Abstract

Exposure of rodents to perfluorooctane sulfonate (PFOS) induces pronounced hepatomegaly associated with significant alterations in hepatic histophysiology and immune status. The present investigation was designed to evaluate the effects of this perfluorochemical on immune-mediated liver damage. Accordingly, the influence of both sub-acute (10 days), moderate-dose (0.004%, w/w=6±1.3 mg/kg body weight/day) or short-term (28 days), low-dose (0.0001%, w/w=144±4 μg/kg body weight/day) dietary pretreatment with PFOS on the development of concanavalin A (Con A)-induced liver damage in mice was examined. With either regimen of exposure, PFOS exacerbated the acute liver damage caused by Con A, i.e., elevated serum levels of transaminases and led to more pronounced damage of hepatic tissue. This exacerbation was associated with either reduced (moderate dose) or unaltered (low dose) hepatic levels of the pro-inflammatory cytokines tumor necrosis factor alpha (TNF-α) and interferon gamma (IFN-γ). Moreover, hepatic DNA fragmentation was enhanced, particularly following short-term exposure to a low-dose. Our findings suggest that exposure to PFOS may sensitize hepatic parenchymal cells to other insults that activate the hepatic immune system and thereby exacerbate liver damage during acute inflammation.

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.
