Abstract

CCN1 (CYR61) is a matricellular protein that is highly expressed at sites of inflammation and wound repair. In these contexts, CCN1 can modify the activities of specific cytokines, enabling TNF-α to be cytotoxic without blocking NF-κB activity and enhancing the apoptotic activity of Fas ligand and TRAIL. In this paper, we show that CCN1 supports the adhesion of macrophages through integrin αMβ2 and syndecan-4, activates NFκB-mediated transcription, and induces a proinflammatory genetic program characteristic of classically activated M1 macrophages that participates in Th1 responses. The effects of CCN1 include upregulation of cytokines (TNF-α, IL-1α, IL-1β, IL-6, and IL-12b), chemokines (MIP-1α; MCP-3; growth-related oncogenes 1 and 2; and inflammatory protein 10), and regulators of oxidative stress and complement (inducible NO synthase and C3) and downregulation of specific receptors (TLR4 and IL-10Rβ) and anti-inflammatory factors (TGF-β1). CCN1 regulates this genetic program through at least two distinct mechanisms: an immediate-early response resulting from direct activation of NF-κB by CCN1, leading to the synthesis of cytokines including TNF-α and inflammatory protein 10; and a delayed response resulting from CCN1-induced TNF-α, which acts as an autocrine/paracrine mediator to activate the expression of other cytokines including IL-1β and IL-6. These results identify CCN1 as a novel component of the extracellular matrix that activates proinflammatory genes in macrophages, implicating its role in regulating macrophage function during inflammation.

  • CCN1 supports cell adhesion by binding integrins α6β1 and HSPGs in fibroblasts and smooth muscle cells, αIIbβ3 in activated platelets, αMβ2 in monocytes and macrophages, and αDβ2 in macrophage foam cells.

    “Subsequent studies have shown that CCN1 supports cell adhesion by binding integrins α6β1 and HSPGs in fibroblasts and smooth muscle cells [55,56], αIIbβ3 in activated platelets [57], αMβ2 in monocytes and macrophages [58,59], and αDβ2 in macrophage foam cells [60].”

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.
