Abstract

Tumor necrosis factor alpha (TNF-alpha) is a cytokine that is responsible, in part, for several aspects of the acute-phase response to inflammation, including the generation of fever. TNF-alpha has direct effects on central nervous system neurons deep within the hypothalamus that are involved in producing the febrile response, but the blood-brain barrier prevents circulating TNF-alpha from having access to these sites. We therefore have hypothesized that TNF-alpha may be produced in the brain and used as a mediator in the cerebral components of the acute-phase response. We used in situ hybridization to determine the distribution of production of TNF-alpha mRNA in the mouse brain after systemic administration of lipopolysaccharide. During the initial phase of fever, hybridization was observed in perivascular cells and neurons in circumventricular organs, including the vascular organ of the lamina terminalis, median eminence, and area postrema, as well as along the ventral surface of the medulla; hybridization was also prominent over many cell in the meninges. During the late phase of the response, hybridization was observed over neurons in the pericircumventricular nuclei such as the anteroventral periventricular and arcuate nuclei of the hypothalamus and the nucleus of the solitary tract. TNF-alpha produced by a cascade of neurons within the brain may participate in the complex autonomic, neuroendocrine, metabolic, and behavioral responses to infection and 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.
