vesikulaarien
Vesikulaarien is a Finnish term used in biology to describe vesicles or vesicle-related structures. In cellular biology, vesicles are small, membrane-bound sacs that transport, store, or process molecules. They range in size from tens to hundreds of nanometers and are formed by budding from donor membranes such as the plasma membrane, endoplasmic reticulum, or Golgi apparatus. The process often involves coat protein complexes—COPII mediates ER to Golgi traffic, COPI governs retrograde transport, and clathrin participates in endocytosis and Golgi-to-endosome routes.
The contents of vesicles are selectively loaded and protected by lipid bilayers and associated proteins. Vesicular
Fusion of vesicles with their targets is directed by Rab GTPases and SNARE proteins, which ensure accurate
Disruptions of vesicular trafficking can contribute to diseases such as lysosomal storage disorders, neurodegenerative diseases, and
