For additional details see Pertussis Toxin-ATP Complex. Pertactin is another toxin produced by Bordetella. For details see P.69 Pertactin Structure and Function. Relevance PT is associated with exacerbated host airway response during whooping cough infection and may inhibit host mechanisms of attenuating inflammation of the airways[2].
