Hey, everyone. Let's take a look at this question together which immune cells specifically interact with class one MH C molecules. Is it answer choice. A helper T cells answer choice BB cells, answer choice C cytotoxic T cells or answer choice D natural killer cells. Let's work this problem out together to try to figure out which of the following types of immune cells specifically interact with those class one Mh C molecules. So in order to solve this question, we have to recall what we have learned about the different types of immune cells as well as class one MH C molecules to determine which of the following answer choices is the immune cell that specifically interacts with class one Mh C molecules. And we know that the class one Mh C molecules are found on the surface of the plasma membrane on nearly all nucleated cells. And we also know that naive cytotoxic T cells interact with the class one Mh C molecules. And since the naive cytotoxic T cells are what interact specifically with the one Mh C molecules. Answer choice C cytotoxic T cells is the correct answer. And all other answer choices are incorrect. Since helper T cells, B cells and natural killer cells do not specifically interact with class one MH C molecules. I hope you found this video to be helpful. Thank you and goodbye.
