A hypothetical disorder prevents memory cells from forming. What effect would this have on the immune system? B lymphocytes would be affected, but not T lymphocytes, Vaccinations would no longer be useful, The inflammatory response would no longer be effective, or The adaptive immune response would cease to function, but the innate immune response would continue to function normally.

What does innate mean? How is the innate immune system different from the adaptive immune system? Compare the strategies of innate immunity with strategies of adaptive immunity. Give specific examples. How do vaccines protect us from diseases? Which cells in the immune system become activated after the injection? Your answer should be written as 2 or more paragraphs with a total word count of 400 or more.
The immune system can be split into two major categories, the innate immune system and the adaptive immune system. Compare and contrast these two systems and their response to a bacterial pathogen that entered the body through a cut in the skin. In your answer describe two ways in which the innate immune system protects against this pathogen, as well as two ways that the adaptive immune system protectS against this pathogen. Be sure to name any cells/organs/tissues/structures that may be involved in each of these processes in order to receive full marks. This can be done as a list in point form.
Although the immune system has two arms, it has been said, “No T cells, no immunity.” How is this so?
Rebecca developed measles as a young child. As a teenager, she is re-exposed to the measles virus during an outbreak at her high school. What will most likely prevent Rebecca from experiencing any signs or symptoms of measles? As a result of her childhood exposure, her immune system can perform enhanced inflammatory response. As a result of her childhood exposure, her immune system can perform enhanced phagocytosis of virus-infected host cells. She has memory innate immune cells as a result of her childhood exposure. They would be primed to activate rapidly upon subsequent exposure to the same virus during the secondary immune response. She has memory B cells as a result of her childhood exposure. They would be primed to activate rapidly upon subsequent exposure to the same virus during the secondary immune response.
What occurs in a cell-mediated immune response? Select all that apply. Naive B cells bind to antigen on the surface of a bacterium and become activated. A dendritic cell incorporates digested viral antigen-MHC complexes. Naive cytotoxic T cells bind to antigen on antigen-presenting dendritic cells and become activated. Effector cytotoxic T cells circulate through the body and kill any body cells that display the viral antigen-MHC complexes.
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?
The development of primary and secondary immune responses to an antigen differs 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?
Some strains of the human papilloma virus (HPV) are resistant to interferons. If HPV can inhibit interferon binding to cells, what advantage does this give the virus? Question 2 options: Antiviral proteins will not be synthesized in neighbouring cells. Interferons will be released by non-infected neighbouring cells. Interferons will bind to the virus to neurtralize it. Interferons tell the virus-infected cells to apoptose. The viruses will be warned that a host is coming.
What type(s) of biological molecule(s) are the best at inducing immune responses? What properties make these molecules good antigens? (Remember: the biological molecules are lipids, carbohydrates, proteins, and nucleic acids)
Some individuals with immunodeficiency have mutations in the digesting enzymes of their macrophages. What impact might this have on their immune systems? Question 8 options: The adaptive immune response may no longer be activated. Macrophage will no longer recognize the PAMPs with their TLRs. Macrophages will not release cytokines upon tissue damage. MHC receptors will present antigens on the surface of the macrophages.
