    CARS2 suppression in THP-1 macrophages leads to a pro-inflammatory expression profile associated with increased interferon signaling.

  • 2

    Reduced CARS2 levels do not significantly activate STAT1 or NF-κB phosphorylation, indicating a unique inflammatory response.

  • 3

    CARS2 suppression results in decreased reactive oxygen species levels without affecting mitochondrial function or integrity.

  • 4

    The study suggests that CARS2 has an anti-inflammatory role in macrophages that extends beyond its mitochondrial functions.

  • 5

    CARS2 suppression creates an atypical inflamed environment in unpolarized macrophages, highlighting its importance in immune regulation.
