S-acylation and lipid exchange at the ER-Golgi membrane contact sites regulate pathogen entry in human cells

Muhammad Umair Anwar

Cells have evolved endocytic pathways to internalize different molecules, to regulate intra-cellular communication and their interaction with external environment. Pathogens have co-evolved with cells to exploit these processes for infections. In particula ...

The World Health Organization highlights the urgent need to address the global threat posed by antibiotic-resistant bacteria. Efficient and rapid detection of bacterial response to antibiotics and their virulence state is crucial for the effective treatmen ...

Inhibitors of acyl protein thioesterases against microbial infections

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Valeria Cagno

The present invention relates inhibitors of acyl protein thioesterases and method of preparation thereof. It also relates to the use of inhibitors of acyl protein thioesterases in the treatment and/or prevention of a microbial infection such as viral or ba ...

Implantation of Bacillus pseudomycoides Chromate Transporter Increases Chromate Tolerance in Bacillus subtilis

Rizlan Bernier-Latmani, Barbora Bártová, Imrich Barak, Zuzana Chromiková

Chromium of anthropogenic origin contaminates the environment worldwide. The toxicity of chromium, a group I human carcinogen, is greatest when it is in a hexavalent oxidation state, Cr(VI). Cr(VI) is actively transported into the cell, triggering oxidativ ...

Enteroviruses are ubiquitous contaminants of surface waters, yet their fate in presence of microbial congeners is poorly understood. In this work, we investigated the inactivation of Echovirus-11 (E11) and Coxsackievirus-A9 (CVA9) by bacteria isolated from ...

Urinary tract infections (UTIs) are amongst the most common bacterial infections and are the second-most frequent reason for antibiotic prescriptions. Moreover, in about 25% of all treated cases, recurrence of infection occurs. Uropathogenic Escherichia co ...

Carbohydrate recognition by lectins governs critical host-microbe interactions. MpPA14 (Marinomonas primoryensis PA14 domain) lectin is a domain of a 1.5-MDa adhesin responsible for a symbiotic bacterium-diatom interaction in Antarctica. Here, we show that ...

Caenorhabditiselegans (C. elegans) has gained importance as a model for studying host-microbiota interactions and bacterial infections related to human pathogens. Assessing the fate of ingested bacteria in the worm's intestine is therefore of great interes ...
