If a novel drug aims to reduce inflammation by targeting the NF-κB signaling pathway in immune cells stimulated by lipopolysaccharide (LPS), which consequence is most likely to occur?

A)Enhanced production of reactive oxygen species
B)Increased expression of cell surface receptors
C)Reduced transcription of pro-inflammatory cytokines
D)Stimulation of the inflammasome complex assembly

💡 Explanation

Blocking the NF-κB pathway inhibits the transcription of genes encoding pro-inflammatory cytokines like TNF-α and IL-6, because NF-κB acts as a key transcription factor in their expression. Therefore, cytokine production decreases, rather than alternative scenarios like enhanced ROS or inflammasome activation, which rely on different upstream mechanisms.
