Cellular Responses to Bacterial Pore-Forming Toxins
Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
Colicins are unusual bacterial toxins because they are directed against close relatives of the producing strain. They kill their targets in one of three distinct ways; via a ribonuclease or deoxyribonuclease activity or by forming pores in the target cell' ...
Membrane proteins fulfill many central functions in the biological membrane. The insertion process of these proteins and their structure, which are intimately linked to their function, are not yet well understood. As a model we studied three proteins recon ...
Aerolysin is a pore-forming toxin that plays a key role in the pathogenesis of Aeromonas hydrophila infections. In this study, we have analyzed the effect of aerolysin on human granulocytes (HL-60 cells). Proaerolysin could bind to these cells, was process ...
Conformational changes occurring upon membrane binding and subsequent insertion of staphylococcal alpha-toxin were studied using complementary spectroscopic techniques. Experimental conditions were established where binding could be uncoupled from membrane ...
Colicins A and N are pore-forming bacterial toxins that kill Escherichia coli cells. Their mode of action involves three steps; binding to specific receptors located in the outer membrane, translocation through this membrane and the periplasm, and channel ...
