08-31-2021-1748 - Nuclear bodies (also known as nuclear domains, or nuclear dots)

 Nuclear bodies (also known as nuclear domains, or nuclear dots) are membraneless structures found in the cell nuclei of eukaryotic cells.[1] Nuclear bodies include Cajal bodies, the nucleolus, and promyelocytic leukemia protein (PML) nuclear bodies (also called PML oncogenic dots).[2] Nuclear bodies also include ND10s. ND stands for nuclear domain, and 10 refers to the number of dots seen.[3]

Nuclear bodies were first seen as prominent interchromatin structures in the nuclei of malignant or hyperstimulated animal cells[4][5] identified using anti-sp100 autoantibodies from primary biliary cirrhosis and subsequently the promyelocytic leukemia (PML) factor, but appear also to be elevated in many autoimmune and cancerous diseases.[6] Nuclear dots are metabolically stable and resistant to nuclease digestion and salt extraction.[7]

A nuclear body subtype is a clastosome suggested to be a site of protein degradation.[8]
