Membrane trafficking is a field of research that focuses on the transport of molecules and cellular components within cells, as well as between cells and organelles. This process involves the movement of proteins, lipids, and other molecules through various membranous compartments in order to maintain cellular functions, communication, and homeostasis. Membrane trafficking plays a crucial role in key cellular processes such as signal transduction, nutrient transport, and organelle biogenesis. Dysregulation of membrane trafficking has been linked to various diseases, including cancer, neurodegenerative disorders, and metabolic diseases, making it an important area of study for understanding cellular biology and developing potential therapies.
