KEYNOTE LECTURE

Endocytic Recycling Pathway Determines the Properties of Neurotransmitter Release

Robert Edwards

Professor of Neurology and Physiology University of California, San Francisco School of Medicine

Abstract:
In the course of studying glutamate corelease by dopamine neurons, we found that the two transmitters signal with different short-term kinetics: the glutamate response depresses more rapidly than the dopamine. Although this might reflect differences in the properties of glutamate and dopamine receptors, we found that release of the two transmitters couples to different presynaptic Ca2+ channels. The direct analysis of individual release events by imaging shows that vesicles storing glutamate and dopamine behave differently even when located at the same presynaptic bouton. The two synaptic vesicle populations also appear to form through different endocytic mechanisms. In contrast to glutamate vesicles which have been shown to recycle dependent on clathrin and its adaptor protein AP-2, monoamine vesicles depend on the related but distinct adaptor AP-3. Thus, different endocytic pathways produce synaptic vesicles with different transmitter content and release properties, with important implications for organization of the nerve terminal and for the processing of information.


General Principles for Timing and Oscillations in Stochastic Reaction Systems


Johan Paulsson

Professor of System Biology Harvard Medical School Department of System Biology

Abstract:

Precise timing can be advantageous in many biological processes but is difficult to achieve because chemical reactions often produce exponentially distributed waiting times for individual events. I will discuss hard bounds on timing and the phase-drift of oscillators in reaction networks with finite numbers of molecules, based on analytical theory for classes of stochastic processes. Based on this theory, I then show how we designed and built a series of ultra-precise synthetic gene oscillators, some of which can oscillate for 500 cell generations without entrainment before drifting out of phase with even half a period. Finally, I will show how some natural systems use the same simple but counterintuitive principles to achieve timing in cell fate decisions, and how these are easily missed in deterministic modeling frameworks.
