Cortical‐Hypothalamic Assembloids Uncover the Cortical Regulation of Hypothalamic Responses to Fatty Acid

Cell Proliferation, EarlyView.
By assembling cortical‐hypothalamic circuits, we show that cortical input protects hypothalamic neurons from fatty acid‐induced damage, which activates PGC1α to boost mitochondrial function. This reveals a cortico‐hypothalamic axis that defends against metabolic stress.

Conditional Expression ofPomcin theLepr-Positive Subpopulation of POMC Neurons Is Sufficient for Normal Energy Homeostasis and Metabolism [PDF]

Endocrinology, 2015
Peptides derived from the proopiomelanocortin (POMC) precursor are critical for the normal regulation of many physiological parameters, and POMC deficiency results in severe obesity and metabolic dysfunction. Conversely, augmentation of central nervous system melanocortin function is a promising therapeutic avenue for obesity and diabetes but is ...

ACTH suppression and adverse effects of cabergoline in horses with pituitary pars intermedia dysfunction

Equine Veterinary Education, EarlyView.
Summary Background The diagnosis and management of pituitary pars intermedia dysfunction (PPID) in horses includes evaluating abnormal plasma concentrations of adrenocorticotrophic hormone (ACTH). Treatment commonly includes the oral dopamine agonist pergolide mesylate, which suppresses the pathologic overproduction of ACTH.

Ire1α in Pomc Neurons Is Required for Thermogenesis and Glycemia [PDF]

Diabetes, 2016
Whether neuronal inositol-requiring enzyme 1 (Ire1) is required for the proper regulation of energy balance and glucose homeostasis is unclear. We found that pro-opiomelanocortin (Pomc)–specific deficiency of Ire1α accelerated diet-induced obesity concomitant with a decrease in energy expenditure.

Postprandial Hyperglycemia Stimulates Neuroglial Plasticity in Hypothalamic POMC Neurons after a Balanced Meal

Cell Reports, 2020
Summary: Mechanistic studies in rodents evidenced synaptic remodeling in neuronal circuits that control food intake. However, the physiological relevance of this process is not well defined.

Toll Like Receptor 4: A Potential Link Between Obesity and Metabolic Diseases

Obesity Reviews, EarlyView.
ABSTRACT Epidemiological evidence shows that obesity increases the risk of developing metabolic diseases. Nevertheless, the mechanisms behind this connection remain underappreciated. The substantial impact of these disorders on global health has led to extensive research efforts aimed at identifying the pathophysiological links between them.

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 ...

TRPC1/5-CaV3 Complex Mediates Leptin-Induced Excitability in Hypothalamic Neurons

Frontiers in Neuroscience, 2021
Leptin regulates hypothalamic POMC+ (pro-opiomelanocortin) neurons by inducing TRPC (Transient Receptor Potential Cation) channel-mediate membrane depolarization.

Setmelanotide in Bardet‐Biedl Syndrome: A Case Report

Pediatric Dermatology, EarlyView.
ABSTRACT Setmelanotide is a melanocortin‐4‐receptor agonist used for the treatment of hyperphagia in the genetic obesity syndrome Bardet‐Biedl. Presented is a case of diffuse hyperpigmentation in a patient treated with setmelanotide, which represents the most common side effect of this medication.

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.
