Chapter 17, Problem 31QP
Summary Introduction
To determine: The way in which the immune system would deal with a viral infection in case of nonactivation of T cells.
Introduction: The primary function of the immune system is to protect the body from foreign substances. Cellular immunity (T-cells and cytokines) and antibody-mediated immunity (B-cells and antibodies) are two major immunities found in an individual.

Many cells in the human body have proteins on the surface that are able to interact with the receptors of helper T cells. Explain the mechanisms and why it is that such an interaction or signal does not usually result in an autoimmune reaction?
Innate lymphoid cells reside primarily in tissues such as the lungs, the lining of the gastrointestinal tract, and the skin, because these sites represent the major routes of entry of pathogens into the body.
Several different subsets of innate lymphoid cells exist, and each is specialized to respond to a category of pathogen (e.g., viruses, extracellular bacteria, helminthic parasites, etc).
a) True
b) False
Both antibodies and particular complement proteins, such as c3b, are capable of
aiding phagocytes in attaching to bacteria. What term best describes these?
O
1) opsonins
O 2) haptens
O 3)
pyogens
O 4) perforins

- The current view in the field of immunology is that dendritic cells are the primary antigen-presenting cells for stimulating naive T cells. One piece of evidence supporting this conclusion is the observation that IRF8-deficient individuals, which retain their tissue-resident macrophages, are susceptible to a range of severe opportunistic infections caused by intracellular bacteria, viruses, and fungi. Explain the reasoning behind this argument.arrow_forwardName two cytokines that are thought to be involved in the inflammatory response to viruses (cite your source). Describe a component of the innate immune response to viral infection (name it and explain how it works. Be sure you are talking about something that protects you from viruses.)arrow_forwardWhich of the following statements is NOT correct? Group of answer choices -Natural killer cells are cytolytic lymphocytes that mediate ADCC -Neutrophils carry out phagocytosis of C3b-tagged particles -Macrophages carry out phagocytosis of C3b-tagged particles -Mast cells produce granules containing the cytotoxin perforin -B lymphocytes express a receptor for complement proteinsarrow_forward
- HIV predominantly infects T-helper cells, cells that are responsible for coordinating B- and T-cell activity. Based on this information, explain why HIV-infected individuals are at a very high risk for developing microbial infections. List the causative agent (virus) and discuss its properties. Name and briefly discuss 3 diseases that AIDS patients are more likely to contract.(Terminology to use: opportunistic pathogens, T and B cell purposes, CD4 cells, retrovirus, reverse transcription)arrow_forwardwith 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_forwardThe transplantation of organs from one person to another was impossible until the discovery of immunosuppressive drugs. Now, with the use of drugs such as cyclosporine, organs can be transplanted without rejection. Transplant patients must take immunosuppressive drugs for the remainder of their lives. What are the potential risks associated with long-term use of immunosuppressive drugs?arrow_forward
- Generally, polysaccharides are not good antigens, because B cells that recognize them cannot get T-cell help. But for some pathogens, such as Streptococcus pneumoniae opsonization by antibodies that bind the thick polysaccharide "capsule" layer surrounding the bacteria is the major mechanism of clearing the infection. As expected, a pure polysaccharide vaccine is not terribly effective, but much better immunity is achieved by vaccinating with a polysaccharide covalently linked "conjugated" to an unrelated protein. Explain how this conjugate vaccine allows B cells capable of making anti-polysaccharide antibodies.arrow_forwardAccording to the clonal selection theory, all immunoglobulin molecules in an individual B cell have the same antigenic specificity. Explain why the presence of IgM and IgD on the same B cell does not violate the nonspecificity implied by clonal selection.arrow_forwardEmil has fallen and scratched a wound on his knee. After a while, the knee swells and aches at the same time as it was pushing out of the wound. One week later, the wound has healed and the swelling is gone.

How can this medicine help prevent allergies? What negative side effects can this drug have?b) Compare the defense mechanisms that occur in response to bacterial and viral pneumonia.arrow_forward1) According to the video, what is another name for the innate immune sys and what does this system do? 2) According to the video, what causes inflammation and what cells cause it? 3) According to the video, what happens to neutrophils after they consume a pathogen? 4) According to the video, natural killer cells; what do they do? 5) The adaptive/acquired immune system can tell the difference between types of pathogens: true or false? 6) According to the video, helper t- function: 7) According to the video, cytotoxic t cells function: 8) According to the video, memory cells function:arrow_forward
