Scientists at King Abdullah University of Science and Technology (KAUST) have discovered that astrocytes, a type of non-neuronal cell, actively influence communication between neurons and processes linked to learning and memory. Their study, published in The Journal of Physiology, revealed that lactate not only provides energy to neurons but also triggers a signaling pathway within them, challenging the traditional view of astrocytes as passive support cells. This research, conducted largely at KAUST with international collaboration from Italy and Switzerland, provides new insights into the molecular mechanisms supporting brain cell communication and synaptic plasticity. Why it matters: These findings are significant for understanding fundamental brain science and could open new avenues for therapeutic strategies targeting neurological disorders and memory loss.
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'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 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 researcher Corrado Calì won an award at the Brainstorming Research Assembly for Young Neuroscientists (BraYn) in Italy for his work on glycogen modulation and synapse stabilization. Calì presented research in collaboration with KAUST Professor Andrea Falqui and Dr. Elena Vezzoli from the University of Milan, investigating the lactate shuttle's involvement in synaptic plasticity. Calì and KAUST colleagues are also collaborating with the Blue Brain Project to produce a computer simulation of astrocyte-neuron coupling, using 3D virtual reality to investigate brain cell morphologies at the nanoscale. Why it matters: This award recognizes KAUST's contribution to neuroscience research and highlights the university's collaborative efforts in understanding brain plasticity and developing advanced tools for studying brain structures.
