A hypothalamic-thalamostriatal circuit that controls approach-avoidance conflict in rats

Nature Communications, 2021
Animals constantly balance seeking food with avoiding predators. Here, the authors report that CRF positive neurons in the paraventricular thalamus projecting to the nucleus accumbens in rats are an indispensable component of a feedback circuit that can ...

Glucocorticoids and HPA axis regulation in the stress–obesity connection: A comprehensive overview of biological, physiological and behavioural dimensions

Clinical Obesity, Volume 15, Issue 2, April 2025.
Summary Chronic stress, characterized by increased long‐term exposure to the glucocorticoid hormone cortisol, is increasingly linked to obesity development. Still, various knowledge gaps persist, including on underlying pathophysiological mechanisms. The aim of the current review is to provide the latest insights on the connection between stress and ...

Innovations in Obesity Treatment: Beyond Adipose Tissue Dysfunction

Obesity Reviews, EarlyView.
Obesity drives chronic inflammation, insulin resistance, type 2 diabetes, and cancer development through adipocyte dysfunction. Addressing this multisystemic disorder requires integrated strategies beyond diet and exercise, such as thermogenesis activation via menthol or capsinoids and appetite control through GLP‐1/GIP agonists and neuromodulation to ...

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.

Prolonged exposure to artificial light and carcinogenesis: A systematic review of oncostatic mechanisms associated with melatonin pathways

Photochemistry and Photobiology, EarlyView.
Exposure to artificial light at night (ALAN), particularly at blue wavelengths, disrupts circadian rhythms by suppressing melatonin, thereby increasing cancer susceptibility. This systematic review consolidates evidence linking prolonged ALAN exposure to an elevated risk of breast and prostate tumors.

Cardiovascular Function of the Paraventricular Nucleus of the Hypothalamus

Neurosignals, 1995
Recent evidence is showing that the paraventricular nucleus (PVN) of the hypothalamus plays a key role in autonomic regulation. Studies by the author of the PVN neurones that project to the spinal cord are reviewed. These neurones are inhibited by arterial baroreceptors and excited or inhibited by pulmonary/cardiac vagal afferents.

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

The Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Immunoreactivity and distribution of Fos in the mouse brain following diverse general anesthetics

Scientific Reports
General anesthesia induces a range of effects, including unconsciousness, analgesia, amnesia, and immobility. Despite its widespread use for over a century, the underlying mechanisms remain incompletely understood.
