Contribution of Neuroinflammation to the Pathogenesis of Cancer Cachexia by Alessio Molfino, Gianfranco Gioia, Filippo Rossi Fanelli, Alessandro Laviano

“…Robust data indicate that, during cancer, functional modifications within brain areas regulating energy homeostasis contribute to the onset of anorexia, reduced food intake, and increased catabolism of muscle mass and adipose tissue. In particular, functional changes are associated with increased hypothalamic concentration of proinflammatory cytokines, which suggests that neuroinflammation may represent the adaptive response of the brain to peripheral challenges, including tumor growth. …”
