Vesicular trafficking is a cellular process that involves the movement of small membrane-bound sacs, called vesicles, within a cell. These vesicles transport proteins, lipids, and other molecules to different locations, ensuring that essential materials reach their intended destinations. This process is crucial for maintaining cellular functions, such as secretion, nutrient uptake, and membrane repair. The trafficking of vesicles is facilitated by various proteins, including motor proteins that move along cytoskeletal tracks. Additionally, vesicles can fuse with other membranes, allowing for the exchange of materials. Proper vesicular trafficking is vital for cell health and function, and disruptions can lead to diseases.
