Foundations of Extracellular Vesicles in Health and Disease

Extracellular vesicles (EVs) have revolutionized our understanding of cell-to-cell communication, transitioning from biological waste disposers to critical messengers in health and disease. Understanding how these tiny vesicles influence physiological processes and drive disease progression is essential for anyone entering the fields of modern biology, medicine, or biotechnology. This written course provides a comprehensive introduction to the biology of extracellular vesicles, including exosomes and microvesicles. You will explore their biogenesis, molecular cargo, and physiological functions, as well as their critical roles in pathologies like cancer, cardiovascular diseases, and neurodegeneration. By the end of this course, you will understand how EVs are isolated, characterized, and utilized in cutting-edge diagnostics and therapeutic applications. What you'll learn: - Understand the fundamental biology, classification, and biogenesis of extracellular vesicles. - Explore how EVs facilitate intercellular communication by transporting proteins, lipids, and nucleic acids. - Analyze the role of EVs in maintaining normal physiology and driving disease progression. - Learn standard methods for EV isolation and characterization in alignment with modern scientific guidelines. - Investigate the clinical potential of EVs as biomarkers in liquid biopsies and as vehicles for targeted drug delivery. The journey begins with core biological concepts and nomenclature, establishing a solid scientific foundation before moving into physiological mechanisms. From there, you will read about the latest laboratory techniques, clinical applications, and future research directions. This course is designed for students, researchers, and healthcare professionals seeking a clear, beginner-friendly entry point into vesicle biology, with no advanced prior knowledge required.
