Abstract

The liver, a unique tolerogenic organ, is regarded as the site to trap and destroy aging erythrocytes and activated T cells. However, to date, the mechanisms for why the liver is tolerogenic and whether liver Kupffer cells (KC) are critical phagocytes for apoptotic cells (AC) contributing to the liver immunosuppression remain unclear. Here we report that KC is the main phagocyte for AC in the liver. Contact of AC inhibits proinflammatory cytokine but enhances anti-inflammatory cytokine production of KC in response to lipopolysaccharide (LPS) stimulation. Membrane-bound transforming growth factor (TGF)-β on AC is responsible for the increased production of interleukin (IL)-10 in KC through extracellular signal-regulated kinase (ERK) activation via the Smad3 pathway. Importantly, KC-derived IL-10 is critical for AC infusion-mediated protection of endotoxin-induced fulminant hepatitis through suppression of tumor necrosis factor (TNF)-α and nitric oxide (NO) production from KC and consequently attenuation of KC-mediated cytolysis of hepatocytes. Conclusion: AC can be preferentially phagocytosed by KC in the liver, leading to attenuation of fulminant hepatitis through IL-10-mediated suppression of KC-derived inflammatory TNF-α and NO production. These findings demonstrate that priming of KC by AC may contribute to maintain liver immunosuppression, providing a new mechanistic explanation for how immune homeostasis is maintained in the liver.

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.
