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.
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 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.
