Involvement of prostaglandin E1 in delayed-type hypersensitivity suppression induced with live Mycobacterium bovis
Infection and Immunity
|April 1, 1982
Abstract:
We previously showed the suppression of delayed-type hypersensitivity produced by live BCG-induced, plastic-adhering cells. The present study was undertaken to determine whether prostaglandin was one of the pharmacological mediators involved in this suppression. A high level of prostaglandin E1 was detected in the culture supernatant fluid of the live BCG-induced, adherent cells. Moreover, prostaglandin E1 could suppress the macrophage migration inhibition activity of peritoneal exudate cells from BCG cell wall-sensitized mice.
