Abstract

The behavioral effects of peripherally administered interleukin-1beta (IL-1beta) are mediated by the production of cytokines and other proinflammatory mediators at the level of the blood-brain interface and by activation of neural pathway. To assess whether this action is mediated by NFkappaB activation, rats were injected into the lateral ventricle of the brain with a specific inhibitor of NFkappaB activation, the NEMO Binding Domain (NBD) peptide that has been shown previously to abolish completely IL-1beta-induced NFkappaB activation and Cox-2 synthesis in the brain microvasculature. NFkappaB pathway inactivation significantly blocked the behavioral effects of intraperitoneally administered IL-1beta in the form of social withdrawal and decreased food intake, and dramatically reduced IL-1beta-induced c-Fos expression in various brain regions as paraventricular nucleus, supraoptic nucleus, and lateral part of the central amygdala. These findings strongly support the hypothesis that IL-1beta-induced NFkappaB activation at the blood-brain interface is a crucial step in the transmission of immune signals from the periphery to the brain that underlies further events responsible of sickness behavior.

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.
