Post-translational glycosylation diminishes α-synuclein pathology formation

Hilal Lashuel

O-linked N-acetylglucosamine (O-GlcNAc) is an endogenous form of glycosylation that alters the structure of alpha-synuclein amyloid fibrils and attenuates their pathogenetic properties. The modified fibrils have a significantly reduced ability to seed the ...

Quantification of Native Lignin Structural Features with Gel-Phase 2D-HSQC0 Reveals Lignin Structural Changes During Extraction

Jeremy Luterbacher, Stefania Bertella, Claire Laura Marion Charline Bourmaud

Our ability to study and valorize the lignin fraction of biomass is hampered by the fundamental and still unmet challenge of precisely quantifying native lignin's structural features. Here, we developed a rapid elevated-temperature H-1-C-13 Heteronuclear S ...

Host-Pathogen Interactions Through the Genomic Lens

Zhi Ming Xu

Hosts and pathogens are involved in a long-standing evolutionary arms race characterized by successive rounds of evolution. Specifically, while hosts evolve resistance against infections, pathogens adapt to re-establish virulence. Since the signatures of t ...

RNA Sequencing of Arabidopsis thaliana Seedlings after Non-Thermal Plasma-Seed Treatment Reveals Upregulation in Plant Stress and Defense Pathways

Ivo Furno, Alan Howling, Alexandra Waskow

Not all agricultural practices are sustainable; however, non-thermal plasma treatment of seeds may be an eco-friendly alternative to improve macroscopic plant growth parameters. Despite the numerous successful results of plasma-seed treatments reported in ...

How Vibrio cholerae adapts to the environment: from cell shape transitions to antagonistic behavior

Leonardo Filipe Lemos Rocha

The bacterium Vibrio cholerae is the causative agent of the diarrheal disease cholera, which affects millions of people every year. Apart from being a human pathogen, V. cholerae is also a common member of aquatic habitats. Whilst the mechanism that allow ...

Plant Terpenes on Treating Cardiovascular and Metabolic Disease: A Review

Rodrigo Araujo Fraga Da Silva

The use of medicinal plants as a therapy alternative is old as human existence itself. Nowadays, the search for effective molecules for chronic diseases treatments has increased. The cardiometabolic disorders still the main cause of death worldwide and pla ...

Rapid molecular evolution of Spiroplasma symbionts of Drosophila

Bruno Lemaitre, Florent François Masson

Spiroplasma is a genus of Mollicutes whose members include plant pathogens, insect pathogens and endosymbionts of animals. Spiroplasma phenotypes have been repeatedly observed to be spontaneously lost in Drosophila cultures, and several studies have docume ...

Linking soil's volatilome to microbes and plant roots highlights the importance of microbes as emitters of belowground volatile signals

Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra, Richard Splivallo

Plants and microbes release a plethora of volatiles that act as signals in plant-microbe interactions. Characterizing soil's volatilome and microbiome might shed light on the nature of relevant volatile signals and on their emitters. This hypothesis was te ...

Ecological implications of gene regulation by TfoX and TfoY among diverse Vibrio species

Melanie Blokesch, Candice Stoudmann, Noémie Matthey, Lisa Christina Metzger

Bacteria of the genus Vibrio are common members of aquatic environments where they compete with other prokaryotes and defend themselves against grazing predators. A macromolecular protein complex called the type VI secretion system (T6SS) is used for both ...

Molecular insights into Vibrio cholerae’s intra-amoebal host-pathogen interactions

Graham Knott, Melanie Blokesch, Sandrine Stutzmann, Catherine Maclachlan, Natalia Carolina Drebes Dorr, Candice Stoudmann, Stéphanie Clerc, Charles Ulric V Van der Henst, Audrey Sophie Vanhove

Vibrio cholerae, which causes the diarrheal disease cholera, is a species of bacteria commonlyfound in aquatic habitats. Within such environments, the bacterium must defend itselfagainst predatory protozoan grazers. Amoebae are prominent grazers, withAcant ...

EspL is essential for virulence and stabilizes EspE, EspF and EspH levels in Mycobacterium tuberculosis

Stewart Cole, Claudia Sala, Andrej Benjak, Nina Theres Odermatt, Paloma Julia Soler Arnedo, Sofia Ulrika Magnusdotter Von Schultz

The ESX-1, type VII, secretion system represents the major virulence determinant of Mycobacterium tuberculosis, one of the most successful intracellular pathogens. Here, by combining genetic and high-throughput approaches, we show that EspL, a protein of 1 ...

Stoichiometric N:P flexibility and mycorrhizal symbiosis favour plant resistance against drought

Pierre Rémi Mariotte

Drought induces changes in the nitrogen (N) and phosphorus (P) cycle but most plant species have limited flexibility to take up nutrients under such variable or unbalanced N and P availability. Both the degree of flexibility in plant N:P ratio and of ro ...

Host and pathogen genomics of severe pediatric infections

Samira Asgari

Infectious diseases are among the leading causes of human morbidity and mortality, with the greatest burden felt in the pediatric population. For any infectious disease, only a fraction of the exposed individuals develop clinical symptoms. These inter-indi ...

Quantitative Single-Cell Analysis of Host-Pathogen Interactions

Matthieu Jean-Hubert Delincé

During infection, microbial pathogens encounter phagocytic cells of the host innate immune system, such as macrophages and neutrophils. These encounters typically lead to uptake and killing of the bacteria by the host cell or, conversely, parasitization of ...

Structure of a pathogen effector reveals the enzymatic mechanism of a novel acetyltransferase family

Shuguang Yuan

Effectors secreted by the type Ill secretion system are essential for bacterial pathogenesis. Members of the Yersinia outer-protein J (YopJ) family of effectors found in diverse plant and animal pathogens depend on a protease-like catalytic triad to acetyl ...

XacFhaB adhesin, an important Xanthomonas citri ssp citri virulence factor, is recognized as a pathogen-associated molecular pattern

Luciano Andres Abriata

Adhesion to host tissue is one of the key steps of the bacterial pathogenic process. Xanthomonas citri ssp. citri possesses a non-fimbrial adhesin protein, XacFhaB, required for bacterial attachment, which we have previously demonstrated to be an important ...

An intracellular replication niche for Vibrio cholerae in the amoeba Acanthamoeba castellanii

Melanie Blokesch, Catherine Maclachlan, Charles Ulric V Van der Henst

Vibrio cholerae is a human pathogen and the causative agent of cholera. The persistence of this bacterium in aquatic environments is a key epidemiological concern, as cholera is transmitted through contaminated water. Predatory protists, such as amoebae, a ...

Kicking Out Pathogens in Exosomes

Françoise Gisou van der Goot Grunberg, Oksana Andrei Sergeeva

Host-pathogen interactions involve a series of attacks and counter-attacks. Miao et al. show that, although some invading bacteria can take shelter in lysosomes by neutralizing their pH, this respite is temporary, as host cells can expel them in exosomes. ...
