Das Genom von Clostridium botulinum A3 Loch Maree (4.259.691 bp) produziert Neurotoxine des Typs A3 und andere Virulenzfaktoren, wobei das bont/A-Gen auf dem Plasmid pCLK_A0076 liegt. Dieser Stamm weist eine hohe Evolutionsrate auf, passt sich an Wirte und Umgebungen an und besitzt 43 einzigartige Virulenz- und Wirtsabwehrgene. Extrachromosomale Elemente verstärken seine Virulenz, darunter Botulismustoxin A3. Von 521 hypothetischen Proteinen sind viele am Aminosäurestoffwechsel beteiligt, und wir haben 13 neue Virulenzproteine vorhergesagt. Ein globales regulatorisches Netzwerkmodell ergab 12 Transkriptionsregulatoren, die homolog zu Bacillus subtilis sind und Virulenzfaktoren kontrollieren. Es wurden ein rekombinanter Untereinheiten- und ein Multiepitop-Impfstoff entwickelt, die auf Proteine wie die Peptidoglykan-Hydrolase und das SCP-ähnliche extrazelluläre Protein abzielen und stabile Interaktionen mit Immunrezeptoren zeigen. Diese Impfstoffe mit minimaler Allergenität sind vielversprechende Kandidaten gegen die Virulenz des A3-Stammes. Die Modellierung von Netzwerken zeigte Wechselwirkungen zwischen Wirt und Mikrobe und identifizierte Linolsäure als einen wichtigen Metaboliten.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...

    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    Joëlle Roche
    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...
