irradiated tumor cells Tumor cells from a mouse were first killed by irradiation and then injected into a mouse of the same strain to immunize the mouse. immunize mouse with irradiated tumor cells If live cells from the same tumor were later injected into the immunized mouse, no tumor formed (left experiment). Which of the following is a CORRECT interpretation for this result? a. The cancer stem cells survived the irradiation. b. The live tumor cells were killed by immune rejection. C. The mouse recognizes the live tumor cells as self cells. d. The mouse develops antibodies against the tumor cells. inject viable cells of the same tumor inject viable cells from a second, independently induced tumor The experiment on the right used live cells from another, but same type of, tumor to inject the same mouse. Surprisingly, tumor formed in the mouse. host response host response rejects tumor permits proliferation Which of the following is an INCORRECT interpretation for this result? cells and of cells and prevents tumor growth tumor formation a. The mouse has no antibodies against the live tumor cells Figure 15.16 The Biology of Cancer | Garland Science 2014 b. The live tumor cells suppress the immune function of the mouse. C. The live tumor cells used in this experiment are molecularly different from those in the left experiment. d. The live tumor cells are recognized as self cells.

Which of the following is NOT an immunoevasion strategy used by cancer cells? a. Release of TCE-R b. Suppression of MIHIC class I expression. c. Reduce the expression of growth factors. d. Generation of weakly antigenic variants A)
