Delivery of small nucleic acids by conjugation to carbohydrates and lipids as novel research and therapeutic tools
(2014-03-12)
Small nucleic acids present a great potential to silence specific genes or inhibit the biological activity of specific proteins. Unfortunately, their poor cellular accessibility presents a big challenge for developing an ...
Reply to Roy and Pucadyil: A gain of function by a GTPase-impaired Drp1
(National Academy of Sciences, 2022-06)
Identification of a New Cholesterol-Binding Site within the IFN-gamma Receptor that is Required for Signal Transduction
(Wiley, 2022)
[EN] The cytokine interferon-gamma (IFN-gamma) is a master regulator of innate and adaptive immunity involved in a broad array of human diseases that range from atherosclerosis to cancer. IFN-gamma exerts it signaling ...
Structure of HIV-1 gp41 with its Membrane Anchors Targeted by Neutralizing Antibodies
(eLife Sciences, 2021-04-19)
The HIV-1 gp120/gp41 trimer undergoes a series of conformational changes in order to catalyze gp41-induced fusion of viral and cellular membranes. Here, we present the crystal structure of gp41 locked in a fusion intermediate ...
Nonlinear material and ionic transport through membrane nanotubes
(Elsevier, 2021-10-01)
Membrane nanotubes (NTs) and their networks play an important role in intracellular membrane transport and intercellular communications. The transport characteristics of the NT lumen resemble those of conventional solid-state ...
Microfluidic chip with pillar array for controlled production and observation of lipid membrane nanotubes
(RSC, 2020-06-29)
Lipid membrane nanotubes (NTs) are a widespread template for in vitro studies of cellular processes happening at high membrane curvature. Traditionally NTs are manufactured one by one, using sophisticated membrane ...
Development of soft and rigid membrane nanotemplates for the mechanistic analysis of Dynamin I action on curved surfaces
(2015-03-26)
En los últimos años se ha ido desvelando el rol activo de la curvaturade membrana en los procesos de reorganización de membranas celulares. Lamayoría de las membranas celulares presentan una cierta curvatura; dichacurvatura ...
Super-Resolution Microscopy to Study Interorganelle Contact Sites
(MDPI, 2022-12-05)
Interorganelle membrane contact sites (MCS) are areas of close vicinity between the membranes of two organelles that are maintained by protein tethers. Recently, a significant research effort has been made to study MCS, ...
Design and Validation of a Process Based on Cationic Niosomes for Gene Delivery into Novel Urine-Derived Mesenchymal Stem Cells
(MDPI, 2021-05-11)
Background: Mesenchymal stem cells (MSCs) are stem cells present in adult tissues. They can be cultured, have great growth capacity, and can differentiate into several cell types. The isolation of urine-derived mesenchymal ...
An Epilepsy-Causing Mutation Leads to Co-Translational Misfolding of the Kv7.2 Channel
(Springer, 2021-05-21)
BACKGROUND: The amino acid sequence of proteins generally carries all the necessary information for acquisition of native conformations, but the vectorial nature of translation can additionally determine the folding outcome. ...
