- Which of the following best describes superantigens? O Superantigens are a class of antibodies that act as antigens presented by MHCII of antigen- presenting cells to overstimulate almost 30% of the T cells of the immune system, which overexpress proinflammatory cytokines leading to immunopathology that can result in multiple organ failures. O Superantigens are a class of antigens that can overstimulate almost 30% of the T cells of the immune system, which overexpress proinflammatory cytokines leading to immunopathology that can result in multiple organ failures. O Superantigens are a class of antigens that can overstimulate the B cells to produce a large number of non-specific antibodies that attack cells in our body leading to immunopathology and multiple organ failure. O Superantigens are a class of antigens that can overstimulate almost 30% of the B cells of the immune system, which overexpress proinflammatory cytokines leading to immunopathology that can result in multiple organ…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.1)Discuss the differences between humoral and cell mediated immunity in terms of chemicals and cells involved in each process as they tackle pathogens 2) what is clonal selection hypothesis and use the autoimmune response and immunological memory to suggest why the hypothesis may be correct or not

Do you believe that chiropractic could be a successful treatment for natural ailments such as fever, stress, & headaches? Yes No Sometimes Explain your choice above:What are features of adaptive immunity? Select all that apply. Antigen receptors are produced by gene recombination. There is no long-term persistence of immunity. The response time is about a week. Specificity is limited to about 1,000 PAMPS.What are features of adaptive immunity? Select all that apply.

- Describe the term "in-frame" and also the reason that it would be necessary for the generation of diversity in antigen receptors.Why is innate immunity referred to as nonspecific? Group of answer choices because it provides defense against a wide range of pathogens because it is a form of defense that functions in all human body systems because it is a form of defense found in all animal species because it provides a built-in mechanism of defense that does not require "training"In clonal selection, “who” does the selecting? What is being selected?
