Peripubertal stress increases play fighting at adolescence and modulates nucleus accumbens CB1 receptor expression and mitochondrial function in the amygdala

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti

Play fighting is a highly rewarding behavior that helps individuals to develop social skills. Early-life stress has been shown to alter play fighting in rats and hamsters as well as to increase aggressive behaviors at adulthood. However, it is not known wh ...

Label-free and charge-sensitive dynamic imaging of lipid membrane hydration on millisecond time scales

Sylvie Roke, Orly Bagunu Tarun

Biological membranes are highly dynamic and complex lipid bilayers, responsible for the fate of living cells. To achieve this function, the hydrating environment is crucial. However, membrane imaging typically neglects water, focusing on the insertion of p ...

Casein kinase 2 mediated phosphorylation of Spt6 modulates histone dynamics and regulates spurious transcription

Eric Paquet

CK2 is an essential protein kinase implicated in various cellular processes. In this study, we address a potential role of this kinase in chromatin modulations associated with transcription. We found that CK2 depletion from yeast cells leads to replication ...

Structural and functional analysis of host attachment proteins from contractile injection systems

Michel Plattner

Bacteriophages of the myoviridae family, R-type pyocin, Photorhabus virulence cassette (PVC), Serratia antifeeding prophage (Afp) and type 6 secretion system (T6SS) form a class of contractile injection systems that share common structural and functional c ...

Diazepam actions in the VTA enhance social dominance and mitochondrial function in the nucleus accumbens by activation of accumbal dopamine D1 receptors

Maria del Carmen Sandi Perez, Carlos Canto Alvarez, Jocelin Grosse, Olivia Zanoletti, Marie-Isabelle Guillot de Suduiraut, Fiona Hollis, Michael van der Kooij, Ioannis Zalachoras, Laura Lozano Montes, Sonia Abad Florensa

Benzodiazepines can ameliorate social disturbances and increase social competition, particularly in high-anxious individuals. However, the neural circuits and mechanisms underlying benzodiazepines’ effects in social competition are not understood. Convergi ...

Exploring the role of post-translational modifications in regulating α-synuclein interactions by studying the effects of phosphorylation on nanobody binding

Hilal Lashuel, Juan Kiwi, Bruno Claude Daniel Fauvet, Anass Chiki, Farah El Turk

Intracellular deposits of α-synuclein in the form of Lewy bodies are major hallmarks of Parkinson’s disease (PD) and a range of related neurodegenerative disorders. Post-translational modifications (PTMs) of α-synuclein are increasingly thought to be major ...

Locally coordinated synaptic plasticity of visual cortex neurons in vivo

Graham Knott, Sami El-Boustani

Plasticity of cortical responses in vivo involves activity-dependent changes at synapses, but the manner in which different forms of synaptic plasticity act together to create functional changes in neurons remains unknown. We found that spike timing-induce ...

Neurotrophic-mimetic strategy to rescue synaptic plasticity and cognitive functions in a mouse model of Down syndrome

Diego Ghezzi

Down syndrome (DS) is caused by the triplication of human chromosome 21, and it is the most frequent genetic cause of cognitive disabilities. Although numerous studies have shown that cognitive impairment possibly arises from dysfunction of the hippocampal ...

Potential-sensing electrochemical atomic force microscopy for in operando analysis of water-splitting catalysts and interfaces

Kevin Sivula

Heterogeneous electrochemical phenomena, such as (photo)electrochemical water splitting to generate hydrogen using semiconductors and/or electrocatalysts, are driven by the accumulated charge carriers and thus the interfacial electrochemical potential grad ...

Janus nanostructures for heterogeneous photocatalysis

Monisha Rastogi

Water treatment, the hydrogen evolution reaction, and carbon capture are examples of the potential applications for solar photocatalysis. This has led to significant effort in the search for suitable heterogeneous catalysts. However, materials developed to ...
