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.

- To 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_forwardConsider 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_forward
- A 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_forwardHIV can be treated with therapy, but there is a growing in the level of innate immune activation despite control of T cells and a negligible viral load. Explain why you think this may happen?arrow_forwardKiller T-cells help protect us from viral infections. Explain the mechanism of their action.arrow_forward
- Viruses 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_forwardIn terms of a virus, how could injecting an mRNA sequence trigger an immune response. be sure to also explain how antibodies, antigens, t cells, b cells, and immune memory work within this situation.arrow_forwardImagine 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_forward
- Briefly 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_forwardWhich of the following is NOT a mechanism used by the immune system to fight multicellular parasites? Select one: a. Antibodies coating the pathogen surface bind to FcRs on mast cells, causing release of granule contents onto surface, and damage the parasite. b. Crosslinking of antibody binding to FceRI on eosinophils cells triggers release of granules, causing smooth muscle contractions. Muscle contractions in the mucosal tracts causes sneezing, coughing, vomiting or diarrhea, dislodging the parasite. d. The parasite is killed and broken down extracellularly, and then phagocytosed by macrophages. C.arrow_forwardAntibodies play a critical role in the prevention of infection by the specific viruses the antibody is designed to detect. Which immune system cell produces antibodies? Indicate four ways that antibodies can disrupt the ability of a virus to infect a cell. PLEASE ANSWER ALL PARTS TO THIS QUESTIONarrow_forward
