项目摘要

DESCRIPTION (provided by applicant): The objective of this proposal is to further elucidate the role and interrelationship of cytokines and mucins in middle ear epithelium. It has been demonstrated that otitis media is a cytokine dependent process and that mucins are associated with chronic ear disease, middle ear defense mechanisms and pathogen viability. Data resulting from studies conducted during the Pi's ongoing NIDCD K08 award has demonstrated that the cytokines TNF-a, 11-1B and IL-6 upregulate mucin secretion and promote a differential expression of mucin genes with upregulation of gel-forming mucins in a chinchilla model. However, ongoing work and preliminary data presented in this proposal has demonstrated that mucin physiology in respiratory epithelium, such as the middle ear, is more complex than initially hypothesized. This is partially related to numerous recently identified mucin genes, which have unique properties, and which preliminary data suggest also have important functional roles in middle ear epithelial physiology and pathophysiology. This current proposal seeks funding to address several fundamental questions regarding cytokines, middle ear mucins and their interactions: 1) Which mucin genes are expressed in chinchilla and human middle ear epithelial cell cultures and do they correspond to in vivo middle ear mucin gene expression? 2) What effect do the inflammatory cytokines TNF-a, 11-1 p, IL-6 and IL-8 have on middle ear epithelium mucins at both the genomic and protein level? 3) Can the effects of these inflammatory cytokines be limited by inhibitors? and 4) What is the relative mucin gene expression in middle ear tissue from patients with otitis media compared with patients without otitis media and how does this compare with the experimental models proposed in this investigation? Answers to these questions will broaden our understanding of cytokine-mucin middle ear interactions, will provide information that is applicable to both chinchilla and human models, will extend our knowledge of the function of cytokines and mucins in otitis media pathophysiology, will provide specific clinical information regarding mucin expression in patients with and without otitis media history and will provide a platform to build future studies examining specific functionality of middle ear mucins. After a detailed understanding of middle ear cytokine-mucin interactions, models for determining novel interventions for otitis media through modulation of cytokine and mucin pathways can be developed. In addition, characterization of middle ear mucin physiology may lead to advances in the understanding mucosal defenses in the middle ear and otitis media. It is likely that completion of these aims will not only provide a clearer understanding of the pathology in otitis media but will benefit other scientists interested in middle ear biology, physiology and pathophysiology and will lead to advances in the treatment of otitis media and chronic ear disease which continues to be among the most prevalent diseases of childhood.
描述(由申请人提供):本提案的目的是进一步阐明细胞因子和粘蛋白在中耳上皮中的作用和相互关系。研究表明,中耳炎是一个依赖细胞因子的过程,粘蛋白与慢性耳病、中耳防御机制和病原体活力有关。在Pi正在进行的NIDCD K08奖期间进行的研究数据表明,细胞因子TNF-a, 11-1B和IL-6上调粘蛋白分泌,促进粘蛋白基因的差异表达,上调凝胶形成粘蛋白。然而,正在进行的工作和本提案中提出的初步数据表明,呼吸上皮(如中耳)中的粘蛋白生理比最初假设的更为复杂。这部分与最近发现的许多粘蛋白基因有关,这些基因具有独特的特性,并且初步数据表明它们在中耳上皮生理和病理生理中也具有重要的功能作用。本研究旨在研究细胞因子、中耳粘蛋白及其相互作用的几个基本问题:1)哪些粘蛋白基因在鼠和人中耳上皮细胞培养物中表达,它们是否与体内中耳粘蛋白基因表达相对应?2)炎症因子TNF-a、11- 1p、IL-6和IL-8在基因组和蛋白水平上对中耳上皮黏液蛋白有何影响?3)这些炎性细胞因子的作用是否会受到抑制剂的限制?4)中耳炎患者与非中耳炎患者中耳组织中黏液蛋白基因的相对表达情况如何,与本研究提出的实验模型有何比较?这些问题的答案将拓宽我们对细胞因子-黏液蛋白中耳相互作用的理解,将提供适用于栗鼠和人类模型的信息,将扩展我们对细胞因子和黏液蛋白在中耳炎病理生理学中的功能的认识。将为有或无中耳炎病史的患者提供有关粘蛋白表达的具体临床信息,并将为建立中耳粘蛋白特定功能的未来研究提供平台。在详细了解中耳细胞因子-粘蛋白相互作用后,可以开发通过调节细胞因子和粘蛋白途径确定中耳炎新干预措施的模型。此外,中耳黏液蛋白生理学的表征可能会导致对中耳粘膜防御和中耳炎的理解取得进展。这些目标的完成很可能不仅会提供对中耳炎病理的更清晰理解,而且会使其他对中耳生物学、生理学和病理生理学感兴趣的科学家受益,并将导致中耳炎和慢性耳部疾病的治疗取得进展,这些疾病仍然是儿童最常见的疾病之一。
