passive immunity, artificial passive immunity, and artificial active immunity Describe the functions of each of the three classes of T cells.
Some primitive organisms, such as invertebrates, have no lymphocytes and thus lack an adaptive immune system, but they have somecomponents of an innate immune system, including phagocytes andcertain protective proteins. What are some general features of innateimmunity that make it very valuable to organisms lacking more specific antibody- and cell-mediated responses? What are some disadvantages to having only an innate immune system?
Explain how innate, antibody-mediated, and cellmediated immunity can function together to eliminatean antigen.
Name five cell types involved in innate immunity and themajor functions of each.
The development of primary and secondary immune responses to an antigen differ significantly. The primary response may take a week or more to develop fully and establish memory. The secondary response is rapid and relies on the activation of clones of memory cells. Would it not be better if clones of reactive cells were maintained regardless of prior exposure? In this way, the body could always respond rapidly to any antigen exposure. Would there be any disadvantages to this approach? Why?
Select all of the following statetments that apply to immunological memory: A. A small population of plasma cells secrete pathogen-specific antibody long after pathogen clearance from the body. B. Memory T cells and memory B cells originate in secondary lymphoid tissue through colonal expansion. C. Memory T cells are produced during secondary immune responses, but not during primary immune responses. D. During a primary immune response, effector B cells outnumber memory cells. E. protective immunity persists for the same period regardless of the type of pathogen F. Memory B cells generated in secondary immune responses are more effective than memory B cells made in primary immune responses because of affinity maturation
One theory for long-lasting immunity assumes that humans arecontinually exposed to the disease-causing agent. Explain how thisexposure can produce lifelong immunity
