Abstract

Although NK cells are well known for their cytotoxic functions, they also produce an array of immunoregulatory cytokines and chemokines. During an immune response, NK cells are exposed to complex combinations of cytokines that influence their differentiation and function. In this study, we have examined the phenotypic and functional consequences of exposing mouse NK cells to IL-4, IL-12, IL-15, IL-18, and IL-21 and found that although all factors induced signs of maturation, characterized by decreased proliferation and IFN-γ secretion, distinct combinations induced unique cytokine secretion profiles. In contrast, the immunosuppressive factors IL-10 and TGF-β had little direct effect on NK cell effector functions. Sustained IL-18 signals resulted in IL-13 and GM-CSF production, whereas IL-12 and IL-21 induced IL-10 and TNF-α. Surprisingly, with the exception of IL-21, all cytokines suppressed cytotoxic function of NK cells at the expense of endogenous cytokine production suggesting that “helper-type” NK cells were generated. The cytokine signals also profoundly altered the cell surface phenotype of the NK cells—a striking example being the downregulation of the activating receptor NKG2D by IL-4 that resulted in decreased NKG2D-dependent killing. IL-4 exposure also modulated NKG2D expression in vivo suggesting it is functionally important during immune responses. This study highlights the plasticity of NK cell differentiation and suggests that the relative abundance of cytokines at sites of inflammation will lead to diverse outcomes in terms of NK cell phenotype and interaction with the immune system.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
