Natural killer cell biology

This is the authors' abstract. We don't add key points for this paper.

Innate lymphocytes can acquire phenotypes and functions determined by an organ or tissue, or by a \ niche within these microenvironments. On the other hand, they can exhibit transient phenotypes and functions—with different amounts or densities of the same receptors. Natural killer cells, as innate lymphocytes, can also have different functions or phenotypes and are primarily tissue-resident lymphocytes.
