membrane receptor meaning in Chinese
膜受体
Examples
- Plasma membrane receptor of glucocorticoid on the neurons , which is responsible for the rapid action of glucocorticoid
,在半个世纪的科研生涯中，态度严谨，一丝不苟，精益求精，硕果累累。 - However , the receptor and translocation domains of the colicin ia can only recognize the inner and outer membrane receptors of the escherichia coli , therefore the wild type colicin ia can not be developed into antibiotics against other types of bacteria
然而由于其信号识别结构域只能识别大肠杆菌外膜和内膜上的特异受体，因此野生型大肠菌素难以拓展成为对抗它种细菌的抗菌素。 - Cell adhesion to surface of the substrate is essential to development of the anchorage - dependent cells . only after adhering to surface followed by spreading can cells develop and proliferate . most synthetic polymers used as orthopaedic matrix substitute present hydrophobicity , which may correlates to the low degree of cell attachment . modification with cell adhesion protein / peptides can be benificial to the cell adhesion on polymers and then affect the cell proliferation and differentiation . cell attachment to substrate is primarily mediated by integrins , a widely expressed family of heterodimeric surface receptors . most extrcellular matrix proteins such as fibronectin , osteopontin , collagen type i , bone sialoprotein and vitronectin contain an arg - gly - asp ( rgd ) sequence which is specific to the fixation of cell membrane receptors like integrin . the main aim of this research is to measure , assess adhesion , proliferation of rabbit marrow stromal cells ( mscs ) on the polymers coated by fibronectin , collagen type i or biotie gen , which includes : ( 1 ) biologic characteristics of rabbit mscs were observed by two types of separating method in primary culture . ( 2 ) adhesion , proliferation and differentiation of mscs cultured on polymers coated with biotiegen were assessed . ( 3 ) also , adhesion , proliferation and differentiation of mscs were assessed on plga film or porous plga substrates coated with fibronectin , or collagen type i respectively . ( 4 ) bone formation was observed on the porous plga substrates coated with collagen type i in vivo . this research aims to give new way to make novel synthetic bone with cell adhesion and high bone induction capabilities
因此将这些蛋白包被、固定到材料表面，观察骨组织工程种子细胞mscs细胞的粘附、生长特性是本研究的中心环节，并从以下方面进行探讨： ( 1 )采用不同原代细胞分离方法，研究其对mscs细胞的生物学特性影响。 ( 2 )检测基因胜肽胶对mscs细胞粘附、增殖及分化的影响。 ( 3 )分别采用型胶原及纤维粘连蛋白( fibronectin ， fn )包被聚乙醇酸-乳酸共聚物( poly ( 1actide - co - glycolide ) ， plga )膜及多孔块型plga材料，观察细胞在单层或三维培养状态下，型胶原及fn对mscs细胞粘附、增殖及向成骨细胞分化效应及能力。 - In the 1990s , the pheromones of gram - positive bacteria , which regulates the growth and toxin secretion of the same type bacteria , were identified they were peptides consisted by dozens of amino acids . the pheromones can auto - recognize membrane receptor of the identical types of bacteria . we had constructed a fusion protein named pheromonicin by introducing a staphylococcal pheromone agrd at the c - terminal of the colicin ia
丘小庆等利用信息素的自主导向特性和大肠菌素ia的致死性通道特性构建了由金黄色葡萄球菌信息素agrd和大肠菌素ia组成的融合蛋白，命名为pheromonicin ，该蛋白表现出了信息素和大肠菌素ia都不具有的抗金黄色葡萄球菌活性。
