Molecular ruler mechanism and interfacial catalysis of the integral membrane acyltransferase PatA
(American Association for the Advancement of Science, 2021-10)
[EN]Glycolipids are prominent components of bacterial membranes that play critical roles not only in maintaining the structural integrity of the cell but also in modulating host-pathogen interactions. PatA is an essential ...
FORTIS: a Live-Cell Assay to Monitor AMPA Receptors Using pH-Sensitive Fluorescence Tags
(Nature, 2021-05-27)
The real-time live fluorescent monitoring of surface AMPA receptors (AMPARs) could open new opportunities for drug
discovery and phenotypic screening concerning neuropsychiatric disorders. We have developed FORTIS, a tool ...
Fluorine Labeling of Nanoparticles and In Vivo 19F Magnetic Resonance Imaging
(American Chemical Society, 2021-03-24)
Fluorinated nanoparticles have increasing applications, but they are still challenging to prepare, especially in the case of water-soluble fluorinated nanoparticles. Herein, a fluorine labeling strategy is presented that ...
MERLIN: a novel BRET-based proximity biosensor for studying mitochondria–ER contact sites
(Life Science Alliance, 2020-01)
The contacts between the ER and mitochondria play a key role in cellular functions such as the exchange of lipids and calcium between both organelles, as well as in apoptosis and autophagy signaling. The molecular architecture ...
Four Cholesterol-Recognition Motifs in the Pore-Forming and Translocation Domains of Adenylate Cyclase Toxin Are Essential for Invasion of Eukaryotic Cells and Lysis of Erythrocytes
(MDPI, 2022)
Adenylate Cyclase Toxin (ACT or CyaA) is one of the important virulence factors secreted by Bordetella pertussis, the bacterium causative of whooping cough. ACT debilitates host defenses by production of unregulated levels ...
Conformational Rearrangements Regulating the DNA Repair Protein APE1
(MDPI, 2022)
Apurinic apyrimidinic endonuclease 1 (APE1) is a key enzyme of the Base Excision Repair (BER) pathway, which primarily manages oxidative lesions of DNA. Once the damaged base is removed, APE1 recognises the resulting abasic ...
Incorporation of Antibiotics into Solid Lipid Nanoparticles: A Promising Approach to Reduce Antibiotic Resistance Emergence
(MDPI, 2021-05-10)
Antimicrobial resistance is one of the biggest threats to global health as current antibiotics are becoming useless against resistant infectious pathogens. Consequently, new antimicrobial strategies are urgently required. ...
Single-Aminoacid Discrimination in Proteins with Homogeneous Nanopore Sensors and Neural Networks
(Elsevier, 2021-05-15)
A technology capable of sequencing individual protein molecules would revolutionize our understanding of biological processes. Nanopore technology can analyze single heteropolymer molecules such as DNA by measuring the ...
miR-27b Modulates Insulin Signaling in Hepatocytes by Regulating Insulin Receptor Expression
(MDPI, 2020-11-17)
Insulin resistance (IR) is one of the key contributing factors in the development of type 2 diabetes mellitus (T2DM). However, the molecular mechanisms leading to IR are still unclear. The implication of microRNAs (miRNAs) ...
Focal accumulation of aromaticity at the CDRH3 loop mitigates 4E10 polyreactivity without altering its HIV neutralization profile
(Cell Press, 2021-09-24)
Broadly neutralizing antibodies (bnAbs) against HIV-1 are frequently associated with the presence of autoreactivity/polyreactivity, a property that can limit their use as therapeutic agents. The bnAb 4E10, targeting the ...
