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圆 β-桶模型,并比较其尺寸的图像平均电子显微照片, β-淀粉样蛋白42.较小的低聚物具有6、8、12、16和18个单体。这些珠子串 一起形成项链状珠状环状原纤维(bAPF)。这些逐渐演变成 平滑型有源滤波器,其中S3 β筒在一侧或两侧被形成的β筒屏蔽 从S1和S2段。在第二部分中,我们扩展了寡聚体的β-淀粉样肽模型, 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,其与帕金森病有关。
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.
