Splet24. dec. 2024 · Bordetella pertussis infects its host by colonizing lung epithelial cells. The bacterium contains a surface protein, filamentous haemagglutinin adhesin, which binds to the sulfatides found on the cilia of epithelial cells. Once anchored, the bacterium produces tracheal cytotoxin, which stops the cilia from beating.
Tracheal cytotoxin (TCT) is a 921 dalton glycopeptide released by Bordetella pertussis, Vibrio fischeri (as a symbiosis chemical), and Neisseria gonorrhoeae (among other peptidoglycan-derived cytotoxins it produces).
