中文简介: | 生命科学经历了从分子水平到系统水平的转变,促进了我们对复杂生物系统(如免疫系统和代谢系统)理解的新质量的发展。该项目将基础研究与研究领域的应用联系起来,这些领域主要与健康有关。该项目的重点是了解人类机体在分子水平上对细菌感染和构象疾病的反应,以及对微生物代谢的了解,以改进各种药学上感兴趣的产品。在LPS受体的研究中,我们将研究细胞外(MD-2,TLR4,CD14)和细胞内受体。在分子水平上理解相互作用可以产生新的化合物,这些化合物可以用来中和过度的免疫反应。本研究旨在阐明所谓的“PAMP受体”的生化特异性,即识别致病微生物分子模式的受体。基于结构-活性关系(sar),我们计划开发新的(lipo)肽,并确定细菌和真核细胞膜的选择性差异。在健康领域,我们也在研究疾病,特别是与蛋白质构象变化相关的传染性海绵状脑病(TSE)。单克隆抗体已被确定为诊断工具以及治疗。通过免疫化学与蛋白质方法和结构生物化学的结合,我们对识别与克雅氏病相关的朊蛋白(prpsc)致病形式的抗体的特异性进行了第一步分析。这一工具和其他工具将使我们能够改进疾病的检测和早期诊断,同时有助于理解TSE的传染性。该项目还涉及工业微生物的初级代谢研究,特别是6-磷酸果糖激酶(pfka),其性质在翻译后修饰过程中发生了显著变化。我们打算将编码更活跃酶的缩短基因转移到其他商业上重要的微生物中。我们将开发新的荧光细胞内生物传感器,以监测事件,特别是在真核细胞。我们将重点分析活细胞内的钙、cAMP和ph。 |
课程简介: | Life sciences experience the transition from molecular to the systemic level, fostering the development of a new quality in our understanding of complex biological systems such as immune and metabolic system. Program connects basic research with application in the areas of research, which have primarily relevance to the health. The emphasis of the program is on the understanding of the response of the human organism to bacterial infections and conformational diseases at the molecular level and understanding of the microbial metabolism directed towards the improvement of the various pharmaceutically interesting products. Within the research of the LPS receptors we will investigate the extracellular (MD-2, TLR4, CD14) as well as intracellular receptors. Understanding of interactions at the molecular level can lead to new compounds, which might be used to neutralize the excessive immune response. The aim of this research is to elucidate the biochemical specificity of the so called “PAMP receptors”, i.e. receptors that recognize the molecular patterns of pathogenic microorganisms. Based on the structure-activity relationship (SAR) we plan to develop new (lipo)peptides and establish the differences in the selectivity between bacterial and eukaryotic membranes. In the area of health we are also investigating diseases, particularly transmissible spongiform encephalopathies (TSE) connected to conformational changes of proteins. Monoclonal antibodies have been established as diagnostic tool as well as for the therapy. By the combination of immunochemistry with methods of protein and structural biochemistry we made the first step analyzing the specificity of antibodies that recognize the pathogenic form of prion protein (PrPSc), linked to Creutzfeld-Jakob disease. This and other tools will allow us to improve the detection and early diagnostics of disease and in parallel to contribute to the understanding of the infectivity of TSE. Program also involves the research of primary metabolism of industrial microorganisms, particularly 6-phosphofructo-kinase (pfkA), whose properties significantly change during the posttranslational modification. We intend to transfer the shortened gene encoding more active enzyme into other commercially important microorganisms. We will develop the new fluorescent intracellular biosensors to monitor the events particularly in eukaryotic cells. We will put the emphasis on the analysis of Ca, cAMP and pH inside of living cells. |
