2. 1. Vesicle proteins as markers for neuroendocrine tumors

   Author : Anne-Marie Levin Jakobsen; Göteborgs universitet; []
   Keywords : Neuroendocrine tumours; gastrointestinal tract; pancreas; adrenal; vesicle proteins; ; SV2; NESP55; VMAT1; VMAT2; MIBG;

   Abstract : The neuroendocrine (NE) tumours comprise a diversity of tumours which share commonproperties, e.g. the capacity to produce, store and release hormones. A prominent feature ofthe NE phenotype is the production of secretory granules with associated vescicle proteins,e. READ MORE

4. 2. Molecular mechanisms in synaptic vesicle recycling

   Author : Joel Jakobsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Neurons communicate through specialized contacts called synapses, which consist of pre- and postsynaptic compartments separated by a narrow synaptic cleft. The stimulus- dependent rapid influx of calcium ions into the presynaptic compartment induces fusion of neurotransmitter-filled vesicles with the plasma membrane and release of their content into the synaptic cleft.

5. 3. Studies of membrane-binding proteins involved in synaptic vesicle recycling

   Author : Fredrik Andersson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Signaling between neurons occurs at synapses. A presynaptic nerve terminal releases neurotransmitter, which diffuses over the synaptic cleft, and binds to postsynaptic receptors. Release occurs by fusion of neurotransmitter-containing vesicles with the plasma membrane. READ MORE

6. 4. The role of multifunctional scaffolding proteins in the synaptic vesicle cycle

   Author : Wei Jiao; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Fast synaptic transmission occurs at specialized junctions between neurons referred to as chemical synapses. Action potentials induce an influx of calcium ions into presynaptic terminals, which contain neurotransmitter-filled synaptic vesicles (SVs), triggering fusion of the vesicles with the plasma membrane and resulting in the release of neurotransmitters.

7. 5. Synaptic vesicle endocytosis studied in a living synapse

   Author : Helge Gad; Karolinska Institutet; Karolinska Institutet; []
   Keywords : synapse; synaptic vesicles; endocytosis; clathrin; calcium; dynamin; endophilin; amphiphysin; synaptojanin; microinjection; electron microscopy;

   Abstract : Neurons in the central nervous system communicate by transmitting electrical signals at special sites of contact called synapses. Synapses contain neurotransmitter-filled synaptic vesicles, which fuse with the presynaptic plasma membrane. The neurotransmitter diffuses to the neighboring neuron and triggers a new electrical signal. READ MORE
