General description
La toxine cholérique et sa sous-unité A sont souvent utilisées pour étudier les mécanismes de transduction du signal en raison de leur effet sur l'adénylate cyclase. La toxine cholérique sert aussi d'adjuvant en stimulant la réponse des lymphocytes B et des lymphocytes Th2 par inhibition de la production d'interleukine-12. La sous-unité B (CTB), non toxique, se fixe aux cellules en se liant au ganglioside GM1, ce qui en fait un marqueur utile des cellules microgliales pour la recherche neurologique. Elle s'est également avérée être un excellent traceur pour les études sur le transport axonal par des méthodes immunohistochimiques.
