Large dense core vesicles
 | This article needs additional citations for verification. (November 2024) |
Large dense core vesicle (LDCVs) are lipid vesicles in neurons and secretory cells which may be filled with neurotransmitters, such as catecholamines or neuropeptides. LDVCs release their content through SNARE-mediated exocytosis similar to synaptic vesicles.[1] One key difference between synaptic vesicles and LDCVs is that protein synaptophysin which is present in the membrane of synaptic vesicles is absent in LDCVs.[2] LDCVs have an electron dense core which appear as a black circle in micrographs obtained with transmission electron microscopy.[1]
