The activation of inflammatory signaling pathways leads to the production and release of cytokines, chemokines, and other effector molecules that recruit and activate immune cells. The nuclear factor kappa B (NF-κB) is a critical transcription factor that regulates the expression of multiple genes involved in inflammation, immunity, cell survival, and proliferation. The dysregulation of NF-κB signaling is implicated in the pathophysiology of various inflammatory diseases, including rheumatoid arthritis, inflammatory bowel disease, psoriasis, and sepsis.The activation of NF-κB involves the signal-induced degradation of IκBα, the inhibitor of NF-κB, and the nuclear translocation of the NF-κB dimers, including p65/p50, p65/c-Rel, and RelB/p50. The activation of the IκB kinase (IKK) complex, composed of IKKα, IKKβ, and NEMO, is a critical step in this process. IKKβ is considered the primary kinase that phosphorylates IκBα, leading to its ubiquitination and subsequent proteasomal degradation.IKIP, also known as the inhibitor of kappa B phosphorylation, is a small protein that binds to the IKK complex and inhibits its activity. IKIP has been shown to negatively regulate the activation of NF-κB and the expression of NF-κB target genes, including TNFα, IL-1β, COX-2, and iNOS. IKIP expression levels are decreased in inflamed tissues from patients with inflammatory diseases, suggesting that IKIP deficiency may contribute to NF-κB hyperactivation and inflammation.We hypothesize that th...
