Uptake of Ca2+ by isolated secretory vesicles from adrenal medulla [PDF]

, 1982
Intact secretory vesicles isolated from bovine adrenal medulla contain 94 nmol Na+ per mg of protein, and Ca2+ influx into the vesicles is inhibited by increasing concentrations of extravesicular Na+ (but not of K+, Li+ or choline+) or by addition of the

Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

Advanced Science, Volume 12, Issue 48, December 29, 2025.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

Functional distribution of Ca²⁺-coupled P2 purinergic receptors among adrenergic and noradrenergic bovine adrenal chromaffin cells

BMC Neuroscience, 2007
Background Adrenal chromaffin cells mediate acute responses to stress through the release of epinephrine. Chromaffin cell function is regulated by several receptors, present both in adrenergic (AD) and noradrenergic (NA) cells.

3',5'-Cyclic Adenosine Monophosphate- and Ca2+-Calmodulin-Dependent Endogenous Protein Phosphorylation Activity in Membranes of the Bovine Chromaffin Secretory Vesicles: Identification of Two Phosphorylated Components as Tyrosine Hydroxylase and Protein Kinase Regulatory Subunit Type II [PDF]

, 1983
: Membranes of the secretory vesicles from bovine adrenal medulla were investigated for the presence of the endogenous protein phosphorylation activity. Seven phosphoprotein bands in the molecular weight range of 250,000 to 30,000 were observed by means ...

Atypical presentation of pheochromocytoma as acute ischemic stroke and pulmonary embolism, a case report

UroPrecision, Volume 3, Issue 4, Page 272-280, December 2025.
Abstract Background Pheochromocytoma is a rare catecholamine‐secreting tumor that often presents with symptoms such as hypertension, palpitations, and sweating due to excessive hormone production. In some cases, the catecholamine‐induced vasoconstriction and hypercoagulability associated with pheochromocytomas can lead to cerebrovascular accidents and ...

Preferential localization of a vesicular monoamine transporter to dense core vesicles in PC12 cells. [PDF]

, 1994
Neurons and endocrine cells have two types of secretory vesicle that undergo regulated exocytosis. Large dense core vesicles (LDCVs) store neural peptides whereas small clear synaptic vesicles store classical neurotransmitters such as acetylcholine ...

Distribution of α7 Nicotinic Acetylcholine Receptor Subunit mRNA in the Developing Mouse. [PDF]

, 2019
Homomeric α7 nicotinic acetylcholine receptors (nAChRs) are abundantly expressed in the central and peripheral nervous system (CNS and PNS, respectively), and spinal cord.

Determining the neurotransmitter concentration profile at active synapses [PDF]

, 2009
Establishing the temporal and concentration profiles of neurotransmitters during synaptic release is an essential step towards understanding the basic properties of inter-neuronal communication in the central nervous system.

Distribution of chromaffin secretory vesicles, acetylcholinesterase, and lysosomal enzymes in sucrose and percoll gradients [PDF]

, 1984
Crude chromaffin secretory vesicles, obtained by differential centrifugation, were further purified on isotonic (Percoll) gradients. The chromaffin vesicle fractions recovered from the gradients contain acetylcholinesterase as well as lysosomal enzymes ...
