You note a population of T cells that contain primarily high-affinity IL-2R on their cell surfaces. Based on that observation, what can you predict about the activation state of the cells? Question 6 options: They have not been exposed to antigen. T cells do not express IL-2R, so we cannot determine their activation state using these data. This cell population has been exposed to IL-2 and is active. They have been exposed to antigen but not IL-2. None of the answers are correct.
