Research Interests
The focus of research in our laboratory is in the area of cystic fibrosis (CF). CF is the most lethal genetic disease in Caucasians and is characterized by production of excessive amounts of viscous mucus secretions in the airways of the patients. To date the causes of CF airway obstruction is not understood. In addition, the excess mucus in the lungs leads to chronic bacterial infections. Chronic colonization of CF airways with gram negative bacterium Pseudomonas aeruginosa is considered the principal cause of death of CF patients. In our research, we are investigating the molecular basis of P. aeruginosa specific Binding to CF airway mucins.
Our laboratory is also investigating the mechanism of hypersecretion of mucus in CF patients. We are investigating the role of inflammatory mediators and endotoxin in the hypersecretion of mucus in CF.
Our laboratory is investigating the mechanisms of hypersecretion of mucus in CF patients as well as mechanisms that lead to chronic bacterial infections. We are also determining the genomic organization of recently discovered MUC8 airway mucin gene from our laboratory. The determination of promoter region of the MUC8 gene would help understand the regulation of MUC8 gene expression in the disease and healthy states. Our long-term goals are to control hypersecretion of mucus in cystic fibrosis as well as to treat or prevent chronic bacterial infections in CF.
Our laboratory has reported the identification of novel airway mucin gene MUC8. We are investigating the role of MUC8 gene product in the hypersecretion of airway mucus in CF. We are determining the genomic organization of the recently discovered MUC8 gene from our laboratory, We determination of promotor and enhancer regions of the MUC8 gene would help in the understanding of regulation of MUC8 gene expression in the disease and healthy states. Our Long-term goals are to control rate of mucus secretion in cystic fibrosis as well as to treat and/or prevent chronic bacterial infections in CF and thus increase the quality of life for CF patients.
