中文摘要
在此期间,我们发表了两篇论文。首先,我们提出了一系列同心β桶模型,并将它们的尺寸与β-淀粉样蛋白的图像平均电子显微照片进行比较。较小的低聚物具有6、8、12、16和18个单体。这些珠子串在一起形成项链状珠状环状原纤维(bAPF)。这些逐渐演变成光滑的APF,其中S3 β桶在一侧或两侧被S1和S2段形成的β桶屏蔽。在第二,我们扩展我们的β-淀粉样肽模型的寡聚体,环状原纤维,管状原纤维,脂蛋白,和离子通道的α,β和γ突触核蛋白家族,这已牵连在帕金森氏病。
英文摘要
In this period we published two papers. In the first we proposed a range of concentric beta-barrel models and compare their dimensions to image-averaged electron micrographs of Beta-Amyloid42. The smaller oligomers have 6, 8, 12, 16, and 18 monomers. These beads string together to form necklace-like beaded-annular-protofibrils (bAPFs). These gradually morph into smooth-APFs in which a S3 beta-barrel is shielded on one or both sides by beta-barrels formed from S1 and S2 segments. In the second we extend our beta-amyloid peptide models of oligomers, annular protofibrils, tubular protofibrils, lipoproteins, and ion channels to the alpha, beta and gamma synuclein family which has been implicated in Parkinson's Disease.
