Paraventricular hypothalamic nucleus: Axonal projections to the brainstem [PDF]

Journal of Comparative Neurology, 2010
Abstract The paraventricular hypothalamic nucleus (PVH) contains many neurons that innervate the brainstem, but information regarding their target sites remains incomplete. Here we labeled neurons in the rat PVH with an anterograde axonal tracer, Phaseolus vulgaris ...

Efferent projections of prokineticin 2 expressing neurons in the mouse suprachiasmatic nucleus. [PDF]

PLoS ONE, 2009
The suprachiasmatic nucleus (SCN) in the hypothalamus is the predominant circadian clock in mammals. To function as a pacemaker, the intrinsic timing signal from the SCN must be transmitted to different brain regions.

Hypothalamic Expression of Neuropeptide Y (NPY) and Pro-OpioMelanoCortin (POMC) in Adult Male Mice Is Affected by Chronic Exposure to Endocrine Disruptors

Metabolites, 2021
In the arcuate nucleus, neuropeptide Y (NPY) neurons, increase food intake and decrease energy expenditure, and control the activity of pro-opiomelanocortin (POMC) neurons, that decrease food intake and increase energy expenditure.

Lipopolysaccharide-induced neuronal activation in the paraventricular and dorsomedial hypothalamus depends on ambient temperature. [PDF]

PLoS ONE, 2013
Systemic inflammatory response syndrome is associated with either fever or hypothermia, but the mechanisms responsible for switching from one to the other are unknown.

Oxytocin signaling in the posterior hypothalamus prevents hyperphagic obesity in mice

eLife, 2022
Decades of studies have revealed molecular and neural circuit bases for body weight homeostasis. Neural hormone oxytocin (Oxt) has received attention in this context because it is produced by neurons in the paraventricular hypothalamic nucleus (PVH), a ...

Fasting induced cytoplasmic Fto expression in some neurons of rat hypothalamus. [PDF]

PLoS ONE, 2013
Fat mass and obesity associated protein (Fto) is a nucleic acid demethylase, with a preference for thymine or uracil, according to the recent structural data. This fact suggests that methylated single-stranded RNA, rather than DNA, may be the primary Fto

Opioids in the Hypothalamic Paraventricular Nucleus Stimulate Ethanol Intake [PDF]

Alcoholism: Clinical and Experimental Research, 2010
Background: Specialized hypothalamic systems that increase food intake might also increase ethanol intake. To test this possibility, morphine and receptor‐specific opioid agonists were microinjected in the paraventricular nucleus (PVN) of rats that had learned to drink ethanol.

Time-dependent effects of training on cardiovascular control in spontaneously hypertensive rats: role for brain oxidative stress and inflammation and baroreflex sensitivity.

PLoS ONE, 2014
Baroreflex dysfunction, oxidative stress and inflammation, important hallmarks of hypertension, are attenuated by exercise training. In this study, we investigated the relationships and time-course changes of cardiovascular parameters, pro-inflammatory ...

Chronic stress plasticity in the hypothalamic paraventricular nucleus [PDF]

, 2008
Proper integration and execution of the physiological stress response is essential for maintaining homoeostasis. Stress responses are controlled in large part by the paraventricular nucleus (PVN) of the hypothalamus, which contains three functionally distinct neural populations that modulate multiple stress effectors: (1) hypophysiotrophic PVN neurons ...

Transcriptional regulation of corticotropin-releasing hormone gene in stress response

IBRO Reports, 2018
As a central player of the hypothalamic-pituitary-adrenal (HPA) axis, the corticotropin -releasing hormone (CRH) neurons in the hypothalamic paraventricular nucleus (PVN) determine the state of HPA axis and play a key role in stress response.
