title: Pneumolysin potentiates production of prostaglandin E(2) and leukotriene B(4) by human neutrophils.
abstract: Exposure to pneumolysin (8.37 and 41.75 ng/ml) caused a calcium-dependent increase in the generation of prostaglandin E(2) and leukotriene B(4) by both resting and chemoattractant-activated human neutrophils in vitro. These interactions of pneumolysin with neutrophils may result in dysregulation of inflammatory responses during pneumococcal infection.
