| Outline of Final Research Achievements |
The pathogenesis of postviral olfactory disorder(PVOD) has not been clarified. In this study, we focused on the secondary damage of olfactory neuroepithelium caused by host immune responses and the regeneration of olfactory neuroepithelium after the tissue damage caused by methimazole. Intranasal administration of TLR7 ligands didn't induce the inflammatory cells infiltration and the olfactory neuroepithelial damage. In macrophage depletion model mice, the olfactory neuroepithelial regeneration was incomplete.It was suggested that macrophages were deeply involved in the regeneration of the olfactory neuroepithelium.
