Plasticity of calcium-permeable AMPA glutamate receptors in Pro-opiomelanocortin neurons

eLife, 2017
POMC neurons integrate metabolic signals from the periphery. Here, we show in mice that food deprivation induces a linear current-voltage relationship of AMPAR-mediated excitatory postsynaptic currents (EPSCs) in POMC neurons.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Revisiting Inherited Metabolic Diseases (IMDs) Through the Lens of Selective Autophagy

Journal of Inherited Metabolic Disease, Volume 49, Issue 6, November 2026.
ABSTRACT Selective autophagy is increasingly recognized as a fundamental quality‐control mechanism that complements bulk autophagy by enabling the targeted degradation of specific intracellular cargos, including mitochondria, endoplasmic reticulum (ER), lipid droplets, glycogen, peroxisomes, ferritin, ribosomes, and protein aggregates.

Enhanced Stat3 Activation in POMC Neurons Provokes Negative Feedback Inhibition of Leptin and InsulinSignaling in Obesity

, 2009
Leptin-stimulated Stat3 activation in proopiomelanocortin (POMC)-expressing neurons of the hypothalamus plays an important role in maintenance of energy homeostasis.

Effects of 6‐OHDA‐Mediated Chemical Denervation of Sympathetic Axons in Inguinal Subcutaneous White Adipose Tissue

Diabetes, Obesity and Metabolism, Volume 28, Issue 11, Page 10459-10474, November 2026.
ABSTRACT Aims White adipose tissue (WAT) innervation by sensory and sympathetic axons contributes to tissue functions, but the consequences of selectively disrupting sympathetic input to WAT remain incompletely defined. Materials and Methods We utilised 6‐hydroxydopamine (6‐OHDA) as a validated approach to achieve bilateral sympathetic denervation of ...

Sex difference in physical activity, energy expenditure and obesity driven by a subpopulation of hypothalamic POMC neurons

Molecular Metabolism, 2016
Objective: Obesity is one of the primary healthcare challenges of the 21st century. Signals relaying information regarding energy needs are integrated within the brain to influence body weight.

Early‐Life Betaine Supplementation Drives Sex‐Specific Metabolic Programming in Rats, Affecting FGF21 Signaling and Energy Balance

The FASEB Journal, Volume 40, Issue 20, 31 October 2026.
A maternal western diet (WD) and betaine supplementation during suckling influence metabolic programming. A maternal WD induced adverse metabolic effects in offspring, accompanied by altered FGF21‐related gene expression and decreased Akkermansia muciniphila abundance.

Ciliary Membrane Lipid Homeostasis in Health and Disease

Advanced Science, Volume 13, Issue 58, 19 October 2026.
This review systematically delineates the distinct lipid landscapes of ciliary membranes, including the spatial organization of phosphoinositides, cholesterol, and sphingolipids. It elucidates how these lipids orchestrate ciliogenesis, signal transduction, and membrane dynamics in cilia beating, and highlights how their dysregulation drives ...

Neuropathic Pain Comorbid Cognitive Impairment and Vitamin D: A Narrative Review From Mechanisms to Clinical Management

Food Science &Nutrition, Volume 14, Issue 10, October 2026.
Vitamin D is an essential fat‐soluble nutrient primarily obtained through cutaneous synthesis triggered by ultraviolet exposure and dietary intake. After systemic metabolism and activation, it binds to vitamin D receptors widely distributed in the central and peripheral nervous systems, exerting pleiotropic neuroprotective and regulatory biological ...

Oleic Acid Directly Regulates POMC Neuron Excitability in the Hypothalamus

Journal of Neurophysiology, 2009
The mammalian CNS relies on a constant supply of external glucose for its undisturbed operation. However, neurons can readily switch to using fatty acids and ketones as alternative fuels. Here, we show that oleic acid (OA) excites pro-opiomelanocortin (POMC) neurons by inhibition of ATP-activated potassium (KATP) channels.
