Differential expression of two vesicular monoamine transporters.
Specific transport proteins package classical neurotransmitters into vesicles so that their release can be regulated by neural activity. Previous studies have suggested that a single activity mediates the vesicular transport of monoamines in the adrenal gland, brain, and other tissues such as mast cells and platelets. However, molecular cloning has recently identified two vesicular transporters...
متن کاملMethamphetamine administration reduces hippocampal vesicular monoamine transporter-2 uptake.
Repeated high-dose injections of methamphetamine (METH) rapidly decrease dopamine uptake by the vesicular monoamine transporter-2 (VMAT-2) associated with dopaminergic nerve terminals, as assessed in nonmembrane-associated vesicles purified from striata of treated rats. The purpose of this study was to determine whether METH similarly affects vesicular uptake in the hippocampus; a region innerv...
متن کاملAppendicular Neuroendocrine Tumours in Children: Unicentric Retrospective Study
Background: Neuroendocrine Neoplasms (NEN) represent 60% of all appendicular tumours. This type of cancer is predominantly benign. In this study, appendicular NEN tumours in children were investigated. Materials and Methods: This retrospective study was conducted on 540 patients underwent emergency appendectomy for the treatment of clinically suspected appendicitis at the department of p...
متن کاملIn vivo binding of [11C]tetrabenazine to vesicular monoamine transporters in mouse brain.
The time course of regional mouse brain distribution of radioactivity after i.v. injection of a tracer dose of [11C]tetrabenazine ([11C]TBZ) has been determined. Radiotracer uptake into brain is rapid, with 3.2% injected dose in the brain at 2 min. Egress from the brain is also very rapid, with only 0.21% of the injected dose still present in brain at 60 min. Radiotracer washout is slowest from...
متن کاملThe Vesicular Monoamine Transporter
The vesicular monoamine transporter (VMAT) is a membrane-embedded protein that transports monoamine neurotransmitter molecules into intraneuronal storage vesicles to allow subsequent release into the synapse.1,2 By accumulating both newly synthesized neurotransmitter molecules and freshly returned neurotransmitter molecules from the synapse, VMAT function plays a critical role in the signaling ...
