Control of ingestion by the caudal brainstem
The passage of food through the alimentary canal generates a series of feedback signals that are sensed by the brain and used to control behavior. Many of these signals converge on the caudal brainstem, which contains the key neural circuits that drive meal termination.I will describe our work investigating the dynamics and function of these circuits during ingestion. A central theme is that these circuits integrate layers of signals from the mouth and gut, both during ingestion and over longer timescales through learning. [mehr]

The Metabolic Mosaic: Illuminating the Interplay of Diet, Microbiome, Brain and Metabolism
A balanced intake of nutrients is a key determinant of health, wellbeing, and aging. To maintain homeostasis, animals adapt their foraging strategies, physiology, and metabolism to meet immediate and future demands. We aim to understand how animals decide what to eat and how their metabolism aligns with physiological needs, focusing on the interplay between brain-body interactions, metabolic processes, and the microbiome, a key player in shaping these adaptations. Our research uses Drosophila melanogaster as a model to investigate nutritional decision-making at the interface of behavior, metabolism, microbiome, and physiology. By leveraging tools such as automated behavioral analyses, metabolomics, connectomics, neuronal activity imaging, and precise nutritional and microbial manipulations, we explore how internal states and environmental factors influence dietary choices and metabolic responses. This integrative approach allows us to reveal how internal states and environmental contexts shape dietary decisions. Ultimately, our goal is to build a unified framework for understanding the principles of nutrient regulation, offering insights into metabolic resilience and fitness across species. [mehr]

Neuronal Circuits Controlling Energy Metabolism Beyond Appetite Regulation
  • Datum: 14.11.2025
  • Uhrzeit: 10:00 - 11:00
  • Vortragender: Giuseppe D'Agostino, PhD
  • Giuseppe (Peppe) D'Agostino is a Group Leader at the University of Manchester, Division of Diabetes, Endocrinology and Gastroenterology, and he is a member of the Lydia Becker Institute of Immunology and Inflammation and the Geoffrey Jefferson Brain Research Centre. A pharmacologist by training, Peppe earned his PhD in Neuropharmacology from the University of Naples, Italy, and pursued further research training at Yale University (USA), the University of Cambridge, and the University of Aberdeen. In 2017, he was awarded a Medical Research Council fellowship to establish his independent research group. In 2019, his laboratory relocated to the University of Manchester In 2019, where in 2023 became Senior Lecturer (Associate Professor). His group focuses on neuronal circuits that control appetite and fuel metabolism under both homeostatic and pathological conditions, employing genetics, systems neuroscience, and integrative physiology approaches.

Brain circuits that sense energy do far more than drive appetite. This talk explores how hypothalamic and brainstem networks orchestrate whole-body metabolism, managing a critical trade-off between immune readiness and energy conservation. This highlights an emerging framework of how the brain dynamically matches whole-body physiology to its perceived energy status and prioritizes tissue maintenance under changing nutritional states.

Unlocking Brain Pathways to Treat Metabolic Disease
Metabolic diseases such as obesity and type-2 diabetes (T2D) are among the most pressing health challenges of our time. Affecting over one-third of the world’s population, they are projected to become the leading cause of mortality by 2030. Discovering effective treatments is a global health priority.While long regarded as disorders of peripheral organs, mounting evidence reveals that the brain plays a central role in their development and progression. This seminar will explore how neural circuits regulate energy balance, glucose homeostasis, and insulin sensitivity, highlighting the dynamic two-way communication between the brain and peripheral tissues.Drawing on recent discoveries from AProf Dodd’s laboratory, we will examine how specific brain pathways act as potential therapeutic targets. By understanding and harnessing these mechanisms, new opportunities emerge to design treatments that more effectively combat obesity and T2D. [mehr]

A hypothalamic circuit that modulates feeding and parenting behaviours
Across mammalian species, new mothers undergo behavioural changes to nurture their offspring and meet the caloric demands of milk production. Although many neural circuits underlying feeding and parenting behaviours are well characterized, it is unclear how these different circuits interact and adapt during lactation. Here we performed transcriptomic profiling of the arcuate nucleus (ARC) and the medial preoptic area (MPOA) of the mouse hypothalamus in response to lactation and hunger. Furthermore, we showed that heightened appetite in lactating mice was accompanied by increased activity of hunger-promoting agouti-related peptide (AgRP) neurons in the ARC (ARCAgRP neurons). To assess the strength of hunger versus maternal drives, we designed a conflict assay in which female mice chose between a food source or pups and nesting material. Although food-deprived lactating mothers prioritized parenting over feeding, hunger reduced the duration and disrupted the sequences of parenting behaviours in both lactating and virgin females. We found that ARCAgRP neurons inhibit bombesin receptor subtype 3 (BRS3) neurons in the MPOA (MPOABRS3 neurons), which become more active postpartum and govern parenting and satiety. Activation of this ARCAgRP-to-MPOABRS3 circuit shifted behaviours from parenting to food-seeking. Thus, hypothalamic networks are modulated by physiological states and work antagonistically during the prioritization of competing motivated behaviours. [mehr]
