Leukotriene B4 stimulates human polymorphonuclear leukocytes to synthesize and release interleukin-8 in vitro.


Interleukin-8 (IL-8) is a potent chemotactic protein for polymorphonuclear leukocytes (PMN). Here we examine whether PMN synthesize and release IL-8 in response to stimulation by leukotriene B4 (LTB4). PMN isolated from normal heparinized peripheral human blood were incubated in RPMI culture medium at 37 degrees C in 5% CO2, with and without LTB4. The… (More)
