KAUST Discovery highlights the contributions of Magistretti to the field of neuroenergetics. His research explores the cellular and molecular basis of brain energy metabolism and brain imaging. Magistretti's group discovered mechanisms underlying the coupling between neuronal activity and energy consumption, revealing the role of astrocytes. Why it matters: Understanding brain energy metabolism and the role of glial cells can advance brain imaging techniques and our understanding of neuronal processes.
KAUST researchers are exploring the link between nutrition and brain-energy metabolism to address cognitive decline, dementia, and Alzheimer’s disease. Dr. Pierre Magistretti and Dr. Johannes le Coutre are collaborating on ways to merge brain-energy metabolism research into the field of nutrition. They published an article entitled “Goals in Nutrition Science 2015-2020” in the journal Frontiers in Nutrition. Why it matters: This research could lead to nutritional interventions to hinder or prevent cognitive decline, offering a new approach beyond traditional drug treatments.
KAUST hosted the Nature Conferences: Brain Energy Metabolism in Health and Disease, convening experts to discuss brain energy use and its impact on function and disease. Researchers from KAUST and global institutions shared insights on metabolic interactions among brain cells and the brain's role in whole-body energy regulation. KAUST's President Sir Edward Byrne emphasized brain health as essential for the cognitive economy, aligning with Saudi Arabia’s Vision 2030. Why it matters: The conference highlights KAUST's growing role in global neuroscience research and its commitment to addressing critical health challenges through international collaboration.
KAUST researchers collaborated with the Blue Brain Project to study astrocytes, brain cells crucial for memory and learning. Dr. Corrado Calì produced 3D models of astrocytes using serial block-face electron microscopy to understand their structure. The study, published in Progress in Neurobiology, reveals how lactate transfer from astrocytes to neurons contributes to brain energy usage. Why it matters: Understanding astrocyte function could lead to new drugs for treating conditions like stroke and Alzheimer's disease by improving brain cell function.
KAUST and EPFL Blue Brain Project researchers propose a new theory about a 'secret language' used by cells for internal communication regarding the external world. Using a computational model, they suggest that metabolic pathways can code details about neuromodulators that stimulate energy consumption. The model focuses on astrocytes and their cooperation with neurons in fueling the brain. Why it matters: This suggests a new avenue for understanding information processing in the brain and how cells contribute to the energy efficiency of brains compared to computers.
MBZUAI researchers are developing spiking neural networks (SNNs) to emulate the energy efficiency of the human brain. Traditional deep learning models like those powering ChatGPT consume significant energy, with a single query using 3.96 watts. SNNs aim to mimic biological neurons more closely to reduce energy consumption, as the human brain uses only a fraction of the energy compared to these models. Why it matters: This research could lead to more sustainable and energy-efficient AI technologies, addressing a major challenge in deploying large-scale AI systems.
KAUST's Vice President of Research, Professor Pierre Magistretti, presented the 2023 Nansen Neuroscience Lecture in Oslo. The lecture highlighted his discovery of the astrocyte-neuron lactate shuttle and its role in brain physiology and pathology. His research explains how astrocytes feed neurons lactate as a primary energy source, impacting memory and cognition. Why it matters: The lecture recognizes KAUST's contribution to neuroscience and highlights the importance of understanding brain energy consumption for treating neurological disorders.
KAUST Discovery Professor Pierre Magistretti, Dean of KAUST's Biological and Environmental Science and Engineering Division, received an honorary membership from the Chinese Association for Physiological Sciences (CAPS). CAPS is a part of the China Association for Science and Technology, aiming to advance scientific progress and economic revitalization in China. Magistretti was recognized for his research on brain energy metabolism and the mechanisms regulating energy delivery to active neurons, with implications for functional brain imaging. Why it matters: This award highlights KAUST's growing international recognition and its faculty's contributions to fundamental research with potential applications in healthcare and neuroscience.
