    Collapse Overview
    Dr. Maretti-Garcia's research focuses on uncovering how the immune system contributes to the progression of chronic liver diseases. She specializes in advanced transcriptomic analyses and real-time cellular behavior assays, leveraging these technologies to explore the molecular and cellular mechanisms driving liver dysfunction.
    She has developed an innovative in vitro model for MASLD using 3D human liver spheroids, integrating single-cell transcriptomics and epigenetics to investigate how environmental pollutants like PFAS influence the progression of MASLD and hepatocellular carcinoma (HCC). In addition to environmental factors, she is also exploring the role of dietary factors, such as cholesterol and sugar, in the onset of MASLD, aiming to uncover new strategies for prevention and treatment.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication.
