Entering neurons: botulinum toxins and synaptic vesicle recycling.
Botulinum toxins are metalloproteases that act inside nerve terminals and block neurotransmitter release through their cleavage of components of the exocytosis machinery. These toxins are used to treat human diseases that are characterized by hyperfunction of cholinergic terminals. Recently, evidence has accumulated that gangliosides and synaptic vesicle proteins cooperate to mediate toxin bind...
متن کاملBotulinum Neurotoxins Can Enter Cultured Neurons Independent of Synaptic Vesicle Recycling
Botulinum neurotoxins (BoNTs) are the causative agent of the severe and long-lasting disease botulism. At least seven different serotypes of BoNTs (denoted A-G) have been described. All BoNTs enter human or animal neuronal cells via receptor mediated endocytosis and cleave cytosolic SNARE proteins, resulting in a block of synaptic vesicle exocytosis, leading to the flaccid paralysis characteris...
متن کاملReduced Synaptic Vesicle Recycling during Hypoxia in Cultured Cortical Neurons
Improvement of neuronal recovery in the ischemic penumbra, an area around the core of a brain infarct with some remaining perfusion, has a large potential for the development of therapy against acute ischemic stroke. However, mechanisms that lead to either recovery or secondary damage in the penumbra largely remain unclear. Recent studies in cultured networks of cortical neurons showed that fai...
متن کاملSynaptic Transmission: Kinetics of synaptic-vesicle recycling
The kinetics of different steps in synaptic-vesicle recycling, including exocytosis, internalization and repriming, have recently been estimated in various types of living cell.
متن کاملSynaptic vesicle recycling: steps and principles
Synaptic vesicle recycling is one of the best-studied cellular pathways. Many of the proteins involved are known, and their interactions are becoming increasingly clear. However, as for many other pathways, it is still difficult to understand synaptic vesicle recycling as a whole. While it is generally possible to point out how synaptic reactions take place, it is not always easy to understand ...
