Distinct CCK-positive SFO neurons are involved in persistent or transient suppression of water intake

Nature Communications, 2020
Water intake is critical to our life, and the subfornical organ in the brain involved in the control of this behavior. Here, the authors reveal that two distinct groups of CCK-producing neurons in the SFO suppress water intake according to the ...

Sensory Circumventricular Organs, Neuroendocrine Control, and Metabolic Regulation

Metabolites, 2021
The central nervous system is critical in metabolic regulation, and accumulating evidence points to a distributed network of brain regions involved in energy homeostasis.

Reactive oxygen species in the paraventricular nucleus of the hypothalamus alter sympathetic activity during metabolic syndrome.

Frontiers in Physiology, 2015
The paraventricular nucleus of the hypothalamus (PVN) contains heterogeneous populations of neurons involved in autonomic and neuroendocrine regulation.

Role of AT1 receptors at the subfornical organ, in the integration of hydroelectrolytic and energetic balance

, 2023
Although classically involved in cardiovascular control and hydromineral balance, the reninangiotensin system (SRA) has been implicated in energy balance control.

Central interaction between nitric oxide, lactate and glial cells to modulate water and sodium intake in rats

Brain Research Bulletin, 2022
The ''astrocyte-to-neuron lactate shuttle'' (ANLS) mechanism is part of the central inhibitory pathway to modulate sodium intake. An interaction between the GABAergic neurons and nitric oxide (NO) in the subfornical organ (SFO) in salt-appetite ...

Physiological basis of arginine vasopressin deficiency (AVP-D, formerly central diabetes insipidus) and AVP-resistance (AVP-R, formerly nephrogenic diabetes insipidus) [PDF]

Exploration of Medicine
This review explored the physiological mechanisms underlying arginine vasopressin deficiency (AVP-D, formerly central diabetes insipidus) and AVP resistance (AVP-R, formerly nephrogenic diabetes insipidus), with a focus on water balance regulation. Vital

Increased mitochondrial superoxide in the brain, but not periphery, sensitizes mice to angiotensin II-mediated hypertension

Redox Biology, 2017
Angiotensin II (AngII) elicits the production of superoxide (O2•−) from mitochondria in numerous cell types within peripheral organs and in the brain suggesting a role for mitochondrial-produced O2•− in the pathogenesis of hypertension.

The subfornical organ: A novel site for prolactin action [PDF]

Journal of Neuroendocrinology, 2018
Prolactin (PRL) is a peptide hormone that performs over 300 biological functions, including those that require binding to prolactin receptor (PRL‐R) in neurones within the central nervous system (CNS). To enter theCNS, circulatingPRLmust overcome the blood‐brain barrier. Accordingly, areas of the brain that do not possess a blood‐brain barrier, such as

Subfornical organ stimulation excites paraventricular neurons projecting to dorsal medulla

, 1984
Electrical stimulation in the subfornical organ (SFO) of pentobarbital-anesthetized Sprague-Dawley rats was noted to influence the excitability of paraventricular nucleus (PVN) neurons antidromically identified as projecting to the dorsomedial medulla ...

Enalapril decreases angiotensin II receptors in subfornical organ of SHR

, 1989
We studied brain angiotensin II (ANG II) receptors by quantitative autoradiography in adult normotensive Wistar-Kyoto (WKY) rats and in spontaneously hypertensive rats (SHR) after treating the rats with the converting-enzyme inhibitor enalapril, 25 mg ...
