Questions
Answer 1 оf the 3 questiоns listed belоw. When you choose 1, 2, or 3, you need to fill out аll pаrts of thаt number: FIRST: PLEASE LIST IN YOUR ANSWER WHICH OPTION YOU HAVE SELECTED. Option 1: Part A: What are the functions of decay accelerating factor (CD55) and protectin (CD59) within the complement system? 2 pts Part B: Some patients develop a subset of Red Blood Cells (RBCs) that lack expression of both CD55 and CD59 and these RBCs undergo spontaneous lysis leading to anemia (low RBC count). Explain why the absence of these 2 proteins causes anemia. 3 pts Part C: Predict whether the absence of DAF on RBCs (with normal levels of CD59 on RBCs) would lead to anemia. Justify your answer. 5 pts Part D: In the patient lacking DAF and CD59 on their RBCs, you need to design a therapy to treat the disease. Choose one molecule within the complement cascade that you propose to block, explain the rationale for your answer, and provide an anticipated outcome of the intervention. 5pts Option 2: Two different babies have recurrent bacterial infections. Clinical and genetic studies uncover that baby A has a loss of function mutation in a gene required for neutrophil phagocytosis and baby B has a loss of function mutation in an adhesion molecule required for neutrophils to cross endothelial barriers. Part A: What would you predict would happen if you exposed the neutrophils from each patient to IL-8 in an in vitro assay? Would the responses differ between the samples? 2 pts Part B: Abscesses are collections of neutrophils within tissue in response to a poorly controlled infection. Do you expect that both patients will develop abscesses during bacterial infections? Why or why not? 3 pts Part C: You expose the neutrophils from each patient to the same strain of bacteria in an in vitro assay and attempt to detect the bacteria inside of the neutrophils. Do you expect to find more bacteria within the neutrophils from baby A or baby B and why? 5 pts Part D: If you expose the bacteria to serum complement prior to mixing them with the neutrophils, how will this affect the numbers of bacteria inside the neutrophils of baby A vs baby B. Why? 5 pts. Option 3: Lipopolysaccharide (LPS) is a pathogen associated molecular pattern (PAMP) that binds to a surface-expressed pattern recognition receptor (PRR), Toll like receptor (TLR) 4. In contrast, DNA (PAMP) within the cell cytosol binds to cGAS (cyclic GMP-AMP synthase). Part A: Why are the locations of these PRRs important for their respective functions? 5 pts Part B: Compare and contrast the consequences of LPS/TLR4 activation and DNA/cGAS ligation on an antigen presenting cell? How does each interaction affect the subsequent inflammatory response in terms of which cytokines/chemokines are released. What other immune cells are recruited to the inflamed site? 5 pts Part C: Compare and contrast the predicted immune deficiency (including types of infections) of a patient with a loss of function mutation in TLR4 versus a patient with a loss of function mutation in cGAS. Provide a rationale for your answer. 5 pts.

Write а well-develоped shоrt essаy оf 3 pаragraphs responding to the following prompt: What does Hamlet’s “To be or not to be” soliloquy reveal about his character and his view of life? Analyze Hamlet’s internal conflict and explain how his thoughts about suffering, uncertainty, and action connect to his struggles throughout the play. This soliloquy can be found in Act 3, Scene 1. Your essay should demonstrate that you understand both the meaning of the soliloquy and what it reveals about Hamlet. Remember your goal is not the summarize the "To be or not to be" speech. Instead, use Hamlet's words as evidence to make an argument about his character, his internal conflict, and his struggle between thinking and taking action. Paragraph 1 should be an introduction paragraph. It should briefly introduce Hamlet and the situation surrounding the soliloquy. It should identify the central conflict Hamlet is experiencing. It also should end with a thesis statement that explains what the soliloquy reveals about Hamlet's character and his view of life. Paragraph 2 should explain the main ideas he considers in his speech. Include at least TWO short quotes from the speech. Explain what the words reveal about Hamlet's fears, uncertainty, or personality. Connect his thoughts about suffering and uncertainty to his difficulty taking action elsewhere in the play. Remember quotes should include citations that look like the following: (Shakespeare 3.1.57). Paragraph 3 should serve as a conclusion. It should begin with a reworded thesis that summarizes your main argument. Explain why the soliloquy is important to understanding Hamlet. Lastly, consider what the speech reveals about the larger conflict between thought and action in the play. This response should be 350 words. Grammar and mechanics will be considered as well when grading.
