Membrane properties of ceramide: a fluorescence spectroscopic and microscopic study
(2017-02-24)
Las membranas biológicas son complejas estructuras con una base lipídica y cruciales para lasupervivencia y función de las células. La ceramida es un lípido de membrana con unas característicasfísico-químicas singulares, ...
Regulation of inflammatory processes by ceramide kinase and phosphatidylethanolamine N-methyltransferase in lung cells, adipocytes and liver tissue.
(2019-05-31)
Nowadays, around 60% of the world's population dies due to chronic inflammatory conditions, such as chronic respiratory diseases, obesity, fatty liver disease and cancer. All these pathologies are associated to alterations ...
Mecanismos de reconocimiento y control de tráfico endosomal por el complejo retrómero.
(2018-12-10)
El retrómero es un complejo multiproteíco que participa en múltiples etapas del tráfico vesicular, controlando el reciclaje de cargos presentes en los endosomas a la membrana plasmática, la red Trans-Golgi, así como a ...
Novel mechanisms for regulation of cell survival and migration by ceramide 1-phosphate
(2014-02-07)
Ceramide 1-phosphate is a bioactive sphingolipid that regulates important cell functions, including cell proliferation, apoptosis, migration or inflammation. Cell homeostasis is essential for the normal development of any ...
The Golgi as an Assembly Line to the Autophagosome
(Elsevier, 2020-06)
Autophagy is traditionally depicted as a signaling cascade that culminates in the formation of an autophagosome that degrades cellular cargo. However, recent studies have identified myriad pathways and cellular organelles ...
Photoacoustic effect applied on model membranes and living cells: direct observation with multiphoton excitation microscopy and long-term viability analysis
(Nature, 2020-01-15)
The photoacoustic effect is generated when a variable light interacts with a strongly light-absorbing material. In water, it may produce hot bubbles and shock waves that could affect the integrity of nearby cellular ...
HIV-1 Capture and Transmission by Dendritic Cells: The Role of Viral Glycolipids and the Cellular Receptor Siglec-1
(Public Library Science, 2014-07)
Dendritic cells (DCs) are essential in order to combat invading viruses and trigger antiviral responses. Paradoxically, in the case of HIV-1, DCs might contribute to viral pathogenesis through trans-infection, a mechanism ...
The Myth of The Annular Lipids
(MDPI, 2022-10-22)
In the early 1970s, the existence of a “lipid annulus” stably surrounding the individual intrinsic protein molecules was proposed by several authors. They referred to a number of lipid molecules in slow exchange with the ...
Label-Free Monitoring of Tumor Models by Surface-Enhanced Raman Scattering
(2022-05-13)
El objetivo general de la presente tesis se ha centrado en la monitorización de modelos celulares mediante la técnica de espectroscopia de Raman aumentada en superficies (SERS). Las tecnologías desarrolladas en la tesis ...
Metabolic alterations in urine extracellular vesicles are associated to prostate cancer pathogenesis and progression
(Taylor & Francis, 2018-05-07)
Urine contains extracellular vesicles (EVs) that concentrate molecules and protect them from degradation. Thus, isolation and characterisation of urinary EVs could increase the efficiency of biomarker discovery. We have ...
