Abstract

Besides their growth-inhibiting and differentiation-inducing properties, retinoids have been shown to exert immunomodulatory and anti-inflammatory functions by mechanisms that are not well understood. Tumor necrosis factor-alpha (TNF), a cytokine produced by mononuclear phagocytes, has been shown to be an important mediator of endotoxin-induced septic shock, cachexia, bone resorption, and inflammation. Nitric oxide may also have a role in septic shock, hypotension, and vasodilatation. In this study, we examined the effects of retinoids on the production of TNF and nitric oxide by murine peritoneal macrophages. Of the various retinoids studied, all-trans-retinoic acid (RA) was most potent; it almost completely inhibited the production of TNF by macrophages activated with endotoxin and interferon-gamma. The inhibitory effect was dependent on the dose and duration of RA exposure to macrophages. RA also blocked phorbol ester-induced TNF production in a macrophage cell line (RAW 264.7). Besides TNF, the retinoid suppressed the production of nitric oxide from activated peritoneal macrophages. The importance of these results in relation to controlling various harmful effects of cytokines released by activated macrophages is discussed.

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.
