Ligand Effects in Low-Valent Co(I) Clathrochelate Complexes

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Ophélie Marie Planes

Clathrochelate complexes of cobalt are known in the oxidation states I, II, and III. Low-valent Co(I) complexes are highly reactive compounds, and there is only limited knowledge about their structures in the solid state. Herein, we describe the crystallog ...

Towards artificial mechanosensing

Aleksandra Radenovic, Sanjin Marion

Carbon nanotubes with single-digit diameter embedded in a solid artificial membrane show pressure-sensitive ionic conductance that is similar to the mechanically activated currents of biological ion channels. ...

Ligand Binding to the Collagen VI Receptor Triggers a Talin-to-RhoA Switch that Regulates Receptor Endocytosis

Françoise Gisou van der Goot Grunberg, Matteo Dal Peraro, Laurence Gouzi Abrami, Luciano Andres Abriata, Béatrice Kunz, Shixu Yan

Capillary morphogenesis gene 2 (CMG2/ANTXR2) is a cell surface receptor for both collagen VI and anthrax toxin. Biallelic loss-of-function mutations in CMG2 lead to a severe condition, hyaline fibromatosis syndrome (HFS). We have here dissected a network o ...

Enhancing the Signaling of GPCRs via Orthosteric Ions

Horst Vogel, Shuguang Yuan

G protein-coupled receptors play essential roles in cellular processes such as neuronal signaling, vision, olfaction, tasting, and metabolism. As GPCRs are the most important drug targets, understanding their interactions with ligands is of utmost importan ...

Structure of a D2 dopamine receptor-G-protein complex in a lipid membrane

Patrick Daniel Barth, Mahdi Hijazi

The D2 dopamine receptor (DRD2) is a therapeutic target for Parkinson's disease(1)and antipsychotic drugs(2). DRD2 is activated by the endogenous neurotransmitter dopamine and synthetic agonist drugs such as bromocriptine(3), leading to stimulation of G(i) ...

Prospects of Observing Ionic Coulomb Blockade in Artificial Ion Confinements

Aleksandra Radenovic, Andrey Chernev, Sanjin Marion

Nanofluidics encompasses a wide range of advanced approaches to study charge and mass transport at the nanoscale. Modern technologies allow us to develop and improve artificial nanofluidic platforms that confine ions in a way similar to single-ion channels ...

Impairment of Glycolysis-Derived L-Serine Production in Astrocytes Contributes to Cognitive Deficits in Alzheimer's Disease

Graham Knott

Alteration of brain aerobic glycolysis is often observed early in the course of Alzheimer's disease (AD). Whether and how such metabolic dysregulation contributes to both synaptic plasticity and behavioral deficits in AD is not known. Here, we show that th ...

An Experimental Study on Mixed-Dimensional 1D-2D van der Waals Single-Walled Carbon Nanotube-WSe2 Hetero-Junction

Mihai Adrian Ionescu, Farzan Jazaeri, Ali Saeidi, Matteo Cavalieri, Nicolò Oliva, Benjamin Paul Johanès Gabriel Lambert, Sadegh Kamaei Bahmaei, Amin Rassekh

This experimental study investigates a novel multi-functional one dimensional-two dimensional (1D-2D) heterojunction made of two different band-gap semiconductors, i.e. single-walled carbon nanotube (SWCNT) and tungsten di-selenide (WSe2). The proposed ult ...

Probing Context-Dependent Modulations of Ipsilateral Premotor-Motor Connectivity in Relapsing-Remitting Multiple Sclerosis

Estelle Emeline Raffin

Objective: We employed dual-site TMS to test whether ipsilateral functional premotor-motor connectivity is altered in relapsing-remitting Multiple Sclerosis (RR-MS) and is related to central fatigue. ...
