To determine the role of surfactant protein-A (SP-A) in host defense, the murine SP-A locus was targeted by homologous recombination to produce mice lacking SP-A. SP-A-/- and wild-type mice were infected with mucoid Pseudomonas aeruginosa by intratracheal instillation. Pulmonary bacterial loads were greater in SP-A-/- than in wild-type mice, with increased(More)
Surfactant protein (SP)-D gene targeted (SP-D-/-) and wild-type mice were infected with respiratory syncytial virus (RSV) by intratracheal instillation. Decreased clearance of RSV was observed in SP-D-/- mice. Deficiency of SP-D was associated with increased inflammation and inflammatory cell recruitment in the lung after infection. In vitro, SP-D bound(More)
Interleukin (IL-) 36 cytokines (previously designated as novel IL-1 family member cytokines; IL-1F5- IL-1F10) constitute a novel cluster of cytokines structurally and functionally similar to members of the IL-1 cytokine cluster. The effects of IL-36 cytokines in inflammatory lung disorders remains poorly understood. The current study sought to investigate(More)
PURPOSE Ventilator-associated pneumonia (VAP) is a nosocomial infection resulting in significant morbidity and mortality. Pseudomonas aeruginosa (P. aeruginosa) and Staphylococcus aureus (S. aureus) are pathogens associated with VAP. Silver (Ag) coating of endotracheal tubes (ETTs) reduces bacterial colonization, however titanium dioxide (TiO(2)) coating(More)
Surfactant protein A (SP-A), a pulmonary collectin, plays a role in lung innate immune host defense. In this study the role of SP-A in regulating the inflammatory response to the flagella of Pseudomonas aeruginosa (PA) was examined. Intra-tracheal infection of SP-A deficient (SP-A-/-) C57BL/6 mice with wild type flagellated PA (PAK) resulted in an increase(More)
Alveolar surfactant modulates the antimicrobial function of bronchoalveolar macrophages (BAM). Little is known about the effect of surfactant-associated proteins in bronchoalveolar lavage fluid (BALF) on the interaction of BAM and Blastomyces dermatitidis. We investigated BALF enhancement or inhibition of TNF-alpha production by BAM stimulated by B.(More)
