Nicotinic acetylcholine receptors (AChR) belong to a family of proteins that form ligand-gated transmembrane ion channels. They are involved in the fast transmission of signals between cells and the control of intercellular communication in the nervous system. A variety of therapeutic agents and abused drugs, including cocaine, inhibit the AChR and(More)
Recent evidence suggests that the P2X(7) receptor may play a role in the pathophysiology of preclinical models of pain and inflammation. Therefore, pharmacological agents that target this receptor may potentially have clinical utility as anti-inflammatory and analgesic therapy. We investigated and characterized the previously reported P2X(7) antagonist(More)
Xiabin Chen et al. (1) describe pioneering work with a modified drug-metabolizing enzyme, a butyrylcholinesterase (BChE) analog, intended to prolong BChE activity in humans, hoping that the result would be accelerated cocaine metabolism. This work is exciting to those involved in pharmacokinetic approaches to drug toxicity; such constructs promise to be the(More)
