In this study, we revealed that subcutaneous administration of rotenone caused progressive neurodegeneration in the olfactory bulb and myenteric plexus of ascending colon, in addition to the nigrostriatal pathway, but not in the thoracic cord. Rotenone treatment also induced increases in the number of astrocytes in a time- and region-specific manner. These results suggested that neurodegeneration after rotenone exposure was region-specific, but did not spread retrogradely from the peripheral tissue to nigrostriatal pathway, and that glial activation could be related to rotenone-induced neurotoxicity. Using primary cultured cells, we showed that rotenone induced activation of NFAT, secretion of inflammatory cytokines, and decreased metallothionein release in/from rotenone-treated mesencephalic astrocytes, which caused dopaminergic neurotoxicity. These results suggest possible involvement of glial dysfunction in dopaminergic neurotoxicity induced by environmental toxin rotenone.
