Abstract

Depression is associated with somatic immune changes, and neuroinflammation is now recognized as hallmark for depressive disorders. N-3 (or omega-3) polyunsaturated fatty acids (PUFAs) are well known to suppress neuroinflammation, reduce oxidative stress, and protect neuron from injury. We pretreated animals with fish oil and induced acute depression-like behaviors with systemic lipopolysaccharide (LPS) injection. The levels of cytokines and stress hormones were determined from plasma and different brain areas. The results showed that fish oil treatment prevent LPS-induce depressive behavior by suppression of neuroinflammation. LPS induced acute neuroinflammation in different brain regions, which were prevented in fish oil fed mice. However, neither LPS administration nor fish oil treatment has strong effect on stress hormone secretion in the hypothalamus and adrenal. Fish oil might provide a useful therapy against inflammation-associated depression.

Claims other papers make about this one

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

  • The severity of depression is associated with the secretion level of circulating cytokines and chemokines, which compromise the BBB and then activate central immune responses.

    “Our previous findings and those of others indicate that the severity of depression is associated with the secretion level of circulating cytokines and chemokines, which compromise the blood–brain barrier (BBB) and then activate central immune responses [10–13].”

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.
