Title : Novel exosomal biomarkers for MASH


Metabolic Dysfunction-Associated Steatohepatitis (MASH), a subset of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), has emerged as a significant public health concern worldwide. MASH is characterized by hepatic inflammation, which can lead to fibrosis, cirrhosis, and even hepatocellular carcinoma. Identifying reliable biomarkers for MASH has become a pivotal focus in the medical field, as they hold the potential to revolutionize both diagnosis and management of the disease.

One of the primary challenges in diagnosing MASH is its asymptomatic nature in the early stages. Currently, liver biopsy remains the gold standard for diagnosis, but it is invasive and associated with various risks. Biomarkers offer a non-invasive and more accessible alternative. The need for accurate, non-invasive diagnostic and prognostic tools has led to the exploration of novel biomarkers, with a recent focus on exosomes.

Exosomes, small extracellular vesicles secreted by various cell types, have gained recognition as potential biomarkers in MASH. These nanoscale vesicles encapsulate a diverse cargo of bioactive molecules, including proteins, lipids, and nucleic acids, reflecting the state of the parent cells. This unique composition makes exosomes promising candidates for capturing the intricate molecular changes that occur in MASH.

Exosomes have been investigated for their role in mediating inflammation, fibrogenesis, and lipid metabolism, all of which are key processes in MASH pathogenesis. They may serve as indicators of disease severity and progression. Additionally, exosomal miRNAs, which can regulate gene expression, have shown promise as specific biomarkers for MASH, capable of distinguishing it from simple steatosis.

The emerging role of exosomes as innovative biomarkers in MASH is on the horizon. Their potential as non-invasive, highly sensitive, and specific indicators of disease presence and progression underscores their significance in the ongoing efforts to combat MASH. Further research and validation are essential to fully unlock the diagnostic and prognostic potential of exosomes in MASH management.

Dr. Leszczynska, who completed her PhD in Regenerative Medicine at the National University of Galway in Ireland, currently serves as the Scientific Lead at the University of California San Diego, California, within Prof. Feldstein's lab, a role she has held since 2018. Her work primarily involves overseeing diverse, interdisciplinary teams with a special focus on liver disease, novel biomarker discovery, and therapeutic strategies for MASH. During her time at Cedars-Sinai Medical Center, she supervised teams and conducted research on exosomes, eye stem cells, and microRNA expression in diabetic corneas. Notably, her role as the Principal Investigator of an NIA award at Johns Hopkins School of Medicine from 2013 to 2016 was marked by significant contributions to aging studies and startup initiatives. Dr. Leszczynska is deeply committed to advancing medical knowledge and making pioneering contributions to the field of research.
