Negative regulation of cytokine signaling

Greenhalgh, Christopher J, Hilton, Douglas J·2001·Journal of Leukocyte Biology

Abstract

Cytokines use complex signaling cascades to elicit their biological effects, many of which involve phosphorylation as a mechanism of activation. Rapid and efficient attenuation of cytokine signals is crucial to maintaining regulation of these processes and to preventing toxic side effects. Phosphatases have been shown to be involved in these regulatory processes, but more recent research has seen the discovery of two new families of negative regulators, the suppressor of cytokine signaling (SOCS) and protein inhibitors of signal transducer and activator of transcription (STAT) (PIAS) protein families. SOCS proteins are induced by and inhibit many cytokine-signaling systems in a classic negative-feedback loop, and the generation of transgenic and knockout models has greatly increased our understanding of their physiological functions. PIAS proteins interact with the transcriptional mediators of cytokine action, the STATs, to suppress their DNA-binding activity. These three classes of molecules form what is now emerging as an integrated system for deactivating cytokine signaling at a number of levels, from the receptor to the transcription factor.

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.
