Question
Chapter 45, Problem 12TYK
Summary Introduction
To review:
The mechanism that foreign invaders use to trigger the immune responses. The mutated virus with surface protein altered pose a monitoring problem for memory cells.
Introduction:
The foreign invaders (antigens) when enters the body, the immune system of the body recognizes them as nonself and destroy them by representing them to immune cells. The interaction of foreign invaders and immune cells cause the immune cell activation. The immune cells now produce some chemicals and produce antibody as an immune response.

Given what you now know about how foreign invaders trigger immune responses, explain why mutated forms of viruses, which have altered surface proteins, pose a monitoring problem for a person’s memory cells.
Refer to figures and compare and contrast how both viruses use surface receptors to evade an immune reaction and neutralizingantibodies.

- with HIV, explain the mechanism of intracellular infection and the role of reverse transcriptase. What would you explain about the process? What is the significance of the CD4+ count? ( Discuss the meaning of various ranges of CD4 counts.) List 5 opportunistic infections AND describe data to suggest whether or not a patient has such an infection.arrow_forwardTo put an end to the COVID-19 pandemic, vaccines were developed against the virus and people eligible to receive these are encouraged to get vaccinated. How do these vaccines work? * The vaccine will not cause the disease, but will help develop the body’s first line of defense. The vaccine mimics the virus that causes the disease and triggers the creation of antibodies. No answer The presence of the virus in the vaccine will improve the innate immune response of the body. The vaccine causes a mild infection that will trigger the production of antibodies against the virus.arrow_forwardConsidering that each virus must bind to a specific cell surface receptor for attachment, explain how you would create a drug that prevents viral attachment.arrow_forward
- Consider the separate stages of an animal virus life cycle. Assemble a short list of structures and processes that are unique to the virus and would make good drug targets for an antiviral agent. Explain your rationale for each choice.arrow_forwardDescribe a drug therapy that has been used for patients infected with SARS COV2. What does it target/disrupt - a part of the virus itself, a viral process, the host immune response?arrow_forwardA number of vaccines against the SARS-CoV-2 virus (which causes COVID) are currently in use. Based on what you learned about the immune system and vaccines, this vaccine should provide immunity against this virus because: a Vaccines bind to the variable region of immunoglobulins, and prevent the antibody-antigen interactions required for the virus to be released from cells. b Vaccines elicit a primary immune response and resulting memory cells specific to the viral antigens can persist in the body c Vaccines block clonal expansion of helper T cells which are required for the virus to infect cells d Vaccines block the production of cytokines e Vaccines induce cytotoxic T cells to produce antibodies specific to antigens on the virusarrow_forward
- Killer T-cells help protect us from viral infections. Explain the mechanism of their action.arrow_forwardViruses can easily mutate exchange genetic material, mechanisms referred to as antigenic drift and antigenic shift. These changes allow the virus to evade the immune system defenses. Match each term with the correct definition Antigenic drift [ Choose ] [Choose ] Different strains of a virus or strain of different viruses, combine and form a new strain that now has a mixture of the surface antigens Antigenic shift The virus changes genetically by accumulating mutations within the genes that code for antibody-binding sitesarrow_forwardYou work for a large biotechnology company that is studying viruses, vaccines, and small molecule inhibitors. You are asked to give an overview of cell signaling as it relates to the coronavirus and young adults. a) Describe cell signaling pathways (e.g., at least 3) that are likely manipulated during a coronavirus infection. In your description, include how the pathways are involved in antagonizing the host antiviral response.arrow_forward
- Imagine a new viral infection has emerged in the southwestern U.S. The virus has distinct surface properties such that prior infections with other viruses is not providing immunity against this virus and it starts to spread rapidly. Diagram and/or describe the major steps of immune response to infection by this virus. Include both the innate and adaptive immune responses. How do antibodies help block viral infection? Once the virus enters a cell it is no longer accessible to antibodies or immune cells. What type of T cells are most important for this stage of infection? How do these T cells recognize infected cells and stop the infection?arrow_forwardBriefly list three mechanisms by which monoclonal antibodies that bind to viruses or virally infected cells, such as anti-Spike protein antibodies, cause reduction of viral infection and spreadarrow_forwardConsider the events that occur in HIV infection. I. HIV undergoes molecular self assembly.II. The protein gp120 binds to CD4.III. The HIV genome is incorporated into the host cell genome.IV. Reverse transcriptase is activated.V.
