DESCRIPTION (provided by applicant): Thyroid-related eye disease (TED) is an important public health burden that causes loss of productivity and reduces quality of life. TED can lead to chronic debilitating pain and headaches, double vision, corneal exposure, dry eyes, secondary glaucoma and compressive optic neuropathy, and carries a significant risk of vision loss. The pathogenesis of TED is incompletely understood, but involves the activation of orbital fibroblasts by an unidentified thyroid-related cell signal. Activated fibroblasts in turn secrete large quantities of hyaluronan, causing significant swelling of orbital tissues and especially extraocular muscles. In addition, orbital fibroblasts mediate a severe inflammatory orbitopathy that leads to orbital fibrosis. Orbital fibroblasts can also proliferate and differentiate into adipocytes, filling the orbit with excess fat. The combination of tissue swelling, scarring and adipogenesis leads to exophthalmos and a compartment syndrome whereby normal orbital tissues are compressed by the abnormal ones, leading to compressive optic neuropathy, secondary glaucoma and chronic orbital headaches. Exophthalmos can lead to chronic dry eyes and corneal exposure. The swelling and fibrosis of muscles can lead to ocular misalignment and diplopia. Orbital fibroblasts are derivatives of the neural crest, a transient population of pluripotent cells that differentiate into a broad range of tissues during embryogenesis. The unique behavior of orbital fibroblasts in TED may be partially caused by their embryologic neural crest origins. The main hypothesis of this project is that embryologic processes that occur during the development of the orbital neural crest are important in the pathogenesis of TED. The biology of the orbital neural crest is unknown and largely unexplored. The goal of this research project is to utilize the genetic and cell biology tools available in zebrafish to shed new light on the genetics and cell biology of orbital neural crest-derived tissues, in order to lead to improved diagnostic and treatment for TED and other orbital diseases.

描述（由申请人提供）：甲状腺相关眼病 (TED) 是一种重要的公共卫生负担，会导致生产力下降并降低生活质量。 TED 可导致慢性衰弱性疼痛和头痛、复视、角膜暴露、干眼、继发性青光眼和压迫性视神经病变，并具有视力丧失的显着风险。 TED 的发病机制尚不完全清楚，但涉及一种未识别的甲状腺相关细胞信号激活眼眶成纤维细胞。激活的成纤维细胞反过来分泌大量透明质酸，导致眼眶组织，尤其是眼外肌显着肿胀。此外，眼眶成纤维细胞介导严重的炎症性眼眶病，导致眼眶纤维化。眼眶成纤维细胞也可以增殖并分化为脂肪细胞，使眼眶充满多余的脂肪。组织肿胀、疤痕和脂肪生成的结合导致眼球突出和筋膜室综合征，正常眼眶组织被异常组织压迫，导致压迫性视神经病变、继发性青光眼和慢性眼眶头痛。眼球突出可导致慢性干眼症和角膜暴露。肌肉肿胀和纤维化会导致眼球错位和复视。 眼眶成纤维细胞是神经嵴的衍生物，神经嵴是多能细胞的瞬时群体，在胚胎发生过程中分化成广泛的组织。 TED 中眼眶成纤维细胞的独特行为可能部分是由其胚胎神经嵴起源引起的。该项目的主要假设是，眼眶神经嵴发育过程中发生的胚胎学过程对于 TED 的发病机制很重要。眼眶神经嵴的生物学特性尚不清楚，而且很大程度上尚未被探索。该研究项目的目标是利用斑马鱼现有的遗传和细胞生物学工具，为眼眶神经嵴衍生组织的遗传学和细胞生物学提供新的线索，从而改进 TED 和其他眼眶疾病的诊断和治疗。 甲状腺相关眼病是一种重要的公共卫生负担，会导致生产力下降和生活质量下降。这项研究的目标是利用斑马鱼（一种脊椎动物模型系统）中可用的遗传和细胞生物学工具，为眼眶神经嵴衍生组织的生物学提供新的线索，从而改进 TED 和其他眼眶疾病的诊断和治疗。
