Protein-based AB5-type exotoxin Pertussis toxin (PT) is produced by the bacterium Bordetella pertussis. PT can cause whooping cough.
In vitro: PT has the effect on innate immune response. The effects of PT on human monocyte-derived DC (MDDC), including maturation, are regulated by cAMP .
In vivo: Pertussis toxin did not affect the relaxation and contraction properties of isolated NIH or BALB/c mouse trachea, but significantly declined KCl or noradrenaline-induced maximal contraction and decreased sensitivity to noradrenaline in isolated male Wistar rat small mesenteric resistance arteries .
Clinical trial: Pertussis toxin was used as vaccine, acellular pertussis booster immunizations, to young and older persons in order to reduce the community transmission and to enhance the protection. Older persons with infections are mainly asymptomatic. Acellular pertussis boosters provide protection against symptomatic pertussis and give protection against mild and asymptomatic infections. The use of boosters may reduce transmission rate, especially in infant population .
