| Ana Guijarro, Alessandro Laviano, Michael M Megui. Hypothalamic integration of immune function and metabolism. Progress in brain research. vol 153. 2006-11-28. PMID:16876587. |
immunohistochemical studies have shown a decrease in neuropeptide y (npy) and dopamine (da) and an increase in serotonin concentration in tumor-bearing rats, in first- and second-order hypothalamic nuclei, while tumor resection reverted these changes and normalized food intake, suggesting negative regulation of npy and da systems by cytokines during anorexia, probably mediated by serotonin that appears to play a pivotal role in the regulation of food intake in cancer. |

the sum of these data support the concept that immune cell-derived cytokines are closely related with the regulation of metabolism and have both central and peripheral actions, inducing anorexia via hypothalamic anorectic factors, including serotonin and dopamine, and inhibiting npy leading to a reduction in food intake and body weight, emphasizing the interconnection of the immune and neuroendocrine systems in regulating metabolism during infectious process, cachexia and obesity. |

furthermore, based on the similarities of responses of pvn-lesioned and sham control rats to the anorexigenic agents mtii and leptin and the hypersensitivity of lesioned rats to npy, we conclude that the pvn is not essential for npy stimulation of food intake or for melanocortin suppression of food intake and that npy and melanocortin receptors outside of the pvn are sufficient to produce these effects. |
