Themed section: Imaging in pharmacology.

This themed section on Imaging in Pharmacology comprising reviews and original articles arose from two symposia held at the Summer Meeting of the British Pharmacological Society in Edinburgh 8-10 July 2009 on Developments in Receptor Imaging and Imaging and Targeting Inflammation in Stroke and Atherosclerosis. The reports cover a broad spectrum of pharmacological studies, from whole animal imaging to gene expression and emphasize the importance of imaging techniques in pharmacology. The development of each new imaging methodology brings pharmacology closer to the ambitious goal of being able to image (simultaneously) each component part of the G-protein-coupled receptor signalling process.
