provides a clear summary of the current knowledge in this fast-evolving field. The book sets out with an introduction to signalling molecules and their receptors, and an overview of the technical approaches used to investigate these interactions. Structural, functional and especially pharmacological aspects of GPCRs are then discussed in more detail and much attention is devoted to the analysis and interpretation of experimental data. The now widespread use of recombinant cell lies, receptor mutants and related artifices in drug research is critically evaluated. Special attention is also devoted to topical but often poorly understood concepts, such as insurmountable antagonism, inverse agonism and allosteric interactions. By combining general information with the major state-of-the-art concepts in GPCR-research, this outstanding book equips the reader with the necessary background for understanding and critically evaluating the current literature. Written by two experts from academia and industry, offers a unique view of academic and applied approaches aiming to reveal new ideas in pharmaceutical research. The book is of interest to anyone involved in drug development and preclinical research and those who need to function within multi-disciplinary teams in the pharmaceutical industry: from investigators to product managers or clinicians who seek to have a broad mechanistic understanding of drug-receptor interactions. It is also an invaluable resource for final year undergraduate and postgraduate students in pharmacology and cell and molecular biology.
