Asthma has rapidly become one of the most common chronic illnesses of the Western world, and its prevalence continues to rise, with the proportion of patients with more severe diseases also increasing. Faced with this problem, more researchers are focusing on the causes, mechanisms, and pathophysiology of asthma. The major hopes are that more effective drugs will become available and that preventive measures can be instituted. Increasingly, molecular and cell bi- ogy approaches are being used to characterize and understand the mechanisms of the inflammatory process that is typical of the asthmatic airway. This volume on Asthma: Mechanisms and Protocols in the Methods in Molecular Medicineseries provides an overview of the molecular mechanisms involved in asthma by p- viding extensive protocols that are being used in asthma research. Briefly, it c- ers details of methods for obtaining cells from the airways, analysis of gene and protein expression in the limited clinical samples from asthmatic airways, use of molecular and cellular tools for studying cytokine expression and release, studies of asthma-related genes and genetic polymorphisms, and understanding the - fects of asthma treatments. With such coverage, the volume ties in several dis- plines, including allergy and immunology, cell biology, pharmacology, and histology. We have continued in the spirit of the series to provide a bench book for day-to-day use.

The last decade or so has seen remarkable advances in our knowledge of cough. This applies especially to its basic mechanisms: the types of airway sensors, the phar- cological receptors on their membranes, the brainstem organization of the ‘cough centre’, and the involvement of the cerebral cortex in the sensations and the vol- tary control of cough. With the exception of the last of these, nearly all the studies have been on experimental animals rather than humans, for obvious reasons. One group of experimental studies has particular relevance to human patients, and that is the demonstration of the sensitization of cough pathways both in the periphery and in the brainstem. Similar sensitizations have been shown for patients with chronic cough or who have been exposed to pollutants, and it is reasonable to suppose that this is the basis of their cough and that the underlying mechanisms are generally similar in humans and other species. Important advances are also being made in clinical cough research. For the three main causes of clinical cough, asthma, post-nasal drip syndrome, and gast- oesophageal re?ux disease, we are beginning to understand the pathological processes involved. There remains a diagnostically obdurate group of idiopathic chronic coughers, but even for them approaches are being devised to clarify und- lying mechanisms and to establish diagnoses. Perhaps surprisingly, the ?eld in which there has been the least spectacular - vance is the therapy of cough.
