Mechanisms protecting host cells against bacterial pore-forming toxins

Francisco De Magalhães Sarmento R De Mesquita

Pore-forming toxins (PFTs) are key virulence determinants produced and secreted by a variety of human bacterial pathogens. They disrupt the plasma membrane (PM) by generating stable protein pores, which allow uncontrolled exchanges between the extracellula ...

Folding and Endocytosis of Anthrax Toxin Receptors

Bacillus anthracis is the causative agent of the infectious disease anthrax. The disease is caused after taking up the spores by either inhalation, ingestion or through skin lesion. They then germinate inside the body and start secreting the tripartite ant ...

Molecular Modeling of Bacterial Nanomachineries

Matteo Thomas Degiacomi

Proteins have the ability to assemble in multimeric states to perform their specific biological function. Unfortunately, characterizing experimentally these structures at atomistic resolution is usually difficult. For this reason, in silico methodologies a ...

Folding and Structure of the Pore Forming Toxin Aerolysin

Mircea Ioan Iacovache

The first obstacle encountered by a bacterial pathogen once inside the host is the plasma membrane surrounding the target cells. Throughout evolution bacteria has acquired and maintained genes that upon stimulation express proteins capable of damaging the ...

Cellular Responses to Bacterial Pore-Forming Toxins

Rodrigo Manuel Gonzalez

Pore-forming toxins (PFTs) represent the largest class of bacterial protein toxins and constitute major virulence factors produced by pathogenic bacteria during infection. Pore formation appears to be an ancient form of attack, which is also found in hydro ...

Monalysin, a novel ß-pore-forming toxin from the Drosophila pathogen Pseudomonas entomophila, contributes to host intestinal damage and lethality

Françoise Gisou van der Goot Grunberg, Mircea Ioan Iacovache, Rodrigo Manuel Gonzalez, Bruno Lemaitre, Onya Opota

Pseudomonas entomophila is an entomopathogenic bacterium that infects and kills Drosophila. P. entomophila pathogenicity is linked to its ability to cause irreversible damages to the Drosophila gut, preventing epithelium renewal and repair. Here we report ...

Genetic evidence for a protective role of the peritrophic matrix against intestinal bacterial infection in Drosophila melanogaster

Bruno Lemaitre, Onya Opota, Olivier Binggeli, Takayuki Kuraishi

The peritrophic matrix (PM) forms a layer composed of chitin and glycoproteins that lines the insect intestinal lumen. This physical barrier plays a role analogous to that of mucous secretions of the vertebrate digestive tract and is thought to protect the ...

Bacterial pore-forming toxins: the (w)hole story?

Mirko Bischofberger, Françoise Gisou van der Goot Grunberg, Rodrigo Manuel Gonzalez

Pore-forming toxins (PFTs) are the most common class of bacterial protein toxins and constitute important bacterial virulence factors. The mode of action of PFT is starting to be better understood. In contrast, little is known about the cellular response t ...
