Biophysical aspects of migrasome organelle formation and their diverse cellular functions
The transient cellular organelles known as migrasomes, which form during cell migration along retraction fibers, have emerged as a crutial factor in various fundamental cellular processes and pathologies. These membrane vesicles originate from local membrane swellings, encapsulate specific cytoplasmic content, and are eventually released to the extracellular environment or taken up by recipient cells. Migrasome biogenesis entails a sequential membrane remodeling process involving a complex interplay between various molecular factors such as tetraspanin proteins, and mechanical properties like membrane tension and bending rigidity. In this review, we summarize recent studies exploring the mechanism of migrasome formation. We emphasize how physical forces, together with molecular factors, shape migrasome biogenesis, and detail the involvement of migrasomes in various cellular processes and pathologies. A comprehensive understanding of the exact mechanism underlying migrasome formation and the identification of key molecules involved hold promise for advancing their therapeutic and diagnostic applications.
期刊介绍:
molecular – cellular – biomedical – physiology – translational research – systems - hypotheses encouraged
BioEssays is a peer-reviewed, review-and-discussion journal. Our aims are to publish novel insights, forward-looking reviews and commentaries in contemporary biology with a molecular, genetic, cellular, or physiological dimension, and serve as a discussion forum for new ideas in these areas. An additional goal is to encourage transdisciplinarity and integrative biology in the context of organismal studies, systems approaches, through to ecosystems, where appropriate.
