Cell intrinsic immunity spreads to bystander cells via the intercellular transfer of cGAMP

The innate immune defence of multicellular organisms against microbial pathogens requires cellular collaboration. Information exchange allowing immune cells to collaborate is generally attributed to soluble protein factors secreted by pathogen-sensing cell ...

Remote System for Monitoring Animal Models With Single-Metabolite Bio-Nano-Sensors

Giovanni De Micheli, Sandro Carrara, Eric Meurville, Cristina Boero, Andrea Cavallini, Léandre Bolomey

A novel system for remote monitoring of metabolism in an animal model is proposed in this paper. The system is obtained by integrating bio-nano-sensors to detect single- metabolites, an electrochemical front-end made with off-the-shelf components, a radio ...

Chitin colonization, chitin degradation and chitin-induced natural competence of Vibrio cholerae are subject to catabolite repression

Melanie Blokesch

Although Vibrio cholerae is a human pathogen its primary habitat are aquatic environments. In this environment, V. cholerae takes advantage of the abundance of zooplankton, whose chitinous exoskeletons provide a nutritious surface. Chitin also induces the ...

The activation of hepatic and muscle polyamine catabolism improves glucose homeostasis

Eija Riitta Pirinen

The mitochondrial biogenesis and energy expenditure regulator, PGC-1 alpha, has been previously reported to be induced in the white adipose tissue (WAT) and liver of mice overexpressing spermidine/spermine N (1)-acetyltransferase (SSAT). The activation of ...

Fine-tuning the Electronic Structure of Organic Dyes for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Peng Gao, Hoi Nok Tsao

A series of metal-free organic dyes exploiting different combinations of (hetero)cyclic linkers (benzene, thiophene, and thiazole) and bridges (4H-cyclopenta[2,1-b:3,4-b']dithiophene (CPDT) and benzodithiophene (BDT)) as the central pi-spacers were synthes ...

Localized in vivo hyperpolarization transfer sequences

Rolf Gruetter, Mor-Miri Mishkovsky, Tian Cheng, Arnaud Comment

In vivo localized and fully adiabatic homonuclear and heteronuclear polarization transfer experiments were designed and performed in the rat brain at 9.4 T after infusion of hyperpolarized sodium [1,2-(13) C(2) ] and sodium [1-(13) C] acetate. The method p ...

Calorie restriction: is AMPK a key sensor and effector?

Johan Auwerx, Carlos Canto Alvarez

Dietary restriction can extend life span in most organisms tested to date, suggesting that mechanisms sensing nutrient and energy availability might regulate longevity. The AMP-activated protein kinase (AMPK) has emerged as a key energy sensor with the abi ...

Comparison of Three Methods of Biocompatible Multi-Walled Carbon Nanotubes Confinement for the Development of Implantable Amperometric Adenosine-5′-Triphosphate Biosensors

Giovanni De Micheli, Sandro Carrara, Andrea Cavallini

An amperometric biosensor for adenosine 5 -triphosphate (ATP) was developed applying a competitive assay of two glucose converting enzymes: glucose oxidase (GOD) and hexokinase (HEX). Competition between GOD and HEX for glucose in presence of ATP, lead to ...

Evolutionary plasticity of segmentation clock networks

Andrew Charles Oates

The vertebral column is a conserved anatomical structure that defines the vertebrate phylum. The periodic or segmental pattern of the vertebral column is established early in development when the vertebral precursors, the somites, are rhythmically produced ...
