Alzheimer’s Disease as a Membrane Disorder: Spatial Cross-Talk Among Beta-Amyloid Peptides, Nicotinic Acetylcholine Receptors and Lipid Rafts [PDF]

, 2019
Biological membranes show lateral and transverse asymmetric lipid distribution. Cholesterol (Chol) localizes in both hemilayers, but in the external one it is mostly condensed in lipid-ordered microdomains (raft domains), together with saturated ...

Phosphate‐ and pH‐dependent self‐assembly of recombinant spider silk proteins

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The process of molecular self‐assembly is an omnipresent mechanism in nature to generate a variety of efficient and functional hierarchical architectures, and inspires tailored material design and development. Thereby, self‐assembly is based on a controlled interplay and association of monomers into highly ordered structures triggered by ...

P2Y2 Nucleotide Receptors Enhance α-Secretase-dependent Amyloid Precursor Protein Processing [PDF]

Journal of Biological Chemistry, 2005
The amyloid precursor protein (APP) is proteolytically processed by beta- and gamma-secretases to release amyloid beta, the main component in senile plaques found in the brains of patients with Alzheimer disease. Alternatively, APP can be cleaved within the amyloid beta domain by alpha-secretase releasing the non-amyloidogenic product sAPP alpha, which

Psychobiotics and the microbiota–gut–brain axis: Emerging paradigms in mental health modulation

Experimental Physiology, Volume 111, Issue 5, Page 2449-2463, 1 May 2026.
Abstract The global rise in mental health conditions has prompted interest in interventions that act beyond conventional psychopharmacology. Psychobiotics, broadly understood as live microorganisms or microbe‐derived products that interact with the microbiota–gut–brain axis, have been suggested to exert neuroactive effects through neural, immune ...

Different types of γ-secretes complexes and their effect on substrate processing [PDF]

, 2012
The γ-secretase complex is a transmembrane aspartyl protease that generates the Alzheimer disease (AD) related amyloid β-peptide (Aβ) from the amyloid precursor protein (APP). The γ- secretase complex cleaves APP at two different sites (γ- and ε-sites)

Biodegradable Carbonate Nanogels Loaded with Anti MFAP‐5 siRNA for Anti‐stromal Therapy of Hepatocellular Carcinoma

Advanced Science, Volume 13, Issue 21, 13 April 2026.
Polycarbonate nanogels enable lipid‐free delivery of anti‐MFAP‐5 siRNA into cancer‐associated fibroblasts (CAF) in hepatocellular carcinoma. In a cirrhotic murine model, this approach silences MFAP‐5, reduces fibroblast activation, and suppresses tumor growth by inhibiting NOTCH/Hes1‐driven angiogenesis. CAF‐targeted MFAP‐5 RNAi and conserved signaling

Synapse-Associated Protein-97 Mediates α-Secretase ADAM10 Trafficking and Promotes Its Activity [PDF]

The Journal of Neuroscience, 2007
Alzheimer's disease (AD) is a chronic neurodegenerative disorder caused by a combination of events impairing normal neuronal function. Here we found a molecular bridge between key elements of primary and secondary pathogenic events in AD, namely the elements of the amyloid cascade and synaptic dysfunction associated with the ...

The secreted APP ectodomain sAPPα, but not sAPPβ, protects neurons against Aβ oligomer-induced dendritic spine loss and increased tau phosphorylation

Molecular Brain, 2019
Aim The amyloid precursor protein (APP) is endoproteolytically processed to generate either the neurotoxic beta-amyloid peptide (Aβ) or the secreted ectodomain APP alpha (sAPPα).

Hypoxic regulation of ion channel function and expression [PDF]

, 2002
Acute hypoxia regulates the activity of specific ion channels in a rapid and reversible manner. Such effects underlie appropriate cellular responses to hypoxia which are designed to initiate cardiorespiratory reflexes and contribute importantly to other ...

Intracellular protein GBF1 displays significant associations with amyloid pathology in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Despite the identification of familial Alzheimer's disease (FAD) genes and neuropathological alterations, AD displays complex genetic heterogeneity and molecular pathogenesis that warrant further investigation. GBF1 (Golgi brefeldin A resistant guanine nucleotide exchange factor 1) regulates protein trafficking, and genetic ...
