The Importance of Being Imperfect: Structure and Function of Bacterial Amyloid

Advanced Science, EarlyView.
Functional bacterial amyloids such as CsgA and FapC have been widely studied to understand the relationship between aggregation and function. The recently solved structure of FapC reveals a Greek‐key motif in which extensive hydrogen bonding and packing interactions formed by residues in conserved imperfect repeats stabilize a β‐solenoid core.

In Situ Assembly of Transformable Monopeptide on Activated Neutrophils Attenuates NETs‐Induced Hepatocellular Carcinoma Metastasis by Disrupting NE Nuclear Translocation

Advanced Science, EarlyView.
Activated neutrophils release extracellular traps (NETs) that promote tumor metastasis. FTP‐NPs are develpoed, a peptidic nanomaterial that binds NE on neutrophil membranes, forming NE‐fibril clusters that deactivate NE and prevent NETs formation. This strategy reduces metastasis and enhances the anti‐tumor immune response by targeting NE subcellular ...

Association between Human Leukocyte Antigen Alleles and Neuropathological Outcomes in Lewy Body Disease

Annals of Neurology, EarlyView.
Objective Lewy body disease (LBD) is a complex neurodegenerative disorder characterized by the accumulation of misfolded α‐synuclein in the brain. Neuroinflammation has long been implicated in LBD pathogenesis, and recent genetic studies in Parkinson's disease (a clinical manifestation of LBD) have shown consistent association with the human leukocyte ...

Photoswitchable Peptides as Molecular Tools to Encode Structural Order and Disorder in Intracellular Assemblies

Angewandte Chemie International Edition, EarlyView.
We present a photoswitchable peptide conjugate which exhibits isomerism‐dependent self‐assembly: the planar trans‐isomer assembles into well‐ordered nanofibers while the non‐planar cis‐isomer yields disordered aggregates. Our study offers a direct visualization on the effects of structure formation inside living cells.
