| Outline of Final Research Achievements |
Eating disorders are observed mainly in adolescent women, which the characteristics are the distortion of recognition against their figures, the loss of their self-respect, and anxiety induced by the lack of understanding of their family and friends. However effective cure has never been found. The present study assessed the association between anorexia and bone marrow-derived (BMD) cells in activity based anorexia model mice to elucidate the mechanisms under the eating disorders. In ABA model mice body weight was decreased and the ability of novel object recognition was impaired. mRNA expressions of orexigenic peptides: NPY and AgRP were increased but the expression of receptor to orexigenic peptide: NPY2R was decreased. We observed the infiltration of BMD cells into the hypothalamus of ABA model mice. Our results suggest that BMD cells contribute to the cause of eating disorders.
