The Biology of the Cytolethal Distending Toxins
The cytolethal distending toxins (CDTs), produced by a variety of Gram-negative pathogenic bacteria, are the first bacterial genotoxins described, since they cause DNA damage in the target cells. CDT is an A-B(2) toxin, where the CdtA and CdtC subunits are required to mediate the binding on the surface of the target cells, allowing internalization of the active CdtB subunit, which is functional...
متن کاملInflammatory and Bone Remodeling Responses to the Cytolethal Distending Toxins
The cytolethal distending toxins (CDTs) are a family of exotoxins produced by a wide range of Gram-negative bacteria. They are known for causing genotoxic stress to the cell, resulting in growth arrest and eventually apoptotic cell death. Nevertheless, there is evidence that CDTs can also perturb the innate immune responses, by regulating inflammatory cytokine production and molecular mediators...
متن کاملComparative structure-function analysis of cytolethal distending toxins.
Cytolethal distending toxins (CDTs) constitute a family of bacterial proteins that enter eukaryotic cells with genotoxic activity leading to cell cycle arrest and apoptosis. CDTs are widespread, having been found in a variety of Gram-negative pathogens with a broad tissue tropism. The recently determined crystal structure of the Haemophilus ducreyi CDT provides a powerful starting point for ana...
متن کاملA Journey of Cytolethal Distending Toxins through Cell Membranes
The multifunctional role of lipids as structural components of membranes, signaling molecules, and metabolic substrates makes them an ideal partner for pathogens to hijack host cell processes for their own survival. The properties and composition of unique membrane micro-domains such as membrane rafts make these regions a natural target for pathogens as it affords them an opportunity to hijack ...
متن کاملCytolethal Distending Toxins Require Components of the ER-Associated Degradation Pathway for Host Cell Entry
Intracellular acting protein exotoxins produced by bacteria and plants are important molecular determinants that drive numerous human diseases. A subset of these toxins, the cytolethal distending toxins (CDTs), are encoded by several Gram-negative pathogens and have been proposed to enhance virulence by allowing evasion of the immune system. CDTs are trafficked in a retrograde manner from the c...
