OBJECTIVES The objectives of this study were to determine whether a synergistic effect could be obtained in vitro between bovine lactoferricin (B-LFcin) and antibiotics against Pseudomonas aeruginosa and Staphylococcus aureus isolates from ocular infections, and to evaluate the use of B-LFcin as an adjunct to the antibiotic treatment of corneal infection in(More)
BACKGROUND AND OBJECTIVE Exposure to airborne particulate matter (PM) may promote development of childhood asthma and trigger acute exacerbations of existing asthma via injury to airway epithelial cells (AEC). METHODS We compared the response of AEC to ambient particulates with median aerodynamic diameters of <10 μm or <2.5 μm from the Sydney metropolitan(More)
PURPOSE To investigate whether single nucleotide polymorphisms (SNPs) in interleukin (IL)-1β, IL-6, and IL-12β are associated with the susceptibility and severity of contact lens-related keratitis. DESIGN Retrospective, case control study. PARTICIPANTS One hundred twelve cases of keratitis and 225 controls were recruited from studies conducted at(More)
Respiratory viral infections are the most common trigger of acute exacerbations in patients with allergic asthma. The anti-viral response of airway epithelial cells (AEC) may be impaired in asthmatics, while cytokines produced by AEC may drive the inflammatory response. We investigated whether AEC cultured in the presence of Th2 cytokines associated with an(More)
Interleukin-4 (IL-4) has previously been implicated in a protective response to Staphylococcus aureus corneal infection. Consequently, the specific role of IL-4 during S. aureus corneal infection was investigated using IL-4 gene knockout mice. The eyes of IL-4-/- mice and wild-type mice were challenged topically with S. aureus and examined at 24 h(More)
Pseudomonas aeruginosa keratitis is one of the most destructive diseases of the cornea. The host response to this infection is critical to the outcome, and is regulated by cytokines produced in the ocular tissue. In this study, we assessed the relative contribution of the cytokines produced in the cornea to the inflammatory response of the whole eye to gain(More)
There are few alternatives to glucocorticosteroids for treatment of asthma. We assessed the activity of a novel protein drug designated ISU201, the extracellular domain of the human cell surface protein BST2, stabilised by fusion with the Fc region of IgG, in mouse models of mild chronic asthma and an acute exacerbation of asthma. The ability of ISU201 to(More)
Sarcoidosis has often been termed an “immune paradox” as there is peripheral anergy to common recall antigens despite pronounced TH1-dominant inflammation at disease sites, such as the lung, with up-regulation of interferon γ, IL-27 and transcription factors. Peripheral blood may reflect the anergic state, while exhaled breath condensate (EBC) analysis may(More)
Pseudomonas is one of the leading causes of contact lens-related microbial keratitis. Despite the use of antibiotics, the host inflammatory response continues to cause damage to the cornea, which may lead to blindness. CXCR2-binding chemokines have been implicated in the pathogenesis of Pseudomonas keratitis, and the exact role of this receptor remains to(More)
