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.
Dr. Yves Agid from the ICM Paris Institute of Translational Neuroscience lectured at KAUST's 2018 Winter Enrichment Program about the role of glial cells in brain function and behavior. He highlighted that glial cells, often overlooked in research, are crucial for neural synchronization and overall intelligence. Dysfunction of glial cells can induce pathologies like Alzheimer's and Parkinson's disease. Why it matters: The lecture underscored the importance of studying glial cells in addition to neurons for understanding and treating neurodegenerative disorders, which could influence future research directions at KAUST and in the region.
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 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.
Margaret Livingstone, a neurobiology professor at Harvard Medical School, lectured at KAUST's Winter Enrichment Program 2018 on how art can reveal insights into the human brain. She discussed how artists have long understood the independent roles of color and luminance in visual perception. Livingstone highlighted examples from Picasso, Monet, and Warhol to illustrate how artists manipulate visual cues. Why it matters: This interdisciplinary approach can potentially lead to new understandings of how the brain processes visual information and inform advances in both neuroscience and art.
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 professor Pierre Magistretti has been elected to the Norwegian Academy of Science and Letters. His election recognizes his contributions to neuroscience, specifically his work on lactate's role in brain function. Magistretti's research focuses on the lactate shuttle system and how neurons and glial cells cooperate to meet energy demands. Why it matters: This honor highlights KAUST's contribution to international neuroscience and can foster further collaboration in the field.
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.
