WebApr 27, 2024 · These compounds inhibit CDTb-induced Vero cell rounding, supporting the hypothesis that CDTb alone is a pore-forming toxin and suggesting the use of pore blockers as potential therapeutic strategies directed at CDT. Colon epithelial cell lines, HCT 116 and CaCo-2, were also protected against toxin effects by chloroquine derivatives. WebCDTs belong to the AB toxin family produced by several groups of Gram-negative bacteria and is composed of an active subunit (CdtB) and two binding subunits (CdtA and CdtC) (AB 2 toxin). 22 The crystal structure solved by Nesic et al. indicates that this holotoxin is a tripartite complex, 23 and thus it is distinguished from binary CDT toxin ... kpms and meditationCdtB is considered the active subunit of the CDT holotoxin. Microinjection of CdtB into susceptible cells without CdtA or CdtC results in the G2/M cell cycle arrest and cytoplasmic distension characteristic of CDT toxins. The structure of CdtB is well-conserved between different bacteria. The CdtB subunit is the … See more Cytolethal distending toxins (abbreviated CDTs) are a class of heterotrimeric toxins produced by certain gram-negative bacteria that display DNase activity.
