Vagotomy attenuates behavioural effects of interleukin-1 injected peripherally but not centrally

Abstract

Peripheral and central injections of recombinant rat interleukin-1 beta (IL-1 beta) have been shown to decrease social exploration in rats. To test the involvement of vagal afferents in the communication between the immune system and the brain, sham-operated and vagotomized rats were injected peripherally or centrally with physiological saline or IL-1 beta 4 weeks after surgery. Vagotomy attenuated the depression in social exploration induced by i.p. administration of IL-1 beta (15 micrograms) but did not alter the behaviour-depressing effects of an intracerebroventricular (i.c.v.) injection of IL-1 beta (45 ng). These results confirm the role of vagal afferent nerves in the transmission of an immune message from the periphery to the brain, and show that vagotomy does not impair the direct sensitivity of the brain itself to immune signals.

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

  • Preclinical studies show that vagotomy blocks or alters the dynamics of peripheral immune system communication to the CNS.

    “Preclinical studies of neural communication between the CNS and the peripheral immune system have targeted the vagus nerve, and demonstrate that vagotomy (sub-diaphragmatic transection of the vagus nerve) blocks or alters the dynamics of peripheral immune system communication to the CNS”

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.
