Step by step
Solved in 3 steps
- Attenuated agents may induce immunity after a single dose may cause disease in immunocompromised (sick) individuals multiply in the body may revert or mutate to disease-causing strains all of the aboveThe Adaptive Immune Response Is a Specific Defense Against Infection Describe the genetic basis of antibody diversity.Some Pattern Recognition Receptors (PRRs) recognize nucleic acids, like RNA or DNA. Since our own cells contain human RNA and DNA, the activation of innate immune pathways by these PRRs must rely on additional criteria to discriminate self from nonself. Additional criteria include everything EXCEPT: The subcellular location of the RNA The presence of adenosine residues in viral RNA The methylation state of the DNA Unique structures found on viral RNA The subcellular location of the DNA
- How do vaccines work in the body? How do they utilize adaptive immune response? Also, kindly give an example (i.e., COVID vaccines).Which of the following best describes an attenuated whole-agent vaccine? Uses antigenic fragments of a microbe to stimulate immunity Uses living but weakened microbes to stimulate immunity Uses killed microbes to stimulate immunity Combination of antigens to enhance immune response Inactivated toxin (toxoid) that induces immunity against microbial toxinSuperinfection immunity refers to: O the inability of a temperate phage to infect any bacterial lysogen O the inability of a temperate phage to undergo the lytic life cycle after existing as a prophage the inability of a lytic phage to infect any bacterial lysogen O a bacterial lysogen being unable to be infected by similar, closely related phages
- If the researchers carry out a PCR for this gene from the CD8+ T cells, what result would you expect?Explain.Labs that do a lot of Western blots often have hundreds of primary bodies but only two or three secondary antibodies. Why? I understand that secondary antibody aids in the detection, sorting or purification of target antigens by binding to the primary antibody which directly binds to the target antigen. However, I don't undrstand why there are only two or three secondary antibodies available in the laboratory. Glad if the expert would advise.What type of cell production is stimulated by the Pfizer and Moderna COVID vaccines (select all that apply)? | Mast cells B cells T cells | Stem cells
- How could cyclosporine be used to treat autoimmune disease? be sure to explain you're reasoningWhich 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…The process where antibody will cause microbes to be connected together so they can no longer cause infection is called: excision inactivation coarctation agglutination
