Cajal Bodies

Cajal Bodies are small, specialized structures inside the nucleus of a cell, acting like tiny processing centers. They play a key role in assembling and modifying components needed for gene expression, especially those involved in producing certain types of RNA and proteins. By organizing these processes efficiently, Cajal Bodies help ensure that cells function properly and respond quickly to changes. Named after the scientist Santiago Ramón y Cajal, these structures are important for maintaining healthy cell activity and are especially active in cells with high levels of gene production, such as nerve and immune cells.
