Introduction
Nuclear factor kappa B (NF
B) is a rapid response transcription factor that works to ensure survival of all cells that might be subjected to environmental stress, injury, inflammation or immune reactions. NF
B activation leads to control of genes for the expression of cytokines and chemokines, immunoreceptors, cell adhesion molecules, growth factors or acute phase proteins. Thus, directly or indirectly, NF
B controls a wide variety of biological responses, in particular those that are part of innate and adaptive immunity. Cellular expression of NF
B is constitutive in B and T lymphocytes, in monocytes and neurones, or it is inducible in other cells.
NF
B structure and function
NF
B was discovered by Sen and Baltimore (1986) in mature B cells as a nuclear transcription factor, which binds to an element in the
-immunoglobin light chain enhancer. Soon it was found that NF
B occurs in most cells as an active cytoplasmic form, consisting
