This volume details a collection of laboratory protocols to study asthma in mice and humans. Chapters cover animal models of asthma, methods to measure asthma-related molecules, protocols to detect, isolate, culture and stimulate cells that contribute to asthma in mice and humans, methods to deplete these cells in vivo and study responses of intact airway tissues ex vivo. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols. Authoritative and cutting-edge, Asthma: Methods and Protocols aims to be a foundation for future studies and to be a source of inspiration for new investigations in the field.
