Question
Chapter 45, Problem 15TYU
Summary Introduction
To determine: What does the occurrence of the similar enzymes (Rag1 and Rag 2) in purple sea urchin that was primarily thought to found only in jawed vertebrates suggests about the evolution of adaptive immune system.
Introduction: Immunity is the process of defense performed by an individual’s body in response to a foreign agent that invades the body. Innate immunity is a kind of immunity that is seen in individuals from birth. All animals possess innate immunity that is their first line of defense against any antigen. Adaptive immunity develops after encountering infectious agents.

Sponges display nonspecific immunity. In an experiment, the cells of two different sponges were mixed and placed within a petri dish. The cells from each sponge sorted and arranged themselves together according to organism. What does this characteristic demonstrate?
A. Sponges have memory T-cells and share a more recent common ancestor with vertebrates than other invertebrates.
B. The experiment provides evidence for the speed of evolution and the use of specific immunity within the organism.
C. Sponges have an ability to recognize their own cells as a characteristic of acquired immunity.
D. Sharing genetic information from cell to cell is possible by means of receptors and protein-lined pits.
A vaccination is developed for a novel viral infection, and the antigen used
corresponds to a short stretch of a protein found on the surface of the virus. In
clinical trials, people who were exposed to the virus a second time had superior
immunity to people who were given the vaccine then exposed to the virus for the
first time. What is the BEST explanation for this difference?
The vaccination promoted the production of all memory B cells whereas natural
infection promoted the proliferation of only those memory B cells specific to the
virus.
The vaccination promoted the production of the correct memory B cells whereas
natural infection did not.
People exposed to the virus were able to make many different antibodies that
bind different antigens on the virus.
Vaccinations promote selection of memory B cells, whereas a natural infection
triggers production of cytotoxic B cells.
For some time there has been evidence that the Bacille Calmette-Guérin (BCG) vaccine provides protection not
only against the target disease (Mycobacterium tuberculosis), but also enhances responses to other infections
(such as Staphylococcus aureus and Candida albicans). Do you think the enhanced response to other
infections, as described, is due to innate responses to the vaccine or adaptive responses? Explain your answer.

- picture 1 shows the directed migration of two immune cell types, neutrophils (red) and macrophages (green) to a laser-induced injury in the ear of a mouse. As you can observe from the video, there are three stages to this process: 1) an initial phase characterized by fast recruitment of neutrophils (red) to the site of injury followed by 2) the slower recruitment of macrophages after which 3) the interaction between both cell types is stabilized. Recruitment to the injury site is mediated by leukotriene B4 (LTB4), a potent immune signaling molecule (Figure 1A). LTB4 binds to BLT1, a G-protein coupled receptor (GPCR), activating various signaling pathways and resulting in immune cell migration to the site of injury (Figure 1B). With this background information and your knowledge of cell and molecular biology, describe in detail in your own words, as many molecular processes as you can identify that must take place for the cell migration process depicted in the video to be achieved.

To measure the cytotoxicity of CD8+ T cells from Mouse A, he isolates CD8+ T cells from Mouse A and co-cultures them with a mixture of HSV-infected spleen cells from Mouse B. A day later, he checks the co-culture, but none of the infected spleen cells from Mouse B have been killed. What could explain this observation? a.Mouse B does not express the invariant chain (Ii) b.Mouse A and Mouse B express different MHC alleles c.Mouse A does not express TLR2/6 d.HSV immunoevasins block MHC-II expressionarrow_forwardResearchers can make monoclonal antibodies by immunizing a mouse with a molecule (or with a microorganism). The resulting antibody-mediated response produces a set of antibodies that recognize different parts of the molecule. The mouse's B cells are then harvested from its spleen and fused with cancerous B cells from a myeloma cell line. The resulting hybrid myeloma ("hybridoma") cells are cloned: Individual cells are grown in tissue culture as separate cell lines. Each cell line produces and secretes antibodies that recognize one part of the immunizing molecule. These antibodies are called monoclonal antibodies, and they can be purified and used for research or other purposes. Monoclonal antibodies are effective for passive immunization, but only in the immediate term. Antibodies produced by one's own immune system can last up to about six months in the bloodstream, but monoclonals delivered in passive immunization often last for less than a week. Why the difference?arrow_forward

- 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_forwardThe adaptive immune system uses multiple strategies to generate diversity in our ability to mount responses to a wide array of infectious microorganisms. These strategies include the generation of diverse repertoires of B-cell and T-cell antigen receptors, as well as polymorphism of MHC genes. The polymorphism of MHC genes differs from the diversity of lymphocyte antigen receptors in that: It involves DNA rearrangements at multiple gene segments in the MHC locus. It requires different enzymes than the RAG1/RAG2 recombinase required for antigen receptor rearrangements. It results in a diverse repertoire of clonally distributed receptors on dendritic cells, rather than on lymphocytes. It creates diversity between individuals in the population rather than within a single individual. It does not contribute to the transplant rejection responses that occur after organ transplantation between unrelated individuals.arrow_forwardThere is no known association between vaccinations and the development of autism -- many studies have looked for a connection without finding one. Despite the research, many parents express concern about vaccinating their children because they are worried about their child developing autism.
