Furthermore, Wen introduced a novel diagnostic and prognostic approach for cholangiocarcinoma using exosomal circRNA signatures, which could facilitate early detection and monitoring of this aggressive cancer (ref: Wen doi.org/10.1038/s41392-024-01814-3/). Collectively, these studies underscore the multifaceted roles of EVs in cancer therapy, from targeted delivery to biomarker discovery, while also highlighting the need for further exploration of their mechanisms and applications in clinical settings.

The utilization of extracellular vesicles (EVs) in disease monitoring has gained traction, particularly in the context of cancer and infectious diseases. Wen's study on cholangiocarcinoma demonstrated the potential of exosomal circRNA as a biomarker for diagnosis and monitoring of early recurrence, showcasing the ability of EVs to provide critical insights into disease progression through liquid biopsies (ref: Wen doi.org/10.1038/s41392-024-01814-3/). In the realm of infectious diseases, DeMarino's research revealed that HIV-1 RNA present in EVs correlates with neurocognitive outcomes in HIV-positive individuals, suggesting that EVs could serve as valuable indicators of disease status and progression (ref: DeMarino doi.org/10.1038/s41467-024-48644-z/). Additionally, the findings by Li regarding circTRIM1's role in promoting chemoresistance and metastasis in triple-negative breast cancer highlight the potential of EVs in monitoring treatment responses and disease dynamics (ref: Li doi.org/10.1186/s12943-024-02019-6/). These studies collectively emphasize the transformative potential of EVs in enhancing disease monitoring, offering novel avenues for early detection and personalized treatment strategies.

Understanding the mechanisms underlying extracellular vesicle (EV) function is crucial for harnessing their therapeutic potential. Wiklander's research on antibody-displaying EVs elucidates how these vesicles can be engineered to deliver therapeutic agents specifically to target tissues, thereby enhancing treatment efficacy (ref: Wiklander doi.org/10.1038/s41551-024-01214-6/). This modular approach allows for the customization of EVs based on the desired therapeutic context. Additionally, Yu's investigation into the role of exosomes in osteosarcoma metastasis revealed that these vesicles can transfer specific microRNAs that modulate tumor behavior, indicating a complex interplay between primary tumors and metastatic sites (ref: Yu doi.org/10.1016/j.apsb.2024.01.016/). Furthermore, DeMarino's findings on HIV-1 RNA in EVs suggest that these vesicles may play a role in the pathophysiology of neurocognitive disorders associated with HIV, highlighting their potential as biomarkers and therapeutic targets (ref: DeMarino doi.org/10.1038/s41467-024-48644-z/). Collectively, these studies provide insights into the diverse functions of EVs, emphasizing their roles in targeted therapy, intercellular communication, and disease progression.

Extracellular vesicles (EVs) play a pivotal role in modulating immune responses, particularly in inflammatory conditions. Kang's research demonstrated that neutrophil-derived EVs can communicate with macrophages to promote itaconate accumulation, which subsequently ameliorates cytokine storm syndrome, a severe inflammatory response (ref: Kang doi.org/10.1038/s41423-024-01174-6/). This highlights the potential of EVs in mediating intercellular communication during immune responses. In a related study, Wang explored the role of PAD4 in inflammatory bowel disease, revealing that neutrophil-derived EVs contribute to mucosal inflammation through citrullination processes (ref: Wang doi.org/10.1038/s41423-024-01158-6/). These findings underscore the complexity of EV-mediated immune modulation and suggest that targeting EVs may offer therapeutic strategies for managing inflammatory diseases. Furthermore, the involvement of EVs in the transfer of signaling molecules between immune cells emphasizes their importance in orchestrating immune responses and maintaining homeostasis.

Extracellular vesicles (EVs) have emerged as critical players in the wound healing process, facilitating communication between cells and promoting tissue regeneration. Research by Kang highlighted the role of neutrophil-derived EVs in modulating macrophage activity, which is essential for effective wound healing and resolution of inflammation (ref: Kang doi.org/10.1038/s41423-024-01174-6/). This interplay between neutrophils and macrophages via EVs underscores the importance of these vesicles in coordinating the immune response during tissue repair. Additionally, Yu's study on exosomes derived from metastatic sites in osteosarcoma suggests that these vesicles may influence the wound healing environment by transferring specific microRNAs that affect cellular behavior (ref: Yu doi.org/10.1016/j.apsb.2024.01.016/). The findings collectively indicate that EVs not only serve as carriers of therapeutic agents but also actively participate in the biological processes that govern wound healing, making them potential targets for enhancing regenerative medicine strategies.

Extracellular vesicles (EVs) are increasingly recognized for their roles in neurological disorders, particularly in the context of HIV and neurocognitive outcomes.
