Answer 1 оf the 3 questiоns listed belоw. When you choose 4, 5, or 6, you need to fill out аll pаrts of thаt number: FIRST: PLEASE LIST IN YOUR ANSWER WHICH OPTION YOU HAVE SELECTED. Option 4: DiGeorge’s syndrome is a disease in which babies are born without a thymus. Part A: What is the expected immune abnormality of patients that lack a thymus? Will this affect innate and or adaptive immune responses and which cells? Will these patients be able to generate antibodies? Will the patients be able to respond effectively to bacteria and/or viruses? Rationalize your answer. 7 pts Part B: Compare the findings from the DiGeorge syndrome patient to a patient that lacks RAG1. Will RAG1 deficiency result in abnormalities in innate and or adaptive immunity and which cells will be affected? Will the cells affected be the same or different from the DiGeorge syndrome? Will the patient be able to respond to bacteria and or viruses? Rationalize your answer. 8 pts Option 5: Mature B cells can undergo class switch and recombination affinity maturation. Part A: Explain how these processes differ, including when and where they occur. 5 pts Part B: What enzyme(s) is crucial for these events to occur and explain its molecular function. 2 pts Part C: What is the function of B cell expressed CD40? 3 pts Part D: What is the anticipated effect of a loss of function mutation in CD40 on a patient’s ability to make antibody? How will this affect the patient’s ability to mount an effective immune response to pathogenic bacteria vs viruses? Explain your answer. 5 pts Option 6: Naïve CD4+ T cells can differentiate into various effector subtypes with distinct functions including Th1 cell. Th2 cells, Th17 cells and regulatory T cells. Certain pathogens can survive intracellularly: mycobacterium tuberculosis and leishmania, as examples, are engulfed by macrophages but initially survive the harsh environment of the phagolysosomes. Potent CD4+ T cell responses are needed to control the infections. Part A: Which of the above listed types of effector CD4+ T cells will be most effective at clearing this infection? Explain your answer. 3 pts Part B: What are the mechanisms that these CD4+ T cells use to promote killing of the pathogen within the phagolysome? List one cytokine produced by the T cells (identified in part A) and explain its functions. 4 pts Part C: Using an animal model of leishmania infection you test the effects of administering IL-12 or IL-4 on the ability of the animal to clear the infection. What is the predicted outcome of treating the animal with IL-12? Explain your answer. 4 pts Part D: Using the same model, what is the predicted outcome of treating the animal with IL-4? Explain your answer. 4 pts.
