| pubmed-article:17706967 | pubmed:abstractText | Repeated exposure to lipopolysaccharide (LPS) induces desensitization of hypothalamus-pituitary-adrenal axis (HPA) responses and hypophagia. We investigated the interplay between the neural circuitries involved in the control of food intake and HPA axis activity following single or repeated LPS injections. Male Wistar rats received a single or repeated i.p. injection of LPS (100 microg/kg) for 6 days and were subdivided into four groups: 6 saline, 5 saline+1 LPS, 5 LPS+1 saline and 6 LPS. Animals with a single exposure to LPS showed increased plasma levels of ACTH, CORT, PRL, TNF-alpha and also CRF mRNA in the paraventricular nucleus of the hypothalamus. These animals exhibited a reduced food intake and body weight associated with an increase of CART expression in the arcuate nucleus (ARC). Leptin plasma levels were not altered. On the other hand, repeated LPS administration did not alter ACTH, CORT, PRL and TNF-alpha, but it reduced leptin level, compared to single LPS or saline treatment. Furthermore, repeated LPS administration did not increase CRF or CART mRNA expression. Food intake and weight gain after repeated LPS injections were not different from saline-treated animals. There was no change in NPY and POMC mRNA expression in the ARC after single or repeated injections of LPS. In conclusion, desensitization induced by repeated exposure to LPS involves the blockade of HPA axis activation and anorexigenic response, which are both associated with an unresponsiveness of TNF-alpha production and CRF and CART expression in the hypothalamus. | lld:pubmed |
