Airway tissue obtained postmortem from nondiseased and severely asthmatic human lung was used in functional, radioligand binding and autoradiographic studies to investigate aspects of various receptor systems for putative mediators of asthma. Results indicate that asthma does not involve an intrinsic abnormality of smooth muscle ...
