¿Por qué es tan difícil fabricar una vacuna contra el SIDA?
Cuando damos una charla sobre la vacuna del sida, la pregunta más frecuente es: ¿cómo ha sido posible fabricar una vacuna frente a la covid-19 en menos de un año y que después de cuatro décadas no tengamos aún ninguna para el VIH? Además de sentirnos algo torpes, intentamos explicar que no pueden c...
Title: p38δ Regulates IL6 Expression Modulating ERK Phosphorylation in Preadipocytes.
IL6 is an essential cytokine in metabolism regulation and for intercommunication among different organs and tissues. IL6 produced by different tissues has different functions and therefore it is very important to understand the mechanism of its expression in adipose tissue. In this work we demonstr...
Dual-labeled nanoparticles based on small extracellular vesicles for tumor detection.
Small extracellular vesicles (sEVs) are emerging natural nanoplatforms in cancer diagnosis and therapy, through the incorporation of signal components or drugs in their structure. However, for their translation into the clinical field, there is still a lack of tools that enable a deeper understandi...
Jornada informativa de presentación de la Acción Estratégica en Salud del ISCIII: así es la AES 2023
La Acción Estratégica en Salud (AES) del Instituto de Salud Carlos III (ISCIII), cuya autorización para la convocatoria 2023 aprobó el Consejo de Ministros la pasada semana, se ha presentado este martes con una jornada informativa que ha tenido lugar en el Instituto de Investigación Biomédica de Má...
ABLE: Automated Brain Lines Extraction Based on Laplacian Surface Collapse.
The archetypical folded shape of the human cortex has been a long-standing topic for neuroscientific research. Nevertheless, the accurate neuroanatomical segmentation of sulci remains a challenge. Part of the problem is the uncertainty of where a sulcus transitions into a gyrus and vice versa. This...
Influence of diabetes on sacubitril/valsartan titration and clinical outcomes in patients hospitalized for heart failure.
Diabetes mellitus is associated with worse outcomes and lower attainment of disease-modifying therapies in patients with heart failure with reduced ejection fraction (HFrEF). This post hoc analysis of TRANSITION compared the patterns of tolerability and uptitration of sacubitril/valsartan in patien...
Multiomic Data Integration in the Analysis of Drought-Responsive Mechanisms in Quercus ilex Seedlings.
The integrated analysis of different omic layers can provide new knowledge not provided by their individual analysis. This approach is also necessary to validate data and reveal post-transcriptional and post-translational mechanisms of gene expression regulation. In this work, we validated the poss...
Extracellular vesicles from Listeria monocytogenes-infected dendritic cells alert the innate immune response.
Communication through cell-cell contacts and extracellular vesicles (EVs) enables immune cells to coordinate their responses against diverse types of pathogens. The function exerted by EVs in this context depends on the proteins and nucleic acids loaded into EVs, which elicit specific responses inv...
Retinal Pigment Epithelium-Secreted VEGF-A Induces Alpha-2-Macroglobulin Expression in Endothelial Cells.
Alpha-2-macroglobulin (A2M) is a protease inhibitor that regulates extracellular matrix (ECM) stability and turnover. Here, we show that A2M is expressed by endothelial cells (ECs) from human eye choroid. We demonstrate that retinal pigment epithelium (RPE)-conditioned medium induces A2M expression...
Clinical Risk Score to Predict Pathogenic Genotypes in Patients With Dilated Cardiomyopathy.
Although genotyping allows family screening and influences risk-stratification in patients with nonischemic dilated cardiomyopathy (DCM) or isolated left ventricular systolic dysfunction (LVSD), its result is negative in a significant number of patients, limiting its widespread adoption.
This stud...
Mitochondrial dynamics maintain muscle stem cell regenerative competence throughout adult life by regulating metabolism and mitophagy.
Skeletal muscle regeneration depends on the correct expansion of resident quiescent stem cells (satellite cells), a process that becomes less efficient with aging. Here, we show that mitochondrial dynamics are essential for the successful regenerative capacity of satellite cells. The loss of mitoch...
Asociación entre tiempo en actividad física, sedentarismo y síndrome metabólico en el adulto mayor
El síndrome metabólico es especialmente prevalente en adultos mayores de 60 años, lo que aumenta el riesgo de enfermedad cardiovascular y de mortalidad disminuyendo en 5 años la tasa de supervivencia. El objetivo de este estudio fue examinar, teóricamente, cómo la reasignación del tiempo entre la i...
Total urinary polyphenols and ideal cardiovascular health metrics in Spanish adolescents enrolled in the SI Program: a cross-sectional study.
To study the relationship between urinary total polyphenol excretion (TPE) in adolescents and ideal cardiovascular (CVH) metrics. 1151 adolescents aged 12.04 (0.46) years participating in the SI! Program for Secondary Schools were selected based on the availability of urine samples and information ...
Frequency of hereditary transthyretin amyloidosis among elderly patients with transthyretin cardiomyopathy.
Transthyretin amyloid cardiomyopathy (ATTR-CM) is increasingly recognized as a cause of heart failure in the elderly. Although wild-type transthyretin amyloidosis is the most frequent form of ATTR-CM found in the elderly, hereditary transthyretin amyloidosis (ATTRv) can also occur. We sought to det...
Natural killer (NK) cell-derived extracellular-vesicle shuttled microRNAs control T cell responses.
Natural killer (NK) cells recognize and kill target cells undergoing different types of stress. NK cells are also capable of modulating immune responses. In particular, they regulate T cell functions. Small RNA next-generation sequencing of resting and activated human NK cells and their secreted ex...
Using Machine Learning to Predict Obesity Based on Genome-Wide and Epigenome-Wide Gene-Gene and Gene-Diet Interactions.
Obesity is associated with many chronic diseases that impair healthy aging and is governed by genetic, epigenetic, and environmental factors and their complex interactions. This study aimed to develop a model that predicts an individual's risk of obesity by better characterizing these complex relat...
Variant pathogenic prediction by locus variability: the importance of the current picture of evolution.
Accurate detection of pathogenic single nucleotide variants (SNVs) is a key challenge in whole exome and whole genome sequencing studies. To date, several in silico tools have been developed to predict deleterious variants from this type of data. However, these tools have limited power to detect ne...
Feto-maternal microchimerism: Memories from pregnancy.
There is a bidirectional transplacental cell trafficking between mother and fetus during pregnancy in placental mammals. The presence and persistence of fetal cells in maternal tissues are known as fetal microchimerism (FMc). FMc has high multilineage potential with a great ability to differentiate...
El centro Nacional de Sanidad Ambiental crea una nueva unidad de evaluación de riesgos
El Centro Nacional de Sanidad Ambiental (CNSA) del ISCIII ha creado la Unidad Horizontal de Evaluación de Riesgos, que reforzará la labor del centro en el estudio de los posibles efectos sobre la salud de las personas que puedan derivarse de la exposición ambiental a contaminantes. La Unidad, que ...
El desequilibrio en la actividad de las enzimas que compactan el ADN causa la muerte de las bacterias
Un equipo de investigadoras del Instituto de Salud Carlos III (ISCIII) ha publicado un artículo en la revista Frontiers in Microbiology que revela que el equilibrio de la actividad de las dos principales enzimas que permiten la compactación del ADN de las bacterias es imprescindible para que las cé...
