BACKGROUND Cystic fibrosis is a monogenic disease that deranges multiple systems of ion transport in the airways, culminating in chronic infection and destruction of the lung. The introduction of a normal copy of the cystic fibrosis transmembrane conductance regulator (CFTR) gene into the airway epithelium through gene transfer is an attractive approach to(More)
BACKGROUND Obesity is an independent risk factor for morbidity and mortality from pandemic influenza H1N1. Influenza is a significant public health threat, killing an estimated 250,000-500,000 people worldwide each year. More than one in ten of the world's adult population is obese and more than two-thirds of the US adult population is overweight or obese.(More)
Pseudomonas aeruginosa is an opportunistic pathogen that is a major cause of mortality in cystic fibrosis (CF) patients. This bacterium has numerous genes controlled by cell to cell signaling, which occurs through a complex circuitry of interconnected regulatory systems. One of the signals is the Pseudomonas Quinolone Signal (PQS), which was identified as(More)
The pulmonary collectins surfactant protein (SP)-A and SP-D play important roles in innate lung defense, enhancing opsonization of microbes and limiting lung inflammatory responses. To quantify relationships among collectins, bacteria, and inflammation in early cystic fibrosis (CF) airway secretions, bronchoalveolar lavage fluids (BALFs) were collected from(More)
High levels of neutrophils and the neutrophil-attracting chemokine interleukin (IL)-8 have been observed in the airways of patients with cystic fibrosis (CF). We hypothesized that CF respiratory epithelium produces excessive amounts of IL-8 either at baseline or after stimulation. To test this hypothesis we compared immunoreactive IL-8 release by primary(More)
BACKGROUND Epidemiologic evidence links tobacco smoke and increased risk for influenza in humans, but the specific host defense pathways involved are unclear. OBJECTIVE We developed a model to examine influenza-induced innate immune responses in humans and test the hypothesis that exposure to cigarette smoke alters nasal inflammatory and antiviral(More)
OBJECTIVE Obese adults have a greater risk of morbidity and mortality from infection with pandemic H1N1 influenza A virus (pH1N1). The objective of the present study was to elucidate the specific mechanisms by which obesity and overweight impact the cellular immune response to pH1N1. DESIGN AND METHODS Peripheral blood mononuclear cells from healthy(More)
BACKGROUND Modified function of immune cells in nasal secretions may play a role in the enhanced susceptibility to respiratory viruses that is seen in smokers. Innate immune cells in nasal secretions have largely been characterized by cellular differentials using morphologic criteria alone, which have successfully identified neutrophils as a significant(More)
Natural killer (NK) cells are an important lymphocyte population in the nasal mucosa and play important roles in linking the innate and the adaptive immune response. Their two main functions are direct cell-mediated cytotoxicity and the release of cytokines. They are important during viral infections and cancer. Due to their location in the nasal mucosa, NK(More)
BACKGROUND Smokers have increased susceptibility and altered innate host defense responses to influenza virus infection. Broccoli sprouts are a source of the Nrf2 activating agentsulforaphane, and short term ingestion of broccoli sprout homogenates (BSH) has been shown to reduce nasal inflammatory responses to oxidant pollutants. OBJECTIVES Assess the(More)
