We investigated the regulatory role of 14-kDa secretory group V phospholipase A(2) (gVPLA(2)) in the development of acute lung injury (ALI) and neutrophilic inflammation (NI) caused by intratracheal administration of LPS. Experiments were conducted in gVPLA(2) knockout (pla2g5(-/-)) mice, which lack the gene, and gVPLA(2) wild-type littermate control (pla2g5(+/+)) mice. Indices of pulmonary injury were evaluated 24 h after intratracheal administration of LPS. Expression of gVPLA(2) in microsections of airways and mRNA content in lung homogenates were increased substantially in pla2g5(+/+) mice after LPS-administered compared with saline-treated pla2g5(+/+) mice. By contrast, expression of gVPLA(2) was neither localized in LPS- nor saline-treated pla2g5(-/-) mice. LPS also caused 1) reduced transthoracic static compliance, 2) lung edema, 3) neutrophilic infiltration, and 4) increased neutrophil myeloperoxidase activity in pla2g5(+/+) mice. These events were attenuated in pla2g5(-/-) mice exposed to LPS or in pla2g5(+/+) mice receiving MCL-3G1, a neutralizing MAb directed against gVPLA(2), before LPS administration. Our data demonstrate that gVPLA(2) is an inducible protein in pla2g5(+/+) mice but not in pla2g5(-/-) mice within 24 h after LPS treatment. Specific inhibition of gVPLA(2) with MCL-3G1 or gene-targeted mice lacking gVPLA(2) blocks ALI and attenuates NI caused by LPS.
