The absence of MHC-I at the outside of the Jurkat cell acts as a signal that something is wrong with it. Normally, MHC-I binds to a receptor of the NK and inhibits killing. It's just one of many, many signals but an easy one to use in this scenario.
Ok. Now it's clearer. Thought it was just a homicidal cell with a weird thirst for killing.
