Nuclear factor kappa B-mediated C-reactive protein transcriptional pathway (NF-κB-CRP pathway)

The Nuclear factor kappa B (NF-κB)-mediated C-reactive protein (CRP) transcriptional pathway is a critical signaling sequence responsible for the hepatic production of CRP during the acute-phase response (Agrawal et al., 2001, Frontiers in Immunology). Triggered by pro-inflammatory cytokines such as Interleukin-1 beta (IL-1β) and Tumor Necrosis Factor alpha (TNF-α), the pathway involves the activation and nuclear translocation of NF-κB transcription factor subunits, which then bind to the promoter region of the CRP gene (Kramer et al., 2008, Molecular Biology of the Cell). This binding often occurs in coordination with other transcription factors like C/EBPβ to drive high-level expression of CRP, a key clinical biomarker of systemic inflammation (NIH/PubMed). Dysregulation of this pathway is a central feature in chronic inflammatory states, contributing to the pathogenesis of cardiovascular diseases, rheumatoid arthritis, and metabolic disorders (StatPearls). While the pathway itself is not a single drug target, its components—including upstream cytokine receptors and the NF-κB complex—are major focal points for anti-inflammatory therapeutics such as corticosteroids and biologics (PubChem).
