Abstract
Promyelocytic leukemia nuclear bodies (PML-NBs) are dynamic membrane-less organelles (MLOs) located in the nucleus that serve as regulatory hubs for multiple cellular processes. This review examines current understanding of PML-NB structure, assembly mechanisms, and their diverse functional roles. We discuss how PML-NBs interact with chromatin to influence gene expression, regulate transcription factors, and participate in protein quality control. The review highlights their critical functions in tumor suppression, particularly in acute promyelocytic leukemia, and their role in intrinsic antiviral defense against various pathogens. Despite significant advances in the field, key questions remain regarding the mechanistic triggers of PML-NB formation and their common roles across different pathologies. Further elucidation of these aspects may provide valuable insights for developing therapeutic approaches targeting the PML-NB axis in disease treatment.

期刊介绍：
Biomolecules (ISSN 2218-273X) is an international, peer-reviewed open access journal focusing on biogenic substances and their biological functions, structures, interactions with other molecules, and their microenvironment as well as biological systems. Biomolecules publishes reviews, regular research papers and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced.
