Competitive Mirror Image Phage Display Derived Peptide Modulates Amyloid Beta Aggregation and Toxicity. [PDF]

PLoS ONE, 2016
Alzheimer´s disease is the most prominent type of dementia and currently no causative treatment is available. According to recent studies, oligomeric species of the amyloid beta (Aβ) peptide appear to be the most toxic Aβ assemblies. Aβ monomers, however,

Effect of Surfaces on Amyloid Fibril Formation [PDF]

arXiv, 2017
Using atomic force microscopy (AFM) we investigated the interaction of amyloid beta (Ab) (1 42) peptide with chemically modified surfaces in order to better understand the mechanism of amyloid toxicity, which involves interaction of amyloid with cell membrane surfaces.

Changes in lipid membranes may trigger amyloid toxicity in Alzheimer's disease [PDF]

, 2017
Amyloid beta peptides (A\b{eta}), implicated in Alzheimers disease (AD), interact with the cellular membrane and induce amyloid toxicity. The composition of cellular membranes changes in aging and AD. We designed multi component lipid models to mimic healthy and diseased states of the neuronal membrane. Using atomic force microscopy (AFM), Kelvin probe

Neurodegeneration: Potential Causes, Prevention, and Future Treatment Options [PDF]

, 2011
Here I advance a hypothesis that neurodegeneration is a natural process associated with aging due to the loss of genetic redundancy following a mathematical model R(t) = R0(1-αe(βC+γI+δEt)t), where the calorie intake (C) and ...

Diplazium esculentum (Retz.) Sw. reduces BACE-1 activities and amyloid peptides accumulation in Drosophila models of Alzheimer’s disease

Scientific Reports, 2021
Alzheimer’s disease (AD), one type of dementia, is a complex disease affecting people globally with limited drug treatment. Thus, natural products are currently of interest as promising candidates because of their cost-effectiveness and multi-target ...

AhR‐Dependent Induction of β‐Defensin 1 in Colonic Epithelial Cells Regulates Cross‐Talk between Gut Microbiota and Immune Response Leading to Attenuation of Colitis

Advanced Science, EarlyView.
This study identifies a key signaling pathway involving the environmental sensor AhR and antimicrobial peptides, such as BD‐1, in the regulation of intestinal homeostasis. It highlights the role of BD‐1 in regulating gut microbiota and the intestinal immune response.

The Budapest Amyloid Predictor and its Applications [PDF]

arXiv, 2020
The amyloid state of proteins is widely studied with relevancy in neurology, biochemistry, and biotechnology. In contrast with amorphous aggregation, the amyloid state has a well-defined structure, consisting of parallel and anti-parallel $\beta$-sheets in a periodically repeated formation.

Supramolecular Gels as Active Tools for Reaction Engineering

Angewandte Chemie, EarlyView.
The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Microglia and amyloid precursor protein coordinate control of transient Candida cerebritis with memory deficits

Nature Communications, 2019
The potential links between infections and neurodegenerative disorders are unclear. Here, Wu et al. present a mouse model of low-grade candidemia characterized by highly localized cerebritis, accumulation of amyloid precursor protein and beta peptides ...
