Project description
Role of glial cells tanycytes in healthy ageing
The organisms' survival depends on energy homeostasis, involving the control of neuroendocrine functions that integrate metabolic feedback. Tanycytes are glial cells lining the floor of the third ventricle in the median eminence of the hypothalamus which control the secretion of neuropeptides by hypothalamic neurons into the pituitary portal circulation and regulate blood-brain and blood-cerebrospinal fluid exchanges. Tanycytes actively shuttle metabolic signals to hypothalamic neurons that control food intake. The goal of the EU-funded WATCH project is to employ state-of-the-art technologies in systems neuroscience, mouse genetics, and translational research, to elucidate the role of tanycytes and provide new directions in biomarker research and therapeutic approaches for a variety of disorders that impair healthy ageing.
Objective
The survival of an organism depends on energy homeostasis, involving the control of neuroendocrine functions that integrate metabolic feedback and adapt the response of the organism to physiological demands. Tanycytes, specialized glial cells lining the floor of the third ventricle in the median eminence of the hypothalamus, act as linchpins of these processes, dynamically controlling the secretion of neuropeptides by hypothalamic neurons into the pituitary portal circulation and regulating blood-brain and blood-cerebrospinal fluid exchanges, both processes that depend on their morphological plasticity in response to the physiological state. In addition to their barrier properties, they actively shuttle circulating metabolic signals to hypothalamic neurons that control food intake. The overarching goal of WATCH is to synergistically employ state-of-the-art technologies in systems neuroscience, mouse genetics and bench-to-bedside research, to explore the role of these unique and versatile cells, providing new directions in biomarker research and new therapeutic approaches for a variety of disorders that impair well-aging. Our specific aims are:
1. Genetic dissection of the in vivo regulation, pathophysiological function and molecular markers of tanycytes classified according to their anatomical location.
2. Identification of novel heterogeneous, molecularly distinct tanycytes and associated endothelial cells and determining how these characteristics evolve under distinct physiological and pathological conditions.
3. Functional validation of newly classified subgroups of tanycytes and the specific modulation of the activity of these subgroups at the experimental level.
4. Exploration of the functional consequences of pharmacologically activating pathways required for the tanycytic shuttling of metabolic signals on their CSF levels of these factors, hypothalamic activity and cognition in animal models and patients with morbid obesity or age-related cognitive deficits.
