NF-κB：Nuclear factor kappa-light-chain-enhancer of activated B cells
NF-κB（nuclear factor kappa-light-chain-enhancer of activated B cells）is a protein complex that controls transcription of DNA.
NF-κB is found in almost all animal cell types and is involved in cellular responses to stimuli such as stress, cytokines, free radicals, ultraviolet irradiation, oxidized LDL, and bacterial or viral antigens.
NF-κB plays a key role in regulating the immune response to infection（κ light chains are critical components of immunoglobulins）.
Incorrect regulation of NF-κB has been linked to cancer, inflammatory and autoimmune diseases, septic shock, viral infection, and improper immune development.
NF-κB has also been implicated in processes of synaptic plasticity and memory.
In brief, NF-κB can be understood to be a protein responsible for cytokine production and cell survival.
NF-κB was discovered by Dr. Ranjan Sen in the lab of Nobel Prize laureate David Baltimore via its interaction with an 11-base pair sequence in the immunoglobulin light-chain enhancer in B cells.
