EM results showed that vGluT2 immunoreactivity was extensively associated with large dense-core vesicles suggesting a unique glutamatergic signaling pathway in GnRH terminals. Large dense-core vesicles LDCVs contain a variety of neurotransmitters proteins and hormones such as biogenic amines and peptides together with microRNAs miRNAs. Dense core vesicles usually contain larger neurotransmitter molecules such as neuropeptides like enkephalin or dynorphin. SIGNIFICANCE STATEMENT Little is known about mechanisms that regulate how neuropeptide-containing dense core vesicles DCVs traffic along the axon how neuropeptide release is orchestrated and where it occurs.
Biogenic amines such as dopamine or serotonin can be stored in small dense core vesicles or large dense core vesicles.
However some vesicles are stationary and may even be loosely tethered to the cell membrane. Peptidergic dorsal root ganglion DRG neurons transmit sensory and nociceptive information from the periphery to the central nervous system. Large dense core vesicles LDCV were found frequently enough in normal guinea pig central white matter basis pontis and spinal cord posterior columns to be regarded as a normal organelle. I the vesicle had to have an electron-dense core ii an intact continuous vesicle membrane had to surround the dense core and iii the membrane had to be approximately circular in geometry. The vesicle in the embryo that later develops into the olfactory bulb and tract. All vesicles meeting these criteria were included in the analysis.

SIGNIFICANCE STATEMENT Little is known about mechanisms that regulate how neuropeptide-containing dense core vesicles DCVs traffic along the axon how neuropeptide release is orchestrated and where it occurs. Dense-core vesicles and insulin vesicles were purified from PC12 and INS1 cells respectively using an iso-osmotic fractionation procedure see Methods Supplementary Fig. Dense core vesicles DCVs are neuronal organelles that transport diverse cargos important for neuron growth and function such as neuropeptides monoamines and neurotrophic factors. The mature of the vesicles depends on the population of neurons. During DCV maturation missorted proteins are removed the intravesicular milieu is acidified and the cargo is condensed.

When present together synaptotagmin-1 and synaptotagmin-7 are found in largely non-overlapping clusters on dense-core vesicles. A review of studies of LDCV and dense core particles DCP which have a different cytological localization and appear to be associated with a variety of diseases suggests that they are the same and hence.
