Preventing Fucose-dependent Binding of Aspergillus and Pseudomonas to Lung Mucin

2014-09-30 16:38:23 | BioPortfolio

Summary

The investigators will collect samples of sputum from healthy volunteers and patients with cystic fibrosis for the purpose of: a) purifying airway mucins for plate-based binding studies and; b) assessment of the effects of carbohydrates on the rheologic properties of the sputum.

This study has two hypotheses:

1. Lectins from Pseudomonas aeruginosa and Aspergillus fumigatus bind to airway mucins in a fucose-dependent manner, and this binding can be inhibited by fucosyl glycomimetic compounds.

2. Fucosyl glycomimetics will compete with Pseudomonas aeruginosa lectin (PA-IIL) and Aspergillus fumigatus lectin (AFL) and disrupt lectin-driven mucin cross-linking in CF sputum.

Medical and Biotech [MESH] Definitions

An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.

A chloride channel that regulates secretion in many exocrine tissues. Abnormalities in the CFTR gene have been shown to cause cystic fibrosis. (Hum Genet 1994;93(4):364-8)

A strain of mice widely studied as a model for cystic fibrosis. These mice are generated from embryonic stem cells in which the CFTR (cystic fibrosis transmembrane conductance regulator) gene is inactivated by gene targeting. As a result, all mice have one copy of this altered gene in all their tissues. Mice homozygous for the disrupted gene exhibit many features common to young cystic fibrosis patients, including failure to thrive, meconium ileus, and alteration of mucous and serous glands.

A species of STENOTROPHOMONAS, formerly called Xanthomonas maltophilia, which reduces nitrate. It is a cause of hospital-acquired ocular and lung infections, especially in those patients with cystic fibrosis and those who are immunosuppressed.

A rehabilitation therapy for removal of copious mucus secretion from the lung of patients with diseases such as CHRONIC BRONCHITIS; BRONCHIECTASIS; PULMONARY ABSCESS; or CYSTIC FIBROSIS. The patient's head is placed in a downward incline (so the TRACHEA is inferior to the affected area) for 15- to 20-minute sessions.
