    The liver captures approximately 90% of circulating Staphylococcus aureus within 4 hours of bloodstream infection.

  • 2

    Hepatocytes are the primary responders in the liver's immune defense, showing zone-specific transcriptional activation during infection.

  • 3

    Bulk RNA sequencing revealed strong induction of acute-phase and interferon-associated genes shortly after infection.

  • 4

    The study identified Bmper as a key gene upregulated in periportal and midzonal hepatocytes during the immune response.

  • 5

    Findings suggest that liver zonation significantly influences the immune response to bloodstream infections, guiding future therapeutic strategies.
