Acute lung injury in rats following systemic activation of complement by i.v. infusion of cobra venom factor (CVF) is known to be P-selectin dependent. In the current studies, infusion of CVF caused the appearance in plasma of C5a (as revealed by ELISA analysis) together with neutrophil chemotactic activity, which was totally blocked by addition in vitro of anti-rat C5a. Using a detector 125I-labeled antibody to rat P-selectin, we have demonstrated quantitative up-regulation in vivo of lung vascular P-selectin in a time-dependent manner after infusion of CVF. This up-regulation was almost completely blocked by prior complement depletion or by the infusion of anti-rat C5a. Platelet depletion did not affect CVF-induced up-regulation of lung vascular P-selectin, indicating that platelets were not the source of P-selectin. These results demonstrate that complement and, specifically, C5a are necessary for up-regulation of lung vascular P-selectin after systemic activation of complement.
