Airway cells use 'tasting' mechanism to detect and clear harmful substances
Date:7/24/2009

study was conducted, worked in the lab of senior study author Michael Welsh, M.D., UI professor of internal medicine and molecular physiology and biophysics, who holds the Roy J. Carver Chair of Internal Medicine and Physiology and Biophysics. Welsh also is a Howard Hughes Medical Institute investigator.

"These findings suggest that we have evolved sophisticated mechanisms to guard ourselves from harmful environmental stimuli," Ben-Shahar said. "Our work also suggests that losing cilia in the lungs, due to smoking or disease, would result in a reduced general ability to detect harmful inhaled chemicals, increasing the likelihood of further damaging an injured lung."
