AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Bacterial typing is of great importance in clinical diagnosis, environmental monitoring, food safety analysis, and biological research. Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) is now widely used to analyze bacterial samples ...
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 ...
Activation of the innate immune response in Metazoans is initiated through the recognition of microbes by host pattern-recognition receptors. In Drosophila, diaminopimelic acid ( DAP)-containing peptidoglycan from Gram-negative bacteria is detected by the ...
The innate immune system needs to distinguish between harmful and innocuous stimuli to adapt its activation to the level of threat. How Drosophila mounts differential immune responses to dead and live Gram-negative bacteria using the single peptidoglycan r ...
Type I interferons (IFN-Is) are fundamental for antiviral immunity, but their role in bacterial infections is contradictory and incompletely described. Streptococcus pyogenes activates IFN-I production in innate immune cells, and IFN-I receptor 1 (Ifnar1)- ...
Pore-forming toxins (PFTs) are virulence factors produced by many pathogenic bacteria and have long fascinated structural biologists, microbiologists and immunologists. Interestingly, pore-forming proteins with remarkably similar structures to PFTs are fou ...
Throughout evolution, both helminths and bacteria have inhabited our intestines. As intestinal helminths and bacteria inhabit the same environmental niche, it is likely that these organisms interact with, and impact on, each other. In addition, intestinal ...
Iron reduction in Gram-positive bacteria is not well understood yet, even if it has been investigated in some extent for Gram-positive bacteria. The mechanisms involved in the delivery of electrons to a solid terminal electron acceptor like iron oxides hav ...
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 ...
One of the major toxins secreted by H. pylori is the Vacuolating cytotoxin A (VacA) named after its ability to induce the formation of "vacuole"-like membrane vesicles in the cytoplasm of gastric cells. VacA has been associated with the disruption of mitoc ...
