An energetic view of stress: Focus on mitochondria

Energy is required to sustain life and enable stress adaptation. At the cellular level, energy is largely derived from mitochondria – unique multifunctional organelles with their own genome. Four main elements connect mitochondria to stress: 1) Energy is r ...

Label-free detection of hypoxia-induced extracellular vesicle secretion from MCF-7 cells

Philippe Renaud, Sandro Carrara, Tugba Kilic, Ana Teresa De Sousa Valinhas

Nanoscale extracellular vesicles (EVs) including exosomes (50–150 nm membrane particles) have emerged as promising cancer biomarkers due to the carried genetic information about the parental cells. However the sensitive detection of these vesicles remains ...

Inner-membrane GspF of the bacterial type II secretion system is a dimeric adaptor mediating pseudopilus biogenesis

Henning Paul-Julius Stahlberg

The type II secretion system (T2SS), a protein complex spanning the bacterial envelope, is pivotal to bacterial pathogenicity. Central to T2SS function is the extrusion of protein cargos from the periplasm into the extracellular environment mediated by a p ...

Formation of Large Hypericin Aggregates in Giant Unilamellar Vesicles-Experiments and Modeling

Jaroslava Joniová, Veronika Huntosova

The incorporation of hypericin (Hyp) from aqueous solutions into giant unilamellar vesicle (GUV) membranes has been studied experimentally and by means of kinetic Monte Carlo modeling. The time evolution of Hyp fluorescence originating from Hyp monomers di ...

Miniaturized single-cell analyses for biomedical applications

Loïc Arvind Roger Arm

Numerous diseases affecting living beings have as a cause a modification of gene expression resulting in anomalous expression of proteins in up- or down-regulated fashion, with altered functions or expression of proteins that are not present in the cell in ...

Versatility of Pyridoxal Phosphate as a Coating of Iron Oxide Nanoparticles

Heinrich Hofmann, Josefina Adriana Maria Bastiaansen, Ulrich Aschauer, Marijana Mionic Ebersold, Débora Bonvin

Pyridoxal 5'-phosphate (PLP) is the most important cofactor of vitamin B-6-dependent enzymes, which catalyses a wide range of essential body functions (e.g., metabolism) that could be exploited to specifically target highly metabolic cells, such as tumour ...

Membrane vesicle secretion and prophage induction in multidrug-resistant Stenotrophomonas maltophilia in response to ciprofloxacin stress

Henning Paul-Julius Stahlberg

Several bacterial species produce membrane vesicles (MVs) in response to antibiotic stress. However, the biogenesis and role of MVs in bacterial antibiotic resistance mechanisms have remained unclear. Here, we studied the effect of the fluoroquinolone cipr ...

Proteoliposomes - a system to study membrane proteins under buffer gradients by cryo-EM

Henning Paul-Julius Stahlberg

Membrane proteins are vital to life and major therapeutic targets. Yet, understanding how they function is limited by a lack of structural information. In biological cells, membrane proteins reside in lipidic membranes and typically experience different bu ...

Generation and Characterization of Anti-VGLUT Nanobodies Acting as Inhibitors of Transport

Andrea Volterra

The uptake of glutamate by synaptic vesicles is mediated by vesicular glutamate transporters (VGLUTs). The central role of these transporters in excitatory neurotransmission underpins their importance as pharmacological targets. Although several compounds ...

Visualizing chemical transport from extracellular symbionts into squid host tissues using NanoSIMS

Stéphanie Kéren Cohen

Chemical communication is the basis of host-microbe interaction. Insights into this communication will provide a deeper understanding of the mechanisms that govern these complex associations, in beneficial as well as pathogenic contexts. In this dissertati ...
