项目摘要
ABSTRACT
Support is requested for an interdisciplinary effort to understand the key molecular and
developmental events that regulate blood and vascular cells in inflammation, hemostasis
and thrombosis with a focus on adhesive signaling. The four Projects will: 1) Test the
hypothesis that direct interactions between Rap1 and talin1 plays an important role in
platelet, leukocyte, and endothelial cell functions in inflammation, hemostasis and
thrombosis. 2) Use newly developed imaging modalities to enable quantitative dynamic
footprinting of the surface of neutrophils in contact with substrate to assess adhesion
receptor clustering and conformation in response to specific molecular adaptor-adhesion
receptor interactions. A particular focus is the structure-function of kindlin-3, the gene
mutated in human leukocyte adhesion deficiency Type 3, and its relationship to talin. 3)
An Early Stage Investigator will test the hypothesis that genetic inactivation of Krit1 or
Heg1 in adult mice will protect against experimental inflammation or thrombosis. In
collaboration with a structural biologist, he will extend studies to test the feasibility of
pharmacologically disrupting the HEG1-KRIT1 complex to mimic the effects of genetic
inactivation of these genes. 4) To assess the role of SHARPIN and associated
components of the LUBAC linear ubiquitination complex in the functions of platelets and
endothelial cells in inflammation, hemostasis, and thrombosis. This project will test the
hypothesis that this newly-identified regulator of platelet and endothelial cell functions
contributes to inflammation, hemostasis, and thrombosis. A scientific core unit, led by a
world leader in murine models of inflammation, hemostasis, and thrombosis, will provide
the individual projects with in vivo models and expertise required to establish the patho-
physiological relevance of these novel molecular mechanisms.
摘要
需要支持跨学科的努力,以了解关键的分子和
在炎症、止血中调节血液和血管细胞的发育事件
和血栓形成,重点是粘附信号。这四个项目将:1)测试
假设Rap 1和talin 1之间的直接相互作用在
血小板、白细胞和内皮细胞在炎症、止血和
血栓形成2)使用新开发的成像模式,
与基质接触的中性粒细胞表面足迹法,以评估粘附
受体聚集和构象对特异性分子衔接子粘附的响应
受体相互作用一个特别的焦点是kindlin-3基因的结构-功能,
突变的人白细胞粘附缺陷3型,及其与talin的关系。第三章
早期研究者将检验Krit 1或
Heg 1在成年小鼠中可以防止实验性炎症或血栓形成。在
与结构生物学家合作,他将扩大研究,以测试的可行性,
干扰HEG 1-KRIT 1复合物以模拟遗传效应
这些基因的失活。4)评估SHARPIN及相关的作用
血小板功能中LUBAC线性泛素化复合物的组分,
炎症、止血和血栓形成中的内皮细胞。该项目将测试
假设这种新发现的血小板和内皮细胞功能调节剂
有助于炎症、止血和血栓形成。一个科学核心单位,由一个
炎症、止血和血栓形成小鼠模型的世界领导者,将提供
具有体内模型和建立病理学所需的专业知识的各个项目,
这些新的分子机制的生理相关性。
