Research Abstract
Our research focuses on the structure and function of botulinum neurotoxins (BoNTs), which are among the most poisonous substances known to man. BoNTs therefore represent a major bioterrorist threat. Paradoxically, BoNT-containing medicines and cosmetics have been used with great success in clinic. Both the toxic and therapeutic functions of BoNTs indeed rely on a common mechanism to enter neurons, cleave proteins that mediate release of key neurotransmitters, and subsequently paralyze the affected muscles. We are trying to understand the molecular mechanisms underlying the BoNT-host interplay during the course of intoxication. These studies will guide the development of effective anti-BoNT strategies, will help improve clinical efficacy of BoNT-containing drugs, and will suggest novel applications for BoNT.

A second area of our research concerns the structural and functional characterization of ion channels, receptors, and signaling molecules in the nervous system. The brain is a massive network of electrically active cells (neurons) that communicate with each other by signal transmission at specialized intercellular junctions called synapses. We are interested in mechanisms of synapse formation, neurotransmission, and synaptic plasticity. These studies will facilitate the design and improvement of therapeutic agents for the treatment of psychological and neurological disorders.
