This twо pаrt questiоn аddresses the expected results оf experiments using C57Bl/6 mice (genotype H-2 b/b). These experiments аre based on the study by Zinkernagel, as discussed in class, that used a chromium release assay to measure the killing activity of splenic CTL (effector cells, see figure). The CTL were generated in mice after infection with virus. That same virus was used to infect fibroblasts (target cells) that were loaded with 51Cr. Target cells are then co-incubated with spleen cells from the virus-infected mice. If any of the target cells are killed, 51Cr is released, and the amount of radioactivity in culture supernatant will be proportional to the number of killed cells, thus indicating the level of target cell killing. Part 1: C57Bl/6 mice are infected with virus X. Two weeks later, the killing activity of their spleen cells is measured using a chromium release assay and target cells that were also infected with virus X. You set up three different cultures containing target cells that express different H-2 genotypes as follows: b/b, d/d, b/d. Question 1: Which of the target cells in Part 1 will be killed by the C57Bl/6 killer cells? Part 2: Two weeks before infecting the mice with virus, you lethally irradiate them to destroy all immune cells, and then you inject them with bone marrow taken from other mice so they can remake their immune systems. Once they have recovered, you infect them with virus and proceed with the experiment. Question 2: What genotypes of bone marrow (b/b, d/d, or b/d) will allow your mice to generate killer cells after virus infection?
