项目摘要
ABSTRACT
Ixodes scapularis, commonly known as the deer tick, is the predominant tick vector of several
human pathogens including Borrelia burgdorferi, the Lyme disease agent and transmits the harbored
pathogens to the host during feeding. Vaccines against these tick-borne pathogens are not available.
This proposal will examine a new paradigm that suggests a critical role for tick salivary glycans
in provoking immune responses in the host critical to thwart tick feeding. This study will set the
tone for the development of tick salivary glycan-based vaccines to block tick feeding and prevent
transmission of multiple tick-transmitted pathogens to the host.
William Trager’s seminal observation showed that repeated tick infestations of non-permissive
hosts such as guinea pigs and rabbits provoke a brisk humoral immune response directed against critical
tick salivary components that results in thwarting tick feeding – a phenomenon referred to as acquired
tick-resistance. Our initial observations demonstrate that glycosylations on secreted tick salivary proteins
play a significant role in eliciting tick-resistance in guinea pigs. Glycans or carbohydrates decorations
present on several tick salivary proteins likely maintain the structure and function of the protein. These
glycan decorations potentially serve as “vector-associated-molecular patterns” (VAMPs) and elicit
glycan-specific immune responses that result in tick rejection. To develop this concept and to determine
the role of tick salivary glycans in the context of tick-host interactions we will:
A. Identify immunogenic salivary glycans targeted by tick-resistant guinea pig sera.
B. Identify salivary glycoproteins that contain immunogenic glycans.
C. Determine if immunization of guinea pigs with the glycans or glycoproteins might provoke tick-
resistance and consequently thwart tick feeding and prevent pathogen transmission. We will use B.
burgdorferi as an example of a tick-transmitted pathogen.
The results of this effort will illuminate a new facet of tick salivary proteins – the glycans that
decorate the proteins and the role of these glycans in modulating host immunity and offer new
approaches to impair tick feeding and prevent pathogen transmission.
抽象的
肩胛硬蜱,俗称鹿蜱,是多种蜱虫的主要媒介
人类病原体,包括伯氏疏螺旋体(Borrelia burgdorferi),莱姆病病原体,并传播所隐藏的病原体
在进食过程中将病原体传播给宿主。 目前还没有针对这些蜱传病原体的疫苗。
该提案将研究一种新的范式,该范式表明蜱唾液聚糖的关键作用
在宿主体内激发免疫反应,这对阻止蜱虫进食至关重要。 这项研究将设定
为蜱虫唾液聚糖疫苗的开发奠定基调,以阻止蜱虫进食并预防
将多种蜱传病原体传播给宿主。
威廉·特拉格的开创性观察表明,未经允许的蜱虫反复侵扰
豚鼠和兔子等宿主会引发针对关键疾病的快速体液免疫反应
蜱唾液成分导致蜱进食受阻——一种被称为后天性的现象
抗蜱虫性。 我们的初步观察表明,分泌的蜱唾液蛋白上存在糖基化
在引起豚鼠的蜱虫抗药性方面发挥着重要作用。 聚糖或碳水化合物装饰
存在于几种蜱唾液蛋白上,可能维持该蛋白的结构和功能。 这些
聚糖装饰有可能充当“载体相关分子模式”(VAMP)并引发
导致蜱排斥的聚糖特异性免疫反应。 发展这个概念并确定
蜱虫唾液聚糖在蜱虫与宿主相互作用中的作用,我们将:
A. 鉴定抗蜱豚鼠血清靶向的免疫原性唾液聚糖。
B. 鉴定含有免疫原性聚糖的唾液糖蛋白。
C. 确定用聚糖或糖蛋白免疫豚鼠是否可能引起蜱虫
抵抗力,从而阻止蜱虫进食并防止病原体传播。 我们将使用 B。
伯氏疏螺旋体作为蜱传播病原体的一个例子。
这项工作的结果将揭示蜱唾液蛋白的一个新方面——聚糖
修饰蛋白质以及这些聚糖在调节宿主免疫中的作用,并提供新的
削弱蜱虫进食和防止病原体传播的方法。
