Vesicular Glutamate Transporters In Cognito
developed that BNP1 might have alternative, or at least additional roles. First, mutations in a BNP1 homolog in C. elegans (eat-4) were noted to cause presynaptic An essential step in chemical synaptic transmission in-deficits in glutamatergic transmission (Berger et al., volves concentration of neurotransmitter into synaptic 1998). Second, immunocytochemical studies of BNP1 vesicles, allowing ...
متن کاملDistribution of vesicular glutamate transporters in the human brain
Glutamate is the major excitatory transmitter in the brain. Vesicular glutamate transporters (VGLUT1-3) are responsible for uploading glutamate into synaptic vesicles. VGLUT1 and VGLUT2 are considered as specific markers of canonical glutamatergic neurons, while VGLUT3 is found in neurons previously shown to use other neurotransmitters than glutamate. Although there exists a rich literature on ...
متن کاملProtons Regulate Vesicular Glutamate Transporters through an Allosteric Mechanism
The quantal nature of synaptic transmission requires a mechanism to transport neurotransmitter into synaptic vesicles without promoting non-vesicular efflux across the plasma membrane. Indeed, the vesicular transport of most classical transmitters involves a mechanism of H(+) exchange, which restricts flux to acidic membranes such as synaptic vesicles. However, vesicular transport of the princi...
متن کاملGlutamate transporters in bone.
In the central nervous system Na(+)-dependent glutamate transporters bind extracellular glutamate and transport it into cells surrounding the synapse, terminating excitatory signals. These glutamate transporters also function as ion channels. The glutamate transporter, GLAST-1, is expressed in the plasma membrane of osteoblasts and osteocytes and is the same molecular weight as in brain. Thus i...
متن کاملAltered expression of vesicular glutamate transporters VGLUT1 and VGLUT2 in Parkinson disease.
Glutamatergic pathways play a key role in the functional organization of neuronal circuits involved in Parkinson disease (PD). Recently, three vesicular glutamate transporters (VGLUT1-3) were identified. VGLUT1 and VGLUT2 are responsible for the uploading of glutamate into synaptic vesicles and are the first specific markers of glutamatergic neurons available. Here, we analyzed the expression o...
