Astrocytic VMAT2 in the developing prefrontal cortex is required for normal grooming behavior in mice

Abstract Astrocytes control synaptic activity by modulating peri-synaptic concentrations of ion and neurotransmitters including dopamine and, as such, can be critically involved in the modulation of some aspect of mammalian behavior. Here we report…

P2X7-deficiency improves plasticity and cognitive abilities in a mouse model of Tauopathy

Alzheimer's disease is the most common form of dementia characterized by intracellular aggregates of hyperphosphorylated Tau protein and extracellular accumulation of amyloid β (Aβ) peptides. We previously demonstrated that the purinergic receptor…

Spin-Mechanics with Nitrogen-Vacancy Centers and Trapped Particles

Controlling the motion of macroscopic oscillators in the quantum regime has been the subject of intense research in recent decades. In this direction, opto-mechanical systems, where the motion of micro-objects is strongly coupled with laser light…

Antimicrobial d-amino acid oxidase-derived peptides specify gut microbiota

Abstract The flavoenzyme d -amino acid oxidase (DAAO) is deputed to the degradation of d -enantiomers of amino acids. DAAO plays various relevant physiological roles in different organisms and tissues. Thus, it has been recently suggested that the…

Microwave controlled ground state coherence in an atom-based optical amplifier

We experimentally investigate and theoretically analyze the effect of microwave controlled atomic ground state coherence on the phase-dependent amplification (PDA) of an optical probe field. We use three hyperfine levels in room temperature 85 Rb…

Renormalization of the valence and conduction bands of (C6H5C2H4NH3)2PbI4 hybrid perovskite

Quasi two-dimensional hybrid organic-inorganic perovskites (HOIPs) have been rediscovered recently for photovoltaics due to a higher stability than other HOIPs. We focus here on the electronic structure of the 2D perovskite (C6H5C2H4NH3)2PbI4. We…

Lévitation d’une nanoparticule de diamant dans le vide

Avec les nombreuses applications des pinces optiques, le développement des parti-cules en lévitation dans le vide connaît une période d’essor dans la recherche depuis plusieurs années. Le faible couplage à l’environnement permet d’avoir un système…
