Prion protein interactome: identifying novel targets in slowly and rapidly progressive forms of alzheimer's disease
Rapidly progressive Alzheimer's disease (rpAD) is a variant of AD distinguished by a rapid decline in cognition and short disease duration from onset to death. While attempts to identify rpAD based on biomarker profile ...
Dissecting the conserved NPxxY motif of the M<sub>3</sub> muscarinic acetylcholine receptor: critical role of Asp-7.49 for receptor signaling and multiprotein complex formation
Acetylcholine challenge produces M-3 muscarinic acetylcholine receptor activation and accessory/scaffold proteins recruitment into a signalsome complex. The dynamics of such a complex is not well understood but a conserved ...
Toxins Secreted by Bacillus Isolated from Lung Adenocarcinomas Favor the Penetration of Toxic Substances
The aim was to explore the eventual role of bacteria in the induction of lung cancer by smoking habits. Viable bacteria closely related to the genus Bacillus were detected at high frequencies in lung-cancer biopsies. ...
Purine-related metabolites and their converting enzymes are altered in frontal; parietal; and temporal cortex at early stages of Alzheimer's disease pathology
Adenosine, hypoxanthine, xanthine, guanosine, and inosine levels were assessed by HPLC, and the activity of related enzymes 5'-nucleotidase (5'-NT), adenosine deaminase (ADA), and purine nucleoside phosphorylase (PNP) ...
BetaII-tubulin and phospho-tau aggregates in alzheimer's disease and pick's disease
The expression of betaI-, betaII- and betaIII-tubulin isotypes was examined by immunohistochemistry in the entorhinal and transentorhinal cortices, hippocampus and dentate gyrus in normal human brains and in cases with ...
Presynaptic control of striatal glutamatergic neurotransmission by adenosine A1-A2A receptor heteromers
The functional role of heteromers of G-protein-coupled receptors is a matter of debate. In the present study, we demonstrate that heteromerization of adenosine A1 receptors (A1Rs) and A2A receptors (A2ARs) allows adenosine ...
Inhibitory Control of Basolateral Amygdalar Transmission to the Prefrontal Cortex by Local Corticotrophin Type 2 Receptor
Background: Basolateral amygdalar projections to the prefrontal cortex play a key role in modulating behavioral responses to stress stimuli. Among the different neuromodulators known to impact basolateral amygdalar-prefrontal ...
Crtc1 activates a transcriptional program deregulated at early Alzheimer's disease-related stages
Cognitive decline is associated with gene expression changes in the brain, but the transcriptional mechanisms underlying memory impairments in cognitive disorders, such as Alzheimer's disease (AD), are largely unknown. ...
Design, synthesis and characterization of a new series of fluorescent metabotropic glutamate receptor type 5 negative allosteric modulators
In recent years, new drug discovery approaches based on novel pharmacological concepts have emerged. Allosteric modulators, for example, target receptors at sites other than the orthosteric binding sites and can modulate ...
Abnormal expression and distribution of MMP2 at initial stages of Alzheimer's disease-related pathology
Previous studies have shown that metalloproteinases (MMPs) participate in the clearance of amyloid-β (Aβ) in Alzheimer's disease (AD); MMP2 and MMP3 cleave soluble Aβ, and both MMP9 and MT1-MMP are able to degrade soluble ...
Espolón escleral y músculo ciliar
Espolón escleral y músculo ciliar: el estudio con el microscopio óptico y de barrido de preparaciones de ojos de Herbívoros, Primates, Gorila y Humanos, nos ha permitido confirmar que todas las estructuras del ángulo ...
Neuroinflammation in the dorsolateral prefrontal cortex in elderly chronic schizophrenia
Cognitive deterioration and symptom progression occur in schizophrenia over the course of the disorder. A dysfunction of the immune system/neuroinflammatory pathways has been linked to schizophrenia (SZ). These altered ...
Available evidence and outcome of off-label use of rituximab in clinical practice
Purpose: To analyze the therapeutic indications for off-label use of rituximab, the available evidence for its use, the outcomes, and the cost. Methods: This was a retrospective analysis of patients treated with rituximab ...
Tauroursodeoxycholic bile acid arrests axonal degeneration by inhibiting the unfolded protein response in X-linked adrenoleukodystrophy
The activation of the highly conserved unfolded protein response (UPR) is prominent in the pathogenesis of the most prevalent neurodegenerative disorders, such as Alzheimer's disease (AD), Parkinson's disease (PD) and ...
Ligand with Two Modes of Interaction with the Dopamine D2 Receptor–An Induced-Fit Mechanism of Insurmountable Antagonism
A solid understanding of the mechanisms governing ligand binding is crucial for rational design of therapeutics targeting the dopamine D2 receptor (D2R). Here, we use G protein-coupled inward rectifier potassium (GIRK) ...
Redox balance and carbonylated protein in limb muscles and heart of cachectic rats
In fast- and slow-twitch limb and heart muscles of cachectic rats, redox balance and muscle structure were explored. The nature of the oxidatively modified proteins also was identified in these muscles. Reactive carbonyls, ...
Lactic acidosis associated with metformin in patients with moderate to severe chronic kidney disease: study protocol for a multicenter population-based case-control study using health databases.
Background: The use of metformin in patients with type 2 diabetes mellitus has been associated with lactic acidosis. However, the information available in patients with moderate-severe chronic kidney disease is scarce. ...
Disclosing bias in bisulfite assay: MethPrimers underestimate high DNA methylation
Discordant results obtained in bisulfite assays using MethPrimers (PCR primers designed using MethPrimer software or assuming that non-CpGs cytosines are non methylated) versus primers insensitive to cytosine methylation ...
Therapeutic strategies involving survivin inhibition in cancer
Survivin is a small protein that belongs to the inhibitor of apoptosis protein family. It is abundantly expressed in tumors compared with adult differentiated tissues, being associated with poor prognosis in many human ...
Enhancing glycolysis attenuates Parkinson's disease progression in models and clinical databases
Parkinson's disease (PD) is a common neurodegenerative disease that lacks therapies to prevent progressive neurodegeneration. Impaired energy metabolism and reduced ATP levels are common features of PD. Previous studies ...
