Ca<sub>V</sub>2.1 mediates presynaptic dysfunction induced by amyloid β oligomers

1 week 3 days ago
Synaptic dysfunction is an early pathological phenotype of Alzheimer's disease (AD) that is initiated by oligomers of amyloid β peptide (Aβ(o)s). Treatments aimed at correcting synaptic dysfunction could be beneficial in preventing disease progression, but mechanisms underlying Aβ(o)-induced synaptic defects remain incompletely understood. Here, we uncover an epithelial sodium channel (ENaC) - Ca(V)2.3 - protein kinase C (PKC) - glycogen synthase kinase-3β (GSK-3β) signal transduction pathway...

Targeted degradation of α-Synuclein using an evolved botulinum toxin protease

1 week 3 days ago
There is considerable interest in the targeted degradation of proteins implicated in human disease. The use of sequence-specific proteases for this purpose is severely limited by the difficulty in engineering the numerous enzyme-substrate interactions required to yield highly selective proteases while maintaining catalytic activity. Herein, we report a strategy to evolve a protease for the programmed degradation of α-Synuclein, a presynaptic protein closely linked to Parkinson's disease. Our...

Ordered zinc electrodeposition from single-crystal units to polycrystalline stacking within solid-electrolyte interphase in battery anodes

1 week 3 days ago
Controlling Zinc (Zn) nucleation and subsequent crystal growth are critical for long lifespan aqueous zinc metal batteries. However, the concurrent side reactions and unstable solid-electrolyte interphase (SEI) formations impedes the continuous Zn metal electrodeposition. Herein, induced by a well-designed organic/inorganic dual-phase SEI, we realize ordered zinc electrodeposition of polycrystalline stackings from single-crystal building blocks. The uncommon SEI with appropriate ion transport...

Religiosity, Religious Beliefs, and Cognitive Impairment Among Black and White Men With Modest Incomes

1 week 3 days ago
ObjectiveThe objective of this study was to examine the association between religious practices, beliefs, and cognitive impairment among Black and White men with modest incomes in the 2016 Health and Retirement Study.MethodsData were drawn from Black and White men who reported annual incomes at or below $50,000 (n = 926). The primary outcome was any cognitive impairment, a dichotomous variable derived from a modified version of the Telephone Interview for Cognitive Status. The religious...
