Intracellular trafficking is **intracellular trafficking is** a fundamental cellular process and a major field of research that investigates the mechanisms governing the movement and sorting of molecules and organelles within cells. This tightly regulated process relies heavily on membrane dynamics, including vesicular transport, to ensure the precise delivery of diverse cargos, such as proteins and lipids, to their correct subcellular destinations, which is critical for organelle function, cellular homeostasis, and overall cellular viability.
