- Nucleofactor ⁇ B is a cytokinin (TNF-a, IL-1 ⁇ , IL-6, etc.), chemokine (RANTES, IL-8, etc.), or arachidonic acid metabolizing enzyme It is a ubiquitous transcription factor that activates the transcription and translation of proteins that contribute to inflammatory reactions such as (COX-2) and is important for acute and chronic inflammatory reactions in inflammatory diseases or autoimmune diseases. (Mol. Cell Biol. 1999; 19: 4547-51) 0 For example, in synovial cells of patients with rheumatoid arthritis (RA), NF- ⁇ B translocates into the nucleus and is activated.
