Tracheal cytotoxin (TCT) is a 921 dalton glycopeptide released by Bordetella pertussis, [1] Vibrio fischeri (as a symbiosis chemical), [2] and Neisseria gonorrhoeae (among other peptidoglycan-derived cytotoxins it produces). [3]
A bacterium, Bordetella pertussis, is able to escape the immune response by inhibiting neutrophils and macrophages from invading the infection site early on. [4] One cause of antigenic escape is that a pathogen's epitopes (the binding sites for immune cells ) become too similar to a person's naturally occurring MHC-1 epitopes, resulting in the ...
