Developmental heterogeneity of embryonic neuroendocrine chromaffin cells and their maturation dynamics [PDF]
Frontiers in Endocrinology, 2022 During embryonic development, nerve-associated Schwann cell precursors (SCPs) give rise to chromaffin cells of the adrenal gland via the “bridge” transient stage, according to recent functional experiments and single cell data from humans and mice ...

High signal-to-noise imaging of spontaneous and 5 ns electric pulse-evoked Ca2+ signals in GCaMP6f-expressing adrenal chromaffin cells isolated from transgenic mice. [PDF]
PLoS ONE, 2023 In studies exploring the potential for nanosecond duration electric pulses to serve as a novel modality for neuromodulation, we found that a 5 ns pulse triggers an immediate rise in [Ca2+]i in isolated bovine adrenal chromaffin cells.

The Role of Nicotinic Receptors on Ca2+ Signaling in Bovine Chromaffin Cells [PDF]
Current Issues in Molecular BiologyChromaffin cells have been used as a physiological model to understand neurosecretion in mammals for many years. Nicotinic receptors located in the cells’ membrane are stimulated by acetylcholine, and they participate in the exocytosis of chromaffin ...

Intestinal microbiota modulates adrenomedullary response through Nod1 sensing in chromaffin cells [PDF]
iScience, 2021 Summary: The intestinal microbiota closely interacts with the neuroendocrine system and exerts profound effects on host physiology. Here, we report that nucleotide-binding oligomerization domain 1 (Nod1) ligand derived from intestinal bacteria modulates ...

Sub-quantal release is not dominant during prolonged depolarization in adrenal chromaffin cells [PDF]
Biophysical ReportsExocytosis, which mediates important functions like synaptic transmission and stress responses, has been postulated to release all transmitter molecules in the vesicle in the “all-or-none” quantal hypothesis.

v-SNARE function in chromaffin cells. [PDF]
Pflugers Arch, 2018 Vesicle fusion is elementary for intracellular trafficking and release of signal molecules, thus providing the basis for diverse forms of intercellular communication like hormonal regulation or synaptic transmission. A detailed characterization of the mechanisms underlying exocytosis is key to understand how the nervous system integrates information ...

Histotopography of the chromaffin tissue of the mouse heart on critical stages of the normal cardioembryogenesis [PDF]
Морфологія, 2015 Background. Pheochromocytoma is tumor of chromaffin tissue, which is very hard to diagnose. Chromaffin tissue present not only in the adrenal gland, but also some cells determined in all organs of the head, neck and body.

Long-term in vitro 2D-culture of SDHB and SDHD-related human paragangliomas and pheochromocytomas
PLoS ONE, 2022 The neuroendocrine tumours paraganglioma and pheochromocytoma (PPGLs) are commonly associated with succinate dehydrogenase (SDH) gene variants, but no human SDH-related PPGL-derived cell line has been developed to date.

Basal and Stress-Induced Network Activity in the Adrenal Medulla In Vivo
Frontiers in Endocrinology, 2022 The adrenal medulla plays a critical role in mammalian homeostasis and the stress response. It is populated by clustered chromaffin cells that secrete epinephrine or norepinephrine along with peptides into the bloodstream affecting distant target organs.

Mitochondria and chromaffin cell function [PDF]
Pflügers Archiv - European Journal of Physiology, 2012 Chromaffin cells are an excellent model for stimulus-secretion coupling. Ca(2+) entry through plasma membrane voltage-operated Ca(2+) channels (VOCC) is the trigger for secretion, but the intracellular organelles contribute subtle nuances to the Ca(2+) signal.
