The Second World Congress on Targeting Extracellular Vesicles (EVs) is set to convene on October 15–16, 2025, in the vibrant city of Valencia, Spain. This groundbreaking event represents a collaborative effort between the World Mitochondria Society and the International Society of Microbiota, two leading organizations at the forefront of biomedical research. The congress promises to explore the burgeoning intersection of mitochondrial biology and microbiome science, unified through the emerging field of extracellular vesicle research. It is an unprecedented opportunity to delve into the mechanisms by which these tiny, membrane-bound particles mediate complex biological communication processes and drive innovative therapeutic strategies.
Extracellular vesicles, which include exosomes and microvesicles, have rapidly ascended from obscurity to a central focus in cell biology and medicine. Once dismissed as mere cellular debris, EVs are now recognized as critical carriers of molecular information. They transport a diverse cargo—encompassing nucleic acids, proteins, lipids, and even mitochondrial components—across cellular boundaries, facilitating intercellular signaling and remote modulation of physiological functions. These vesicles act as sophisticated biological messengers, dynamically coordinating processes ranging from immune responses to metabolic regulation and neural communication.
The theme guiding this next congress, “Bridging Two Frontiers: Mitochondria & Microbiota,” reflects an ambitious vision to unify insights into two of the most compelling biological realms. Mitochondria, the cellular powerhouses, are instrumental not only in bioenergetics but also in signaling pathways that regulate cell fate and function. Meanwhile, the microbiota—complex communities of microorganisms residing in the human body—play pivotal roles in systemic health, influencing everything from inflammation to brain function. Extracellular vesicles serve as a molecular bridge linking these domains, facilitating bidirectional communication that shapes health and disease.
Mitochondrial biology and EV research converge particularly in understanding how vesicles can carry mitochondrial DNA, proteins, and even organelle fragments. This mitochondrial cargo transported by EVs can profoundly influence recipient cells by altering their energy metabolism or stress responses. Such vesicle-mediated mitochondrial transfer has significant implications for conditions characterized by mitochondrial dysfunction, including neurodegenerative diseases, metabolic syndromes, and aging. By elucidating these pathways, researchers hope to harness EVs as both diagnostic biomarkers and vectors for targeted therapies.
Simultaneously, the microbiome-derived extracellular vesicles are gaining attention for their role as mediators of host-microbe interactions. Bacterial EVs can modulate immune responses, gut-liver communication, and even influence the gut-brain axis, impacting neurological health. These microbial vesicles carry unique molecular signatures capable of triggering inflammatory cascades or promoting homeostasis, thus representing a critical axis of interkingdom communication. Understanding this crosstalk opens new avenues for microbiota-targeted interventions in chronic diseases and immune disorders.
Dr. Marvin Edeas, President of the Mitochondria & Microbiota Task Force and Chairman of the Scientific Committee, eloquently summarizes the transformative potential of EVs. He likens them to “molecular SMS messages,” underscoring their role in transmitting biological information between distant cells and organs. This analogy captures the intricate and dynamic nature of EV-mediated communication networks that orchestrate immunity, metabolism, brain function, and aging. Despite rapid progress, many fundamental questions remain about the evolutionary origins, selection, and regulatory mechanisms governing EV cargo packaging and release.
Decoding the molecular “language” of EVs stands as a paramount challenge with far-reaching implications. Unlocking the mechanisms by which cells control EV content and targeting could revolutionize precision medicine. EVs are poised to redefine diagnostics as non-invasive biomarkers capable of revealing disease states at early stages. Moreover, by engineering EVs to deliver therapeutic molecules selectively, researchers envision novel treatments that minimize off-target effects and enhance efficacy. This frontier exemplifies the convergence of basic science, biotechnology, and clinical innovation.
The congress program has been meticulously designed to foster deep scientific engagement with sessions spanning fundamental biology to translational research. Participants will benefit from keynote lectures delivered by eminent scientists, thematic discussions on bioenergetics, microbiota-host interactions, and clinical applications. The inclusion of sessions focused on oxidative stress, retinal and metabolic diseases, and inflammatory pathways underscores the broad relevance of EV science across biomedical disciplines. Additionally, attention to regulatory and commercial aspects aims to catalyze the translation of EV technologies from bench to bedside.
Of particular note is the dedicated Start-up / Industry & Investor Showcase embedded within the program. This innovative forum will present emerging biotech companies pioneering EV-based therapeutics and diagnostics. By facilitating dialogue between academia, industry, and investors, the congress aims to accelerate technology development and commercialization, thereby amplifying the impact of extracellular vesicle research on healthcare. Such integration highlights the strategic importance of EVs as a platform technology with vast potential across multiple sectors.
Attendees can expect rich interdisciplinary interactions empowered by the congress’s collaborative ethos. The integration of mitochondrial medicine and microbiota research within the EV framework represents a paradigm shift toward understanding human health as a networked system. The event will also address standardization challenges in EV isolation, characterization, and clinical implementation, critical for advancing the field’s reproducibility and regulatory acceptance. Collective efforts in these domains will underpin the future of EV-based diagnostics and therapeutics.
The location of the congress, Valencia, Spain, offers an inspiring setting for this international scientific exchange. Known for its vibrant research community and innovative biotech landscape, Valencia provides an ideal backdrop for fostering collaborations that will shape the next decade of extracellular vesicle science. The congress is open to researchers, clinicians, industry leaders, media, and institutional stakeholders, creating a dynamic environment for knowledge dissemination, partnership formation, and strategic networking.
Media representatives seeking in-depth coverage or interviews with key thought leaders are encouraged to connect with the organizers for exclusive access. The conference also serves as a platform to promote awareness of EV science’s transformative implications for medicine, lifestyle, and society at large. As extracellular vesicles emerge from obscurity to center stage, the event will spotlight their potential to revolutionize our understanding of biology and unlock novel therapeutic frontiers.
In summary, the Second World Congress on Targeting Extracellular Vesicles is poised to be a landmark event, uniting diverse disciplines around one of the most exciting scientific developments of our time. As EV research continues to unravel the complexities of intercellular communication and bioactive cargo transfer, the knowledge generated here will pave the way toward innovative diagnostics and therapies. This congress represents a critical nexus where mitochondrial biology, microbiota science, and vesicle technology converge to shape the medicine of tomorrow.
