mTOR signaling in the arcuate nucleus of the hypothalamus mediates the anorectic action of estradiol [PDF]
Journal of Endocrinology, 2018 Current evidence suggests that estradiol (E2), the main ovarian steroid, modulates energy balance by regulating both feeding and energy expenditure at the central level, through the energy sensor AMP-activated protein kinase (AMPK). We hypothesized that the hypothalamic mechanistic target of rapamycin (mTOR) pathway, a well-established nutrient sensor ...

Frontiers in Neuroscience, 2015 Sexual behavior is suppressed by various types of stressors. We previously demonstrated that an alarm pheromone released by stressed male Wistar rats is a stressor to other rats, increases the number of mounts needed for ejaculation, and decreases the ...

Roles of estrogen receptor-alpha in mediating life span: the hypothalamic deregulation hypothesis. [PDF]
, 2017 In several species caloric restriction (CR) extends life span. In this paper we integrate data from studies on CR and other sources to articulate the hypothalamic deregulation hypothesis by which estrogen receptor-alpha (ER-α) signaling in the ...

eLife, 2022 Proopiomelanocortin (POMC) neurons of the hypothalamic arcuate nucleus are essential to regulate food intake and energy balance. However, the ontogenetic transcriptional programs that specify the identity and functioning of these neurons are poorly ...

Disruption of type 3 adenylyl cyclase expression in the hypothalamus leads to obesity [PDF]
, 2016 Evidence from human studies and transgenic mice lacking the type 3 adenylyl cyclase (AC3) indicates that AC3 plays a role in the regulation of body weight. It is unknown in which brain region AC3 exerts such an effect.

Dlx1/2 and Otp coordinate the production of hypothalamic GHRH- and AgRP-neurons
Nature Communications, 2018 In the hypothalamus, the arcuate nucleus (ARC) contains AgRP-neurons that regulate energy balance as well as GHRH-neurons that regulate linear growth. Here, the authors looked at how the transcription factors Dlx1/2 and Otp link development of AgRP- and ...

Trypanosoma brucei brucei invasion and T-cell infiltration of the brain parenchyma in experimental sleeping sickness: timing and correlation with functional changes [PDF]
, 2016 Background: The timing of Trypanosoma brucei entry into the brain parenchyma to initiate the second, meningoencephalitic stage of human African trypanosomiasis or sleeping sickness is currently debated and even parasite invasion of the neuropil has ...

The Arcuate Nucleus of the Hypothalamus and Metabolic Regulation: An Emerging Role for Renin–Angiotensin Pathways [PDF]
International Journal of Molecular Sciences, 2021 Obesity is a chronic state of energy imbalance that represents a major public health problem and greatly increases the risk for developing hypertension, hyperglycemia, and a multitude of related pathologies that encompass the metabolic syndrome. The underlying mechanisms and optimal treatment strategies for obesity, however, are still not fully ...

Long-term effects of sleep deprivation on neuronal activity in four hypothalamic areas
Neurobiology of Disease, 2018 Lack of adequate sleep has become increasingly common in our 24/7 society. Unfortunately diminished sleep has significant health consequences including metabolic and cardiovascular disease and mental disorders including depression.
