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.

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 ...

Activation of Stat3 Signaling in AgRP Neurons Promotes Locomotor Activity [PDF]
Cell Metabolism, 2008 Leptin, an adipocyte-derived hormone, acts on hypothalamic neurons located in the arcuate nucleus (ARC) of the hypothalamus to regulate energy homeostasis. One of the leptin-regulated neuronal subtypes in the ARC are agouti-related peptide (AgRP)-expressing neurons, which are involved in the regulation of food intake and are directly inhibited by ...

The Journal of Physiology, EarlyView.Abstract figure legend Central leptin signalling blockade induces early metabolic dysfunction. Intracerebroventricular infusion of a leptin receptor antagonist (SLA) in rats disrupts hypothalamic leptin signalling, leading to reduced signal transducer and activator of transcription 3 (STAT3) activation, decreased Socs3 and Pomc expression, and ...

Neurobehavioural Genes Associated With Growth in Dusky Kob (Argyrosomus japonicus)
Animal Genetics, Volume 57, Issue 3, June 2026.ABSTRACT Growth is a complex trait, influenced by numerous genes and environmental factors that transect various physiological pathways. This study sought to characterise the relationship between neurobehavioural development genes and growth in dusky kob juveniles.

AGRP neurons modulate fasting-induced anxiolytic effects
Translational Psychiatry, 2019 AbstractRecent studies indicate that activation of hypothalamic Agouti-related protein (Agrp) neurons can increase forage-related/repetitive behavior and decrease anxiety levels. However, the impact of physiological hunger states and food deprivation on anxiety-related behaviors have not been clarified.

Food Science &Nutrition, Volume 14, Issue 6, June 2026.Hydroxy‐alpha‐sanshool could modulate the expression of appetite‐related factors and the composition of intestinal microbiota in mice fed with a high‐fat diet by regulating food intake and maintaining energy homeostasis, which is consistent with the involvement of the gut‐brain axis in this regulatory mechanism.

Cilia in Nervous System Development, Function, and Disease
MedComm – Future Medicine, Volume 5, Issue 2, June 2026.Cilia are evolutionarily conserved organelles that function as essential sensory and motility platforms in the nervous system. This review outlines key cilia‐dependent signaling pathways and their roles in neural development and function. Furthermore, it highlights how ciliary dysfunction can lead to a variety of neurological disorders, known as ...

Obesity, Volume 34, Issue S1, Page 77-87, June 2026.This study identifies G protein‐coupled receptor 17 (Gpr17) as a novel regulator of leptin and insulin sensitivity. Using complementary knockout models, we demonstrate that Gpr17 deletion enhances energy expenditure, restores leptin responsiveness, and improves insulin sensitivity, revealing Gpr17 as a potential therapeutic GPCR target for obesity and ...

Diabetes, Obesity and Metabolism, Volume 28, Issue 6, Page 5184-5194, June 2026.ABSTRACT Aims Semaglutide is a GLP‐1 receptor agonist for the treatment of type 2 diabetes and obesity. Its clinical effects are well established, but the underlying mechanisms remain unclear. This study aims to use computational modelling to generate hypotheses about semaglutide's long‐term metabolic (body weight, net energy intake, blood glucose ...
