Dopamine transmission is involved in reward processing and motor control, and its impairment plays a central role in numerous neurological disorders. Despite its strong pathophysiological relevance, the molecular and structural organization of the dopaminergic synapse remains to be established. Here, we used targeted labelling and fluorescence activated sorting to purify striatal dopaminergic synaptosomes. We provide the proteome of dopaminergic synapses with 57 proteins specifically enriched. Beyond canonical markers of dopamine neurotransmission such as dopamine biosynthetic enzymes and cognate receptors, we validated 6 proteins not previously described as enriched. Moreover, our data reveal the adhesion of dopaminergic synapses to glutamatergic, GABAergic or cholinergic synapses in structures we named “dopamine hub synapses”. At glutamatergic synapses, pre- and postsynaptic markers are significantly increased upon association with dopamine synapses. Dopamine hub synapses may thus support local dopaminergic signalling, complementing volume transmission thought to be the major mechanism by which monoamines modulate network activity. The neurotransmitter dopamine is an important regulator of brain function. Here the authors describe “dopamine hub synapses”, where dopamine transmission may act in synergy with other neurotransmitters.

Dies ist ein Crosspost eines für Facebook geschriebenen Artikels. Hier auf meinem Blog habe ich das Gefühl, dass ich nur zum Chor predige, denn Blogs werden in Deutschland nur von genau der Minderheit gelesen, die eh ungefähr weiß, was ACTA ist. Es kann ja aber dennoch nicht schaden, den Text auch noch mal hier zu veröffentlichen. Dennoch wäre es schön, wenn ihr ihn – in welcher Form auch immer – vor allem auf Facebook verbreitet. Einfach, weil er dort die größten Chancen hat, die Richtigen zu erreichen.
