Chapter 50, Problem 1S
Suppose you take a job in the marketing department of a cosmetics company. Always seeking a competitive advantage, the vice president of marketing has decided to advertise the new skin lotion as having immune-enhancing effects. The lotion is produced from secretions of a plant that releases extremely watery, alkaline fluid. Explain how you will market this product as an immune-enhancer.

Neutralizing antibodies are effective at preventing infection or toxicity mediated by pathogens or their toxic products. In fact, nearly all
vaccines currently in use function by eliciting neutralizing antibodies. One example is the tetanus vaccine, in which neutralizing
antibodies are generated against an inactivated form of the tetanus toxin (the tetanus toxoid). The most important feature of a
neutralizing antibody is
having high affinity for the antigen.
being efficient at activating the complement cascade.
having a high degree of multivalency, such as being a pentamer or hexamer of immunoglobulin monomers.
being present at a high concentration in the circulation.

- A friend was recently diagnosed with strep throat. One week after their treatment, his symptoms returned. Your friend tells you, "I must have become immune to the drug the doctor gave me." Discuss the validity of your friend's statement, providing support for or refuting their claim.arrow_forwardVirus infections induce production of interferons that act on infected cells to enhance their recognition by CD8 cytotoxic T cells. To counter these mechanisms, viruses often encode proteins that interfere with antigen processing and presentation. In an experiment, cells infected with Virus X are treated with interferon and compared with uninfected cells treated with interferon. Proteasomes are isolated from the two cell populations and their enzymatic activities are compared. The data in figure below show the amino acid preferences for cleavage of peptides by the two samples of proteasomes. Based on these data, Virus X most likely encodes a protein that interferes with: The expression of MHC class I on the surface of the infected cell The rate at which peptides are produced from intact proteins in the infected cell The transport of peptides from the cytosol to the endoplasmic reticulum in the infected cell The replacement of constitutive proteasome subunits with immunoproteasome…arrow_forwardIn studies of skin grafts, thymectomized mice (their thymus has been removed) are often used.

- Hypothetically, HPV was used to cure cancer where the cancer was recognized to be foreign by our host immune response. So therefore, which of the following best illustrates how HPV was used to cure cancer?a. The HPV induced a type IV hypersensitivity immune responseb.

Allergens differ from antigens because a. Allergens produce an abnormally large immune response to what is an otherwise harmless particle. b. Allergens do not involve the leucocytes, they simple stimulate the inflammatory response. c. Allergens are only active seasonally and are generally harmless to the body. d. Allergens are primarily plant derived while antigens are bacterial or viral in nature.arrow_forward
