Receptor for advanced glycation end products is subjected to protein ectodomain shedding by metalloproteinases.
2008
The receptor for advanced glycation end products (RAGE) is a 55-kDa type I membrane glycoprotein of the immunoglobulin superfamily. Ligand-induced up-regulation of RAGE is involved in various pathophysiological processes, including late diabetic complications and Alzheimer disease. Application of recombinant soluble RAGE has been shown to block RAGE-mediated pathophysiological conditions. After expression of full-length RAGE in HEK cells we identified a 48-kDa soluble RAGE form (sRAGE) in the culture medium. This variant of RAGE is smaller than a 51-kDa soluble version derived from alternative splicing. The release of sRAGE can be induced by the phorbol ester PMA and the calcium ionophore c…

La actividad física previene numerosas patologías y mejora muchos rasgos fisiopatológicos en diferentes enfermedades. El ejercicio ha sido asociado clásicamente con beneficios en desórdenes musculares y metabólicos. Sin embargo, los efectos del ejercicio en la función cerebral, especialidad conocida como “Neurobiología del ejercicio”, han cobrado gran importancia en los últimos años. Los efectos beneficiosos del ejercicio físico han sido establecidos en muchas enfermedades tales como la enfermedad de Alzheimer, el Parkinson, la esclerosis lateral amiotrófica, la esquizofrenia, el trastorno bipolar y los trastornos depresivos, entre otros. Estos hallazgos han llevado a utilizar el ejercicio …

Characterization of Epileptic Spiking Associated With Brain Amyloidosis in APP/PS1 Mice
2019
Epileptic activity without visible convulsions is common in Alzheimer’s disease (AD) and may contribute adversely to the disease progress and symptoms. Transgenic mice with amyloid plaque pathology also display epileptic seizures, but those are too infrequent to assess the effect of anti-epileptic treatments. Besides spontaneous seizures, these mice also display frequent epileptic spiking in epidural EEG recordings, and these have provided a means to test potential drug treatment to AD-related epilepsy. However, the origin of EEG spikes in transgenic AD model mice has remained elusive, which makes it difficult to relate electrophysiology with underlying pathology at the cellular and molecul…

Classification of healthy, Alzheimer and Parkinson populations with a multi-branch neural network
2022
Signal processing, for delimitation of the target events and parametrization, is usually required when instrumented assessment is conducted to determine an individual’s functional status. However, these procedures may rule out relevant information obtained by sensors. To prevent this, the use of models based on neural networks that automatically extract relevant features from the raw signal may improve the characterization of the functional status. Thus, the aim of the study was to determine the classification accuracy of a multi-head convolutional layered neural network (CNN) using a simple functional mobility test in people with different conditions. The raw data from an inertial sensor e…
Biodistribution of Insulin-Nanogels in Mouse: A Preliminary Study for the Treatment of Alzheimer's Disease
2017
A growing body of evidence shows that Insulin, Insulin Receptor (IR) and IR signaling are involved in brain cognitive functions and their dysfunction is implicated in Alzheimer's disease (AD) neurodegeneration. Thus, administration of insulin could be a strategy for AD treatment. For this aim we have designed, synthesized and characterized a nanogel system (NG) that has been conjugated to insulin molecules (NG-In) to deliver the protein into the brain, as a tool for the development of a new therapy against AD. In our preclinical study in mice, intraperitoneal injection of fluorescent-labeled NG has allowed to determine the biodistribution of NG vs time in the whole body and its clearance th…

Ajokyvyn arviointi MoCA-menetelmällä Alzheimerin taudin varhaisvaiheessa
2019
Vertaisarvioitu Lähtökohdat Tutkimme Montreal Cognitive Assessment (MoCA) -menetelmän soveltuvuutta varhaista Alzheimerin tautia sairastavien potilaiden ajokyvyn arviointiin. Selvitimme myös menetelmän herkkyyttä tunnistaa kognitiomuutoksia. Menetelmät Tutkimus sisälsi haastattelun, kognitiivisen arvioinnin (MoCA), ajon simulaattorilla ja oman ajamisen arvioinnin. Siihen osallistui 7 potilasta ja 17 tervettä ikätoveria. Tulokset Potilaat suoriutuivat verrokkeja heikommin MoCA-testissä ja simulaattoriajossa. Arvio omasta suoriutumisesta ajossa oli heillä merkitsevästi parempi kuin verrokeilla. Potilaat saivat testipisteitä keskimäärin 18,6 ja verrokit 27,4. Simulaattoriajossa potilaat tekivä…
