Practice: Influenza is a virus that infects respiratory epithelial cells. If a cell is infected by influenza, in which of the following MHC classes will bits of influenza antigen be presented?

Practice: Mycobacterium tuberculosis causes tuberculosis by living inside of the lungs, though it does not cause intracellular infections.
