项目摘要
PROJECT SUMMARY
Taste loss can lead to malnutrition, weight loss, and depression. In addition, changes in taste are a symptom of
poor health. This cyclical relationship between taste and health highlights the importance of research aimed at
understanding taste loss in both health and disease. Research on taste loss will provide new approaches in the
prevention, diagnosis, and treatment of disease. It is well-documented that infections and autoimmune
conditions are accompanied by changes in chemosensory perception including changes in taste. However,
currently we know little about how taste bud regeneration is regulated, and there is no effective treatment for
taste loss. Our recent research indicates that inflammation, characterized by induction of inflammatory
cytokines and infiltration and activation of immune cells, contributes significantly to taste dysfunction. We
hypothesize that inflammation, particularly through the action of the inflammatory cytokine interferon-γ (IFN-γ),
contributes to taste loss by inducing cell death and inhibiting taste bud cell renewal, and that resolution of
inflammation promotes taste bud regeneration. IFN-γ can be produced by various types of immune and
nonimmune cells in response to infections and autoimmunity. Its levels in taste tissues are markedly increased
in an autoimmune disease model with taste loss. Yet, whether IFN-γ directly contributes to taste loss has not
been determined. In this project, we propose to investigate the role of inflammation, especially IFN-γ, in taste
loss using both a transgenic approach and a clinically relevant respiratory viral infection model. We will then
use these taste loss models to study the mechanisms of taste bud regeneration. This research will test
mechanistic hypotheses of how inflammation and infection cause taste loss, and how taste responses recover.
To underscore the importance of research investigating the link between inflammation, disease, and taste loss,
a considerable number of COVID-19 patients experience taste dysfunction. Although most cases of taste loss
are temporary, including taste loss associated with SARS-CoV-2 infection, long-term taste loss can occur in
some patients. Thus, insights from this research will be informative to better understand taste loss in general,
as well as taste loss associated with COVID-19.
项目总结
味觉缺失会导致营养不良、体重减轻和抑郁。此外,口味的变化也是一种症状
身体不好。味觉和健康之间的这种循环关系突显了旨在
了解味觉减退对健康和疾病的影响。味觉减退的研究将提供新的途径
疾病的预防、诊断和治疗。有充分的证据表明感染和自身免疫
这种情况伴随着化学感觉的变化,包括味觉的变化。然而,
目前,我们对味蕾再生的调控知之甚少,也没有有效的治疗方法。
味觉减退。我们最近的研究表明,炎症,其特征是诱导炎症
细胞因子和免疫细胞的渗透和激活,在很大程度上导致了味觉功能障碍。我们
假设炎症,特别是通过炎症细胞因子干扰素-γ(干扰素-γ)的作用,
通过诱导细胞死亡和抑制味蕾细胞更新而导致味觉丧失,而解决
炎症促进味蕾再生。干扰素-γ可由多种类型的免疫和
非免疫细胞对感染和自身免疫的反应。它在味觉组织中的水平显著增加
在味觉丧失的自身免疫性疾病模型中。然而,干扰素-γ是否直接导致味觉丧失还没有。
已经确定了。在这个项目中,我们建议研究炎症,特别是干扰素-γ在味觉中的作用。
使用转基因方法和临床相关的呼吸道病毒感染模型的损失。到时候我们会的
利用这些味觉丧失模型来研究味蕾再生的机制。这项研究将检验
炎症和感染如何导致味觉丧失,以及味觉反应如何恢复的机械假说。
为了强调研究炎症、疾病和味觉丧失之间联系的重要性,
相当数量的新冠肺炎患者经历了味觉障碍。尽管大多数味觉丧失的病例
是暂时的,包括与SARS-CoV-2感染有关的味觉丧失,长期的味觉丧失可能发生在
一些病人。因此,这项研究的见解将有助于更好地理解味觉丧失的一般情况,
以及与新冠肺炎相关的味觉丧失。
