Ionic mechanisms and Ca2+ handling in airway smooth muscle

Asthma is a disease characterised by reversible contraction of airway smooth muscle. Many signalling pathways are now known to underlie that contraction, almost all of which revolve around Ca(2+) handling. Ca(2+) homeostasis in turn is governed by a wide variety of ionic mechanisms, which are still poorly understood. The present review will briefly summarise those mechanisms that have been recognised for decades, but will then devote …
