Outline of Final Research Achievements |
(1) Caloric restriction exacerbated regeneration of the olfactory neuroepithelium after injury by methimazole. Downregulation of proliferative activity of basal cells in neuroepithelium by caloric restriction appeared to play important role in these findings. (2) During the regeneration of the olfactory neuroepithelium, lipid mediators generated through metabolism by 12/15 lipoxygenase (12/15 LOX) was increased. 12/15 LOX-positive cells were transiently infiltrated into the regenerating olfactory mucosa, suggesting that the composition of tissue fatty acid is associated with the regenerative process of the olfactory neuroepithelium. (3) Intranasal administration of cigarette smoke solution (CSS) suppressed the recovery of neuroepithelium after injury. CSS administration decreased the ORN injury-induced IGF-1 expression. Administration of recombinant human IGF-1 prevented the CSS-induced suppression of neuroepithelial recovery.
