 Neuropeptides
in central and peripheral nervous systems.
Research in my laboratory aims to understand some of the cellular
and molecular mechanisms that underlie neurotransmission. Synaptic
neurotransmission is spatially precise and rapid in time course. In
contrast, non-synaptic neurotransmission is less focal and is slower.
In each case, neurons organize and deliver to the appropriate region
of their plasma membrane the molecular machinery required for neurotransmitter
packaging and release. Similarly, receptors and signal transduction
molecules are delivered to appropriate regions of the plasma membrane
of recipient neurons.
We study models that represent each of these forms of neurotransmission.
In the case of synaptic neurotransmission we have focused on the neurons
that package adenosine triphosphate (ATP) into vesicles and release
it to act upon neurons that express the P2X family of ATP-gated ion
channels. We investigate non-synaptic neurotransmission through out
studies of the packaging and release of the opioid peptides and their
action on neurons that express opioid receptors. Our general approach
is to generate antibodies that recognize transmitters, receptors,
and other molecules involved in neurotransmission, and to use these
antibodies to monitor the trafficking of the molecules in question. |
