Inflammation in multiple sclerosis induces a specific reactive astrocyte state driving non-cell-autonomous neuronal damage
An in‐depth understanding of the neurodegenerative component of multiple sclerosis (MS) is crucial for the design of therapeutic approaches that may stop disease progression. Astrocytes have emerged as key contributors to ...
Translating cell therapies for neurodegenerative diseases: Huntington's disease as a model disorder.
There has been substantial progress in the development of regenerative medicine strategies for central nervous system disorders over the last decade, with progression to early clinical studies for some conditions. However, ...
Inflammatory neuronal loss in the substantia nigra induced by systemic lipopolysaccharide is prevented by knockout of the P2Y 6 receptor in mice
Inflammation may contribute to multiple brain pathologies. One cause of inflammation is lipopolysaccharide/endotoxin (LPS), the levels of which are elevated in blood and/or brain during bacterial infections, gut dysfunction ...
The antilipolytic effect of insulin and epidermal growth factor in rat adipocytes are mediated by different mechanisms
Epidermal growth factor (EGF) and insulin induced similar effects in isolated rat adipocytes. To determine whether EGF and insulin produced similar effects through the same mechanisms, we focused on lipolysis. Insulin ...
Fine-mapping of prostate cancer susceptibility loci in a large meta-analysis identifies candidate causal variants.
Prostate cancer is a polygenic disease with a large heritable component. A number of common, low-penetrance prostate cancer risk loci have been identified through GWAS. Here we apply the Bayesian multivariate variable ...
Optogenetic generation of leader cells reveals a force-velocity relation for collective cell migration
During development, wound healing and cancer invasion, migrating cell clusters feature highly protrusive leader cells at their front. Leader cells are thought to pull and direct their cohort of followers, but whether their ...
CD5 and CD6 as immunoregulatory biomarkers in non-small cell lung cancer
Background: The study of immune surveillance in the tumour microenvironment is leading to the development of new biomarkers and therapies. The present research focuses on the expression of CD5 and CD6 - two lymphocyte ...
Characterization of Blood Immune Cells in Patients With Decompensated Cirrhosis Including ACLF
Background and Aims: Patients with cirrhosis and acute-on-chronic liver failure (ACLF) have immunosuppression, indicated by an increase in circulating immune-deficient monocytes. The aim of this study was to investigate ...
Sleep Apnoea Adverse Effects on Cancer: True, False, or Too Many Confounders?
: Obstructive sleep apnoea (OSA) is a prevalent disorder associated with increased cardiovascular, metabolic and neurocognitive morbidity. Recently, an increasing number of basic, clinical and epidemiological reports have ...
Molecular clutch drives cell response to surface viscosity
Cell response to matrix rigidity has been explained by the mechanical properties of the actin-talin-integrin-fibronectin clutch. Here the molecular clutch model is extended to account for cell interactions with purely ...
The G-protein coupled receptor ChemR23 determines smooth muscle cell phenotypic switching to enhance high phosphate-induced vascular calcification
AIMS: Vascular calcification, a marker of increased cardiovascular risk, is an active process orchestrated by smooth muscle cells. Observational studies indicate that omega-3 fatty acids protect against vascular calcification, ...
Germline variation at 8q24 and prostate cancer risk in men of European ancestry
Chromosome 8q24 is a susceptibility locus for multiple cancers, including prostate cancer. Here we combine genetic data across the 8q24 susceptibility region from 71,535 prostate cancer cases and 52,935 controls of European ...
TRPM7 controls mesenchymal features of breast cancer cells by tensional regulation of SOX4
Mechanically induced signaling pathways are important drivers of tumor progression. However, if and how mechanical signals affect metastasis or therapy response remains poorly understood. We previously found that the ...
Integrating external and internal load for monitoring fitness and fatigue status in standard microcycles in elite rink hockey
The aims of this study were 3-fold: firstly, to present an integrative approach to external and internal load dynamics for monitoring fitness and fatigue status of specific in-court rink hockey training sessions in a ...
Diazoxide enhances excitotoxicity-induced neurogenesis and attenuates neurodegeneration in the rat non-neurogenic hippocampus
Diazoxide, a well-known mitochondrial KATP channel opener with neuroprotective effects, has been proposed for the effective and safe treatment of neuroinflammation. To test whether diazoxide affects the neurogenesis ...
El reto educativo de El buen quehacer del médico
In March 2014 the General Council of Official Medical Associations (CGCOM) published a document entitled The Good Physician housework, which can be accessed at www.fundacioneducacionmedica.org. The document was drawn up ...
Akt-mediated FoxO1 inhibition is required for liver regeneration
Understanding the hepatic regenerative process has clinical interest as the effectiveness of many treatments for chronic liver diseases is conditioned by efficient liver regeneration. Experimental evidence points to the ...
Mechanisms of immunity in acutely decompensated cirrhosis and acute-on-chronic liver failure
The identification of systemic inflammation (SI) as a central player in the orchestration of acute-on-chronic liver failure (ACLF) has opened new avenues for the understanding of the pathophysiological mechanisms underlying ...
Oxidized albumin triggers a cytokine storm in leukocytes through p38 MAP kinase: role in systemic inflammation in decompensated cirrhosis.
Decompensated cirrhosis is characterized by exuberant systemic inflammation. Although the inducers of this feature remain unknown, the presence of circulating forms of oxidized albumin, namely human nonmercaptalbumin 1 ...
Reduced fractalkine levels lead to striatal synaptic plasticity deficits in Huntington's disease
Huntington's disease (HD) is an inherited neurodegenerative disorder in which the striatum is the most affected brain region. Although a chronic inflammatory microglial reaction that amplifies disease progression has been ...
