A Rapid Translational Immune Response Program in CD8 Memory T Lymphocytes

The activation of memory T cells is a very rapid and concerted cellular response that requires coordination between cellular processes in different compartments and on different time scales. In this study, we use ribosome profiling and deep RNA sequencing ...

Microhydration of Biomolecules: Revealing the Native Structures by Cold Ion IR Spectroscopy

Andrei Zviagin, Viktoriia Aladinskaia

The native-like structures of protonated glycine and peptide Gly3H+ were elucidated using cold ion IR spectroscopy of these biomolecules hydrated by a controlled number of water molecules. The complexes were generated directly from an aqueous solution usin ...

Impairment of Glycolysis-Derived L-Serine Production in Astrocytes Contributes to Cognitive Deficits in Alzheimer's Disease

Graham Knott

Alteration of brain aerobic glycolysis is often observed early in the course of Alzheimer's disease (AD). Whether and how such metabolic dysregulation contributes to both synaptic plasticity and behavioral deficits in AD is not known. Here, we show that th ...

Dual Passivation of CsPbI3 Perovskite Nanocrystals with Amino Acid Ligands for Efficient Quantum Dot Solar Cells

Ulf Anders Hagfeldt, Jianhua Liu

Inorganic CsPbI3 perovskite quantum dot (PQD) receives increasing attention for the application in the new generation solar cells, but the defects on the surface of PQDs significantly affect the photovoltaic performance and stability of solar cells. Herein ...

The gut microbiota influences skeletal muscle mass and function in mice

Johan Auwerx, Hongbo Zhang, Walter Wahli

The functional interactions between the gut microbiota and the host are important for host physiology, homeostasis, and sustained health. We compared the skeletal muscle of germ-free mice that lacked a gut microbiota to the skeletal muscle of pathogen-free ...

Increase and homogenization of the endogenous production of protoporphyrin IX by photobiomodulation

Georges Wagnières, Jaroslava Joniová, Emmanuel Louis Arthur Gerelli

Photodynamic therapy (PDT) and/or photodetection (PDD) based on protoporphyrin IX (PpIX) are used in many medical fields. However, the endogenous production of PpIX in tissues after administration of its precursor, 5-aminolevulinic acid (ALA) or derivative ...

Dual action of L-Lactate on the activity of NR2B-containing NMDA receptors: from potentiation to neuroprotection

Pierre Magistretti, Igor Allaman, Pierre Marquet, Pascal Jourdain, Kaspar Rothenfusser

L-Lactate is a positive modulator of NMDAR-mediated signaling resulting in plasticity gene induction and memory consolidation. However, L-Lactate is also able to protect neurons against excito-toxic NMDAR activity, an indication of a mitigating action of L ...

Scanning tunneling microscopy on large bio-molecular systems on surfaces

Sebastian Koslowski

The ever growing demand for the development of new technologies and materials has led to extensive studies inspired by biological functional complexes. Peptides with their outstanding ability to efficiently self-assemble can express a broad spectrum of int ...

Modulation of the endogenous production of protoporphyrin IX in a yeast - based model organism

Georges Wagnières, Jaroslava Joniová, Emmanuel Louis Arthur Gerelli

The main aim of this study was to assess conditions at which simple yeast-based model organism produces maximal levels of protoporphyrin IX (PpIX) after an exogenous administration of its precursor, 5-aminolevulinic acid (ALA), and the ferrous-ion chelator ...

Lifetimes of long-lived states in inhomogeneous magnetic fields

Geoffrey Bodenhausen, Srinivas Chinthalapalli, Maninder Singh

Long-lived states (LLS), also known as singlet states, have been widely studied in the last decade. So far, LLS have only been observed in homogeneous magnetic fields, which preclude applications to many biological samples that are inherently inhomogeneous ...
