    Traumatic lung injury (TLI) can lead to acute respiratory distress syndrome (ARDS), which has a high mortality rate and limited targeted therapies.

  • 2

    Single-cell RNA sequencing revealed that ISG15+STAT1+ monocytes expand post-trauma and drive an inflammatory response through M1-like polarization.

  • 3

    PIM1 was identified as a core pathogenic gene co-upregulated in both peripheral blood and lung tissue, confirmed as a causal risk factor for ARDS.

  • 4

    The JAK2/STAT3/PIM1 signaling pathway is activated during the acute trauma phase, contributing to the inflammatory response in TLI.

  • 5

    Fedratinib, a JAK2 inhibitor, was shown to inhibit M1 polarization and inflammatory gene expression, suggesting its potential as a therapeutic candidate for TLI.
