DESCRIPTION (provided by applicant): Synaptic vesicle dynamics govern the release of neurotransmitter and regulation of synaptic vesicle dynamics will control synaptic function and short-term plasticity. Here, we investigate the function of the a2d subunit of voltage sensitive calcium channels and propose that it is a powerful regulator of synaptic vesicle dynamics. Therefore, altering a2d subunit function via pharmaceutical intervention may slow synaptic vesicle dynamics and reduce neurotransmitter release and enhance short-term depression. a2d ligands are such pharmaceutical intervention and are potent analgesic and anticonvulsant drugs. Thus scrutinizing the function of the a2d subunit will lead to new insights about the regulation of synaptic vesicle dynamics. Furthermore, exploiting the signaling pathway downstream of the a2d subunit may lead to promising, future targets for the development of advanced anticonvulsant and analgesic drugs.
