Super-Resolution Microscopy Using a Bioorthogonal-Based Cholesterol Probe Provides Unprecedented Capabilities for Imaging Nanoscale Lipid Heterogeneity in Living Cells
(Wiley, 2021-09)
Despite more than 20 years of work since the lipid raft concept was proposed, the existence of these nanostructures remains highly controversial due to the lack of noninvasive methods to investigate their native nanorganization ...
Using a Simple Cellular Assay to Map NES Motifs in Cancer-Related Proteins, Gain Insight into CRM1-Mediated NES Export, and Search for NES-Harboring Micropeptides
(MDPI, 2020-09-01)
The nuclear export receptor CRM1 (XPO1) recognizes and binds specific sequence motifs termed nuclear export signals (NESs) in cargo proteins. About 200 NES motifs have been identified, but over a thousand human proteins ...
Role of lipids in HIV-1 pathogenesis. Implications in viral infectivity and development of antiretroviral drugs.
(2019-05-17)
En esta tesis doctoral se ha estudiado el papel de los lípidos en distintos pasos del ciclo infectivo del VIH-1, y su potencial uso para el desarrollo de agentes antiretrovirales. Los resultados de este trabajo demuestran ...
Development of functionalized reconstituted HDL as a novel anti-atherosclerotic tool
(2022-02-25)
El objetivo de mi tesis se centra en el desarrollo de partículas recombinantes que imitan las pre-ßHDL naturales, para su utilización como medio de transporte de microRNAs. Estas partículas serían utilizadas para tratar ...
Calcium effect on dynamics and stability of KV7.2 channel
(2020-09-29)
La familia Kv7 controla la excitación celular en diferentes tejidos, por lo que es importante investigar su fisiología y fisiopatología. Se relaciona con enfermedades como la epilepsia, encefalopatías, arritmias, diabetes ...
Engineering pan–HIV-1 neutralization potency through multispecific antibody avidity
(National Academy of Sciences of the United States of America, 2022-01-25)
Deep mining of B cell repertoires of HIV-1-infected individuals has resulted in the isolation of dozens of HIV-1 broadly neutralizing antibodies (bNAbs). Yet, it remains uncertain whether any such bNAbs alone are sufficiently ...
Fluorescence Microscopy of the HIV-1 Envelope
(MDPI, 2020-03-21)
Human immunodeficiency virus (HIV) infection constitutes a major health and social issue worldwide. HIV infects cells by fusing its envelope with the target cell plasma membrane. This process is mediated by the viral Env ...
Promotion of membrane interactions as a pathway for HIV antibody optimization
(2021-01-15)
GIBak Env fusio glukoproteina erabiltzen du CD4 hartzailea adierazten duten zelulak infektatzeko. Immunitate sistemari eskuragarri dagoen antigeno bakarra izan arren, Env-ek honi ihes egiteko dituen mekanismoek erantzun ...
Structural insights into the ability of nucleoplasmin to assemble and chaperone histone octamers for DNA deposition
(Nature Publishing Group, 2019-07-01)
Nucleoplasmin (NP) is a pentameric histone chaperone that regulates the condensation state of chromatin in different cellular processes. We focus here on the interaction of NP with the histone octamer, showing that NP could ...
Lipid-Assisted Polymerization of Nucleotides
(MDPI, 2019-11-05)
In addition to being one of the proponents of the "Lipid World hypothesis", David Deamer, together with other colleagues, pioneered studies involving formation of RNA-like oligomers from their 'non-activated', prebiotically ...
