NK cells causing apoptosis of an abnormal host cell, lacking MHC proteins, is an example of the innate immune system's function and does not illustrate an overlap with the adaptive immune system. NK cells can recognize and eliminate cells without the need for prior sensitization, which is a characteristic of innate immunity.
