title: Effects of recombinant human interleukin-1 beta on accumulation of inflammatory peritoneal macrophages in mice treated with pertussis toxin.
abstract: In this study we report that treatment with recombinant human interleukin-1 beta (rIL-1 beta) (10 U per mouse, intraperitoneally) significantly increased the number of inflammatory macrophages in the peritoneal cavity of mice treated with pertussis toxin (PT) (1 micrograms per mouse, intravenously). The administration of rIL-1 beta in a single intraperitoneal dose (10 U per mouse) 1 or 2 days before challenge with PT did not prevent the decrease in the number of inflammatory macrophages in the peritoneal cavity of mice. On the other hand, the simultaneous administration of rIL-1 beta and PT, as well as the administration of rIL-1 beta 24 h after injection of PT, significantly counteracted the inhibitory effect of PT on inflammatory peritoneal macrophages.
