Repair Of The Airway Epithelium: Potential Opportunities For Therapeutic Intervention In Airway Disease, Stephen I. Rennard Jan 1998

Repair Of The Airway Epithelium: Potential Opportunities For Therapeutic Intervention In Airway Disease, Stephen I. Rennard

Journal Articles: Pulmonary & Critical Care Med

The epithelium of the airway has considerable capacity to undergo repair. These repair processes are responsible for maintaining and restoring function after injury of the airways, which likely occurs often as a result of infectious, toxic or other exposures. However, repair processes need not be fully effective. Inadequate repair can take a number of forms and may result in metaplasia, hyperplasia or fibrotic scarring. It is likely that repair processes that lead to tissue disruption play an important role in the chronic airways diseases, such as asthma and bronchitis. Through delineation of these processes, it may become feasible to target …

Efficient Vasoactive Intestinal Polypeptide Hydrolyzing Autoantibody Light Chains Selected By Phage Display, Sonia Tyutyulkova, Qing-Sheng Gao, Austin Thompson, Stephen I. Rennard, Sudhir Paul

Journal Articles: Pulmonary & Critical Care Med

An immunoglobulin light chain (L chain) library derived from the peripheral blood lymphocytes of a patient with asthma was cloned into a phagemid vector. Phage particles displaying L chains capable of binding vasoactive intestinal polypeptide (VIP) were isolated by affinity chromatography. Two VIP binding L chains were expressed in Escherichia coli in soluble form and purified to electrophoretic homogeneity by metal chelating and protein L affinity chromatography. Both L chains catalyzed the hydrolysis of [tyr10-125I]VIP substrate. The catalytic activity eluted at the molecular mass of the monomer form of the L chain (28 kDa) from a gel filtration column. The …
