Peptide‐based antibacterial nanoplatforms: Design principles, stimuli‐regulated behaviors, and applications

Responsive Materials, EarlyView.
Peptide‐based antibacterial nanoplatforms, encompassing self‐assembled peptides and peptide‐engineered inorganic, polymeric, and lipid nanocarriers, are systematically reviewed. The article highlights design principles and stimuli‐responsive regulation for improving peptide stability, delivery efficiency, and antibacterial performance.

Consequences of the interaction of amyloid beta with amyloid binding alcohol dehydrogenase and the receptor for advanced glycation end products

, 2008
Amyloid beta (Aβ) has been postulated to be the principle initiator of the pathogenesis of Alzheimer’s disease (AD). Therefore, understanding the underlying mechanisms of Aβ induced neurotoxicity in the early stages of AD would be essential for finding ...

Potential contribution of exosomes to the prion-like propagation of lesions in Alzheimer’s disease

Frontiers in Physiology, 2012
Since the discovery of prion diseases, the concept that a transmissible pathogen could be a protein has emerged. As such, this transmissible protein agent can transfer its pathological mis-folded shape to the same but normally folded protein thus leading

Generation of amyloid β protein from its precursor is sequence specific

Neuron, 1995
Cerebral deposition of amyloid beta protein (A beta) is an early and critical feature of Alzheimer's disease. Here we analyze the substrate requirements of proteases ("beta-secretases") that cleave the beta-amyloid precursor protein (beta APP) at the N-terminus of A beta (Asp-597 of beta APP695) in intact human cells.

A Prodrug Approach for Activity‐Based Chemical Modulation toward Multiple Pathological Targets in Alzheimer's Disease

Small, EarlyView.
We present a pathology‐responsive, activity‐based prodrug strategy that tackles multiple hallmarks of Alzheimer's disease (AD). Rationally designed BE compounds convert under oxidative stress into redox‐active aminophenols, neutralizing ROS and redirecting both metal‐free and metal‐bound Aβ aggregation.

The copper-amyloid-beta-peptide complex of Alzheimer’s disease: affinity, structure, fibril formation and toxicity

, 2010
PhDSenile plaques of Alzheimer’s disease (AD) patients are composed primarily of the amyloid-β-peptide peptide (Aβ), and within these plaques Cu2+ ions are found concentrated and directly bound to Aβ.

Regional distribution of amyloid-Bri deposition and its association with neurofibrillary degeneration in familial British dementia

, 2001
Familial British dementia (FBD), pathologically characterized by cerebral amyloid angiopathy (CAA), amyloid plaques, and neurofibrillary degeneration, is associated with a stop codon mutation in the BRI gene resulting in the production of an ...

Recent Advances in Photocatalyst‐Driven Protein Labeling and Proximity Mapping

The Chemical Record, EarlyView.
Photocatalyst‐driven protein labeling and proximity mapping have rapidly advanced as powerful strategies for spatiotemporal control in complex biological environments. This review integrates recent developments across single‐electron transfer and energy transfer‐based mechanisms and highlights how catalyst design, reactive intermediates, and diffusion ...

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

Environmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

Amyloid-β acts as a regulator of neurotransmitter release disrupting the interaction between synaptophysin and VAMP2.

, 2012
BACKGROUND: It is becoming increasingly evident that deficits in the cortex and hippocampus at early stages of dementia in Alzheimer's disease (AD) are associated with synaptic damage caused by oligomers of the toxic amyloid-β peptide (Aβ42).
