Webb21 mars 2024 · The signaling modulation in the synaptic transmission carried out by opioid receptors is crucial at pre- and post-synaptic levels. Indeed, their activation triggers a cascade of events causing the reduction of neurotransmitter release and membrane hyperpolarization [ 14, 15 ]. WebbThe receptors then transduce these extracellular signals across the plasma membrane and, through the activation of intracellular signalling pathways, bring about the appropriate functional response. Moreover, cells have developed sophisticated systems to integrate inputs from multiple signals. In this review, we will discuss the various means ...
