Aptamer Renaissance for Neurochemical Biosensing

Unraveling the complexities of brain function, which is crucial for advancing human health, remains a grand challenge. This endeavor demands precise monitoring of small molecules such as neurotransmitters, the chemical messengers in the brain. In this Pers ...

Different priming states of synaptic vesicles underlie distinct release probabilities at hippocampal excitatory synapses

Maria Reva

A stunning example of synaptic diversity is the postsynaptic target cell-type-dependent difference in synap-tic efficacy in cortical networks. Here, we show that CA1 pyramidal cell (PC) to fast spiking interneuron (FSIN) connections have 10-fold larger rel ...

Cell-type-specific nicotinic input disinhibits mouse barrel cortex during active sensing

Carl Petersen, Sylvain Crochet, Célia Roxane Gasselin, Benoît Hohl

Fast synaptic transmission relies upon the activation of ionotropic receptors by neurotransmitter release to evoke postsynaptic potentials. Glutamate and GABA play dominant roles in driving highly dynamic activity in synaptically connected neuronal circuit ...

Allosteric modulators enhance agonist efficacy by increasing the residence time of a GPCR in the active state

Anne-Marinette Thi Phuong Hanh Cao

Here, the authors use smFRET to assess the structural dynamics of metabotropic glutamate receptor mGlu2 and show that a positive allosteric modulator or the Gi protein stabilize mGlu2 in the glutamate-induced active state, leading to the full activation of ...

Asymmetric opening of the homopentameric 5-HT3A serotonin receptor in lipid bilayers

Horst Vogel, Shuguang Yuan

Pentameric ligand-gated ion channels (pLGICs) of the Cys-loop receptor family are key players in fast signal transduction throughout the nervous system. They have been shown to be modulated by the lipid environment, however the underlying mechanism is not ...

Nicotine increases sleep spindle activity

Christian O'Reilly

Studies have shown that both nicotine and sleep spindles are associated with enhanced memorisation. Further, a few recent studies have shown how cholinergic input through nicotinic and muscarinic receptors can trigger or modulate sleep processes in general ...

High-Affinity Nucleic-Acid-Based Receptors for Steroids

Nako Nakatsuka, Yameng Zhang

Artificial receptors for hydrophobic molecules usually have moderate affinities and limited selectivities. We describe three new classes of high affinity hydrophobic receptors for nonaromatic steroids based on deoxyribonucleotides, obtained through five hi ...

On the role of water density fluctuations in the inhibition of a proton channel

Lucie Monique Françoise Delemotte

Hv1 is a transmembrane four-helix bundle that transports protons in a voltage-controlled manner. Its crucial role in many pathological conditions, including cancer and ischemic brain damage, makes Hv1 a promising drug target. Starting from the recently sol ...

Remarkably Divergent Regions Punctuate the Genome Assembly of the Caenorhabditis elegans Hawaiian Strain CB4856

Tobias Johannes Schmid, Roel Paulus Josephus Bevers

The Hawaiian strain (CB4856) of Caenorhabditis elegans is one of the most divergent from the canonical laboratory strain N2 and has been widely used in developmental, population, and evolutionary studies. To enhance the utility of the strain, we have gener ...

Thermal Unfolding of a Mammalian Pentameric Ligand-gated Ion Channel Proceeds at Consecutive, Distinct Steps

Horst Vogel, Henning Paul-Julius Stahlberg, Cédric Deluz, Ghérici Hassaïne, Menno Berend Tol

Pentameric ligand-gated ion channels (LGICs) play an important role in fast synaptic signal transduction. Binding of agonists to the beta-sheet-structured extracellular domain opens an ion channel in the transmembrane alpha-helical region of the LGIC. How ...
