X-ray structure of the mouse serotonin 5-HT3 receptor

Horst Arthur Vogel, Henning Paul-Julius Stahlberg, Rudolf Hovius, Cédric Deluz, Ghérici Hassaïne, Romain Wyss, Luigino Grasso, Menno Berend Tol

Neurotransmitter-gated ion channels of the Cys-loop receptor family mediate fast neurotransmission throughout the nervous system. The molecular processes of neurotransmitter binding, subsequent opening of the ion channel and ion permeation remain poorly un ...

Small effects of smoking on visual spatiotemporal processing

Michael Herzog

Nicotine is an important stimulant that is involved in modulating many neuronal processes, including those related to vision. Nicotine is also thought to play a key role in schizophrenia: A genetic variation of the cholinergic nicotine receptor gene, alpha ...

Long-term behavioral programming induced by peripuberty stress in rats is accompanied by GABAergic-related alterations in the amygdala

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou, Vandana Veenit

Stress during childhood and adolescence is a risk factor for psychopathology. Alterations in γ-aminobutyric acid (GABA), the main inhibitory neurotransmitter in the brain, have been found following stress exposure and fear experiences and are often implica ...

Visual backward masking deficits in schizotypy are observed in late but not early onset nicotine smokers

Michael Herzog, Christine Mohr

Visual backward masking (VBM) is a potential endophenotype for schizophrenia. Relative VBM deficits were also observed in high as compared to low scorers in one schizotypal subdimension (cognitive disorganisation, CogDis; Cappe et al., 2012). VBM deficits ...

Large scale expression and purification of the mouse 5-HT3 receptor

Horst Arthur Vogel, Cédric Deluz, Ghérici Hassaïne, Menno Berend Tol

Receptors of the Cys-loop family are central to neurotransmission and primary therapeutic targets. In order to decipher their gating and modulation mechanisms, structural data is essential. However, structural studies require large amounts of pure, functio ...

Characterization and Validation of Fluorescent Receptor Ligands: A Case Study of the Ionotropic Serotonin Receptor

Rudolf Hovius

The application of fluorescent receptor ligands has become widespread, incited by two important reasons. “Seeing is believing”—it is possible to visualize in real time in live cells ligand–receptor interactions, and to locate the receptors with subcellular ...

Schizophrenia and visual backward masking: a general deficit of target enhancement

Michael Herzog, Maya Roinishvili

The obvious symptoms of schizophrenia are of cognitive and psychopathological nature. However, schizophrenia affects also visual processing which becomes particularly evident when stimuli are presented for short durations and are followed by a masking stim ...

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

Horst Arthur 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 ...
