Intracellular trafficking refers to the process by which proteins, lipids, and other molecules are transported within a cell to specific locations to carry out their functions. This intricate and highly regulated process involves the movement of molecules between different compartments within the cell, such as the endoplasmic reticulum, Golgi apparatus, endosomes, and lysosomes. Researchers in this field study the mechanisms and regulation of intracellular trafficking, including the roles of molecular motors, vesicles, and protein complexes in transporting molecules within the cell. They also investigate how mutations or dysregulation of intracellular trafficking pathways can lead to various diseases, such as neurodegenerative disorders, cancer, and infectious diseases. Overall, understanding intracellular trafficking is crucial for deciphering the complex communication and signaling networks within cells and uncovering potential targets for therapeutic intervention.
