摘要

在本期的《结构》杂志上，Nguyen等人1发现来自同一患者的心脏和神经的转甲状腺素（TTR） V30M变体的淀粉样原纤维具有结构同质性。这一发现对于提高我们对V30M-TTR淀粉样蛋白沉积的理解至关重要，V30M-TTR淀粉样蛋白沉积导致致命的ATTRv淀粉样变性。

Does the structure of transthyretin amyloid fibrils vary depending on the organ of accumulation?

In this issue of Structure, Nguyen et al.¹ reveal that amyloid fibrils of the transthyretin (TTR) V30M variant from the heart and nerves of the same patient exhibit structural homogeneity. This finding is crucial for advancing our understanding of V30M-TTR amyloid deposition, which leads to fatal ATTRv amyloidosis.

期刊介绍： Structure aims to publish papers of exceptional interest in the field of structural biology. The journal strives to be essential reading for structural biologists, as well as biologists and biochemists that are interested in macromolecular structure and function. Structure strongly encourages the submission of manuscripts that present structural and molecular insights into biological function and mechanism. Other reports that address fundamental questions in structural biology, such as structure-based examinations of protein evolution, folding, and/or design, will also be considered. We will consider the application of any method, experimental or computational, at high or low resolution, to conduct structural investigations, as long as the method is appropriate for the biological, functional, and mechanistic question(s) being addressed. Likewise, reports describing single-molecule analysis of biological mechanisms are welcome. In general, the editors encourage submission of experimental structural studies that are enriched by an analysis of structure-activity relationships and will not consider studies that solely report structural information unless the structure or analysis is of exceptional and broad interest. Studies reporting only homology models, de novo models, or molecular dynamics simulations are also discouraged unless the models are informed by or validated by novel experimental data; rationalization of a large body of existing experimental evidence and making testable predictions based on a model or simulation is often not considered sufficient.
