Resumen:
Cell trafficking is a tightly regulated biological process for the exchange of signals and metabolites between cell compartments, including four main processes: membrane trafficking (transport of membrane-bound vesicles), autophagy, transport along the cytoskeleton, and membrane contact sites. These processes are cross-sectional to cellular functions, ranging from the transportation of membrane proteins, membranes, and organelles to the elimination of damaged proteins and organelles. In consequence, cell trafficking is crucial for cell survival and homeostasis, serving as a cornerstone for cellular communication and facilitating interactions both with the surrounding environment and between different organelles. Disorders of cell trafficking are clinically and pathophysiological diverse and complex and form the largest group in the recent International Classification of Inherited Metabolic Disorders (ICIMD). In this review, we explore the four categories of cell trafficking and the biological principles that drive these processes. Instead of delving profoundly into each pathway, as comprehensive reviews on those topics already exist, we offer a broad overview of the molecular mechanisms behind cell trafficking, providing a foundational understanding to ease their entry into this subject and enhance comprehension of the other articles featured in this Special Issue.
