Abstract

SHIP-1 is an inositol phosphatase predominantly expressed in hematopoietic cells. Over the ten past years, SHIP-1 has been described as an important regulator of immune functions. Here, we characterize a new inhibitory function for SHIP-1 in NOD2 signaling. NOD2 is a crucial cytoplasmic bacterial sensor that activates proinflammatory and antimicrobial responses upon bacterial invasion. We observed that SHIP-1 decreases NOD2-induced NF-κB activation in macrophages. This negative regulation relies on its interaction with XIAP. Indeed, we observed that XIAP is an essential mediator of the NOD2 signaling pathway that enables proper NF-κB activation in macrophages. Upon NOD2 activation, SHIP-1 C-terminal proline rich domain (PRD) interacts with XIAP, thereby disturbing the interaction between XIAP and RIP2 in order to decrease NF-κB signaling.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • SHIP1 inhibits NF-kB activation and subsequent induction of IL-6, IL-8 and TNF-α expression in human monocytes and mouse bone marrow-derived macrophages independent of its phosphatase activity.

    “SHIP1 was found to inhibit NF-kB activation and the subsequent induction of IL-6, IL-8 and TNF-α expression in human monocytes and mouse bone marrow-derived macrophages independent of its phosphatase activity [130].”

    From Microglial function, INPP5D/SHIP1 signaling, and NLRP3 inflammasome activation: implications for Alzheimer’s disease (2023) · cites this paper as [130]

    In Results, ‘SHIP-1 Downregulates NOD2-induced NF-κB Activation’ (page unavailable), SHIP-1 silencing increases MDP-induced NF-κB activity and IL-6, IL-8 and TNF-α mRNA in the human THP1 monocytic cell line. ‘SHIP-1 PRD Region is Necessary and Sufficient’ reports that inhibition does not require catalytic activity, but tests this in GNV cells. The copy does not show these SHIP-1 findings in mouse bone marrow-derived macrophages; its BMDM passage concerns XIAP deficiency instead. (LLM, conf=0.88)

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.
