Evolution of the "Castanea sativa" - "Dryocosmus kuriphilus" - "Torymus sinensis" - system in southern Switzerland

Gehring, Eric ; Aebi, Alexandre (Dir.) ; Conedera, Marco (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

L’arrivée de nouveaux organismes qui peuvent s’avérer potentiellement nuisibles à l’égard des personnes et des écosystèmes est devenu un objet de préoccupation quotidienne, à tel point qu’il existe en Suisse environ 800 espèces reconnues d’organismes étrangers, dont au moins 107 sont considérées invasives. Pour maîtriser ce genre d’insectes nuisibles l’une des méthodes...

Thin-film structural coloration from simple fused scales in moths

Kilchoer, Cédric ; Steiner, Ullrich ; Wilts, Bodo D.

In: Interface Focus, 2019, vol. 9, no. 1, p. 20180044

The metallic colouration of insects often originates from diverse nanostructures ranging from simple thin films to complex three-dimensional photonic crystals. In Lepidoptera, structural colouration is widely present and seems to be abundant in extant species. However, even some basal moths exhibit metallic colouration. Here, we have investigated the origin of the vivid metallic colours of...

Dissecting human antibody responses: useful, basic and surprising findings

Lanzavecchia, Antonio

In: EMBO molecular medicine, 2018, vol. 10, p. e8879

Human memory B cells and plasma cells represent a rich source of antibodies that have been selected in response to human pathogens. In the last decade, different methods have been developed to interrogate the human memory repertoire and isolate monoclonal antibodies. I will discuss how a target‐agnostic approach based on high‐throughput screening of antibodies produced by cultured B cells...

New insights in chemokine signaling

Legler, Daniel F. ; Thelen, Marcus

In: F1000Research, 2018, vol. 7, p. 95

Chemokine signaling is essential for coordinated cell migration in health and disease to specifically govern cell positioning in space and time. Typically, chemokines signal through heptahelical, G protein-coupled receptors to orchestrate cell migration. Notably, chemokine receptors are highly dynamic structures and signaling efficiency largely depends on the discrete contact with the ligand....

Distribution and restoration of serotonin-immunoreactive paraneuronal cells during caudal fin regeneration in zebrafish

König, Désirée ; Dagenais, Paule ; Senk, Anita ; Djonov, Valentin ; Aegerter, Christof M. ; Jaźwińska, Anna

In: Frontiers in Molecular Neuroscience, 2019, vol. 12, p. -

Aquatic vertebrates possess diverse types of sensory cells in their skin to detect stimuli in the water. In the adult zebrafish, a common model organism, the presence of such cells in fins has only rarely been studied. Here, we identified scattered serotonin (5-HT)-positive cells in the epidermis of the caudal fin. These cells were distinct from keratinocytes as revealed by their low...

Mood effects after deep brain stimulation for Parkinson’s disease: an update

Accolla, Ettore A. ; Pollo, Claudio

In: Frontiers in Neurology, 2019, vol. 10, p. 617

Depression in Parkinson's Disease (PD) is a prevalent and invalidating symptom. Deep brain stimulation (DBS) allows for an improvement of PD motor features, but its effects on mood are difficult to predict. Here, we review the evidence regarding mood effects after DBS of either subthalamic nucleus (STN) or globus pallidus pars interna (GPi). Different influences of multiple factors contribute...
