Pertussis toxin stimulates hypersensitivity and enhances nerve-mediated antigen uptake in rat intestine.

Abstract excerpt

We previously reported that intestine from rats sensitized to ovalbumin (Ova), using Bordetella pertussis vaccine as adjuvant, demonstrated a rapid secretory response [increase in short-circuit current (Isc)] to Ova upon secondary challenge. Here, we examined the role of pertussis toxin, the active component of the vaccine, in the response. Sensitization of Sprague-Dawley rats by intraperitoneal injection of...
