Exosome‐mediated gut–brain axis signaling in neurodegenerative diseases: Mechanisms, experimental evidence, and therapeutic perspectives—A narrative review

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The gut–brain axis is a bidirectional communication network between the intestines and brain, mediated by gut microbiota and exosomes, that regulates neuroinflammation, protein aggregation, and neuronal health processes central to neurodegenerative diseases.

Animal models in molecular biology research: Challenges, ethical imperatives, and the path to human‐relevant translation

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The graphical abstract shows how molecular biology research has shifted from using traditional animal models toward using methods that are more relevant to humans. It points out the main problems, differences between species, difficulty in reproducing results, moral issues, and lack of infrastructure that make translational accuracy harder to achieve ...

Water‐Mediated Phosphoryl Wires Stabilize Pathological Tau Fibrils

open access: yesAngewandte Chemie, EarlyView.
Extended 1D phosphoryl “wires” stabilize in‐register amyloid tau fibrils, as demonstrated by multiple‐quantum spin‐counting NMR, TEM, and MD simulations, using fibrils of tau peptide jR2R3‐P301L (tau295–313) with phosphorylation at S305 or Y310. ABSTRACT Hyperphosphorylation of tau is a hallmark of tauopathies, with specific phosphorylation sites ...

β-Amyloid peptides induce mitochondrial dysfunction and oxidative stress in astrocytes and death of neurons through activation of NADPH oxidase

open access: yes, 2004
β-Amyloid (βA) peptide is strongly implicated in the neurodegeneration underlying Alzheimer's disease, but the mechanisms of neurotoxicity remain controversial. This study establishes a central role for oxidative stress by the activation of NADPH oxidase

Biochemical and Immunohistochemical Associations of TDP‐43 and Cryptic RNA With Hippocampal and Amygdala Volumetrics in Alzheimer's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective Immunohistochemically (IHC) measured transactive response DNA‐binding protein 43 (TDP‐43) inclusions are observed in Alzheimer's disease (AD) and are associated with medial temporal lobe atrophy. Accumulation of cryptic exons occurs in AD in response to TDP‐43 pathology.

Malignant progression of liver cancer progenitors requires lysine acetyltransferase 7–acetylated and cytoplasm‐translocated G protein GαS

open access: yesHepatology, EarlyView., 2022
KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.

Total Chemical Synthesis of Interleukin‐15 and Interleukin‐2: Taming Protein Hydrophobicity and Aggregation by a Versatile Solubilizing Strategy

open access: yesAngewandte Chemie, EarlyView.
A reducible solubilizing tag strategy (RST‐2.0) enables the synthesis, purification and ligation of difficult peptides while being readily removable just during folding, which overcomes the common challenges from protein hydrophobicity and aggregation. With this method, we achieved the first total synthesis of native and N‐glycosylated IL‐15 as well as

Bri1 gene-related dementias; A morphological and biochemical study.

open access: yes, 2006
Aspects of the neurodegenerative mechanism in AD remain unknown therefore studies on alternative models of cerebral amyloidosis, such as familial British dementia (FBD) and familial Danish dementia (FDD) may contribute to a better understanding of the ...

Alzheimer's Disease Co‐Pathology and Cognitive Impairment in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Neurology, EarlyView.
Objectives Amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD) share neuropathological features, including tau, amyloid, and TDP‐43 pathology. This study investigated whether AD‐related pathological changes are associated with cognitive impairment ALS. Methods Cerebrospinal fluid (CSF total‐tau, phosphorylated‐tau, beta‐amyloid) and plasma

A nationwide assessment of hepatocellular adenoma resection: Indications and pathological discordance

open access: yesHepatology Communications, EarlyView., 2022
Abstract Hepatocellular adenomas (HCAs) are benign liver tumors associated with bleeding or malignant transformation. Data on the indication for surgery are scarce. We analyzed indications and outcome of patients operated for HCAs < 50 mm compared to HCAs ≥ 50 mm. Changes in final postoperative diagnosis were assessed.
