The present volume of the Handbook of Experimental Pharmacology gives a representative survey of the current status of the structure, function, regulation and molecular pharmacology of Neurotransmitter Transporters and aims at providing an overview of insights that were generated in the past 5 years. If the volume serves as both, a useful compendium of current concepts and an inspiring starting point, it will have fulfilled its mission and will be a source for students interested in this emerging field as well as for experienced scientists looking for an update. This volume is the brainchild of the editor-in-chief of the HEP series, Klaus Starke, awe-inspiring to all pharmacologists of younger generations.
