The role of extracellular vesicles in iron homeostasis and ferroptosis: Focus on musculoskeletal diseases.
Iron homeostasis is crucial for maintaining proper cellular function, and its disruption is considered one of the pathogenic mechanisms underlying musculoskeletal diseases. Under conditions of oxidative stress, the accumulation of cellular iron overload and lipid peroxidation can lead to ferroptosis. Extracellular vesicles (EVs), serving as mediators in the cell‐to‐cell communication, play an important role in regulating the outcome of cell ferroptosis. Growing evidence has proven that EV biogenesis and secretion are tightly associated with cellular iron export. Furthermore, different sources of EVs deliver diverse cargoes to bring about phenotypic changes in the recipient cells, either activating or inhibiting ferroptosis. Thus, delivering therapies targeting ferroptosis through EVs may hold significant potential for treating musculoskeletal diseases. This review aims to summarize current knowledge on the role of EVs in iron homeostasis and ferroptosis, as well as their therapeutic applications in musculoskeletal diseases, and thereby provide valuable insights for both research and clinical practice.
期刊介绍:
Traffic encourages and facilitates the publication of papers in any field relating to intracellular transport in health and disease. Traffic papers span disciplines such as developmental biology, neuroscience, innate and adaptive immunity, epithelial cell biology, intracellular pathogens and host-pathogen interactions, among others using any eukaryotic model system. Areas of particular interest include protein, nucleic acid and lipid traffic, molecular motors, intracellular pathogens, intracellular proteolysis, nuclear import and export, cytokinesis and the cell cycle, the interface between signaling and trafficking or localization, protein translocation, the cell biology of adaptive an innate immunity, organelle biogenesis, metabolism, cell polarity and organization, and organelle movement.
All aspects of the structural, molecular biology, biochemistry, genetics, morphology, intracellular signaling and relationship to hereditary or infectious diseases will be covered. Manuscripts must provide a clear conceptual or mechanistic advance. The editors will reject papers that require major changes, including addition of significant experimental data or other significant revision.
Traffic will consider manuscripts of any length, but encourages authors to limit their papers to 16 typeset pages or less.
