Article Abstract

The skeleton serves as a supportive and protective organ for the body. As individuals age, their bone tissue undergoes structural, cellular, and molecular changes, including the accumulation of senescent cells. Extracellular vesicles (EVs) play a crucial role in aging through the cellular secretome and have been found to induce or accelerate age-related dysfunction in bones and to contribute further via the circulatory system to the aging of phenotypes of other bodily systems. However, the extent of these effects and their underlying mechanisms remain unclear. Therefore, this paper attempts to give an overview of the current understanding of age-related alteration in EVs derived from bones. The role of EVs in mediating communications among bone-related cells and other body parts is discussed, and the significance of bones in the whole-body aging process is highlighted. Ultimately, it is hoped that gaining a clearer understanding of the relationship between EVs and aging mechanisms may serve as a basis for new treatment strategies for age-related degenerative diseases in the skeleton and other systems.

Integrins constitute a large and diverse family of cell adhesion molecules that play essential roles in regulating tumor cell differentiation, migration, proliferation, and neovascularization. Tumor cell-derived exosomes, a subtype of extracellular vesicles, are enriched with integrins that reflect their cells of origin. These exosomal integrins can promote extracellular matrix remodeling, immune suppression, and vascular remodeling and are closely linked to tumor progression and metastasis, acting as pivotal players in mediating organ-specific metastasis.

Forkhead-box-protein P3 (FOXP3) is a key transcription factor in T regulatory cells (Tregs). However, its expression and significance in non-immune stromal cells in the tumor microenvironment remain unclear. Here, we demonstrated FOXP3 expression in stromal fibroblasts of mouse and human gastrointestinal tumors.

Macrophages play crucial roles in the progression of liver diseases. Increasing studies have shown that mesenchymal stem cells (MSCs) and their extracellular vesicles (MSC-EVs) could reshape the liver immune microenvironment by regulating the function and phenotype of macrophages, thereby exerting a therapeutic effect on liver diseases. Mitochondria, apart from being the central hub of energy metabolism, also finely regulate macrophage-mediated innate immune responses by modulating reactive oxygen species levels, cell polarization, and cell death.
