To establish a persistent infection, viruses evade many aspects of innate and adaptive immunity. Examples of viral immune evasion strategies are described below. For each strategy, please state whether virally-infected cells (i.e. the ‘target cell’) would be killed by: i) virus-specific CTLs and/or ii) NK cells, and explain why target cell killing by these lymphocytes would or would not occur, for these responses do not consider ADCC reactions. Write 1-2 sentences each part, using the format below (you just need to write A, B, and C and i and ii. A) HIV often harbors mutations in the sole viral epitope presented by MHC class I, resulting in loss of viral peptide binding to the MHC I. i) Virus-specific CTLs: ii) NK cells: B) Human cytomegalovirus (HCMV) encodes a protein called US3 that binds to MHC Class I molecules and retains them in the ER, so that they are never presented on the cell surface. i) Virus-specific CTLs: ii) NK cells: C) Poxviruses encode a protein called crmA, which can inhibit caspases 3 and 8. i) Virus-specific CTLs: ii) NK cells:

A reseаrcher wishes tо see whether there is а relаtiоnship between the calоric contents and the sodium contents (in milligrams) of 10 beef hot dogs. She selects five brands of hot dogs, determined the caloric contents and the sodium contents (in milligrams) of each brand. The data is listed in the table below. Caloric Content, x Sodium content (mg) 150 380 170 470 120 340 120 360 90 300 Compute the value of the correlation coefficient (you may use your calculator). Round the value to 4 decimal places. Test the correlation coefficient for significance. Be sure to include your null and alternative hypotheses (including symbols - use the insert equation editor to do so), If using the t-test: your t-critical value, your calculated t-test statistic, decision rule, decision, and conclusion. The level of significance alpha, α = 0.05. If testing using table I, the statistically significant/critical value correlation coefficient, your calculated correlation coefficient, decision rule, decision, and conclusion. The level of significance alpha, α = 0.05. If applicable, find & interpret the coefficient of determination, R2. If applicable, find the linear regression equation. If not applicable, explain why it is not. If applicable, find the predicted sodium content if the caloric content is 160 calories. If not applicable, explain why it is not. If applicable, find the predicted sodium content if the caloric content is 200 calories. If not applicable, explain why it is not.
