What is the function of Nfkb?
NF-κB plays a key role in regulating the immune response to infection. 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.
What is NF kappa?
Nuclear factor kappa B (NF-κB) is an ancient protein transcription factor (Salminen et al., 2008) and considered a regulator of innate immunity (Baltimore, 2009). The NF-κB signaling pathway links pathogenic signals and cellular danger signals thus organizing cellular resistance to invading pathogens.
What is the role of NFKB in inflammation and cancer?
NFκB is an important signaling pathway that is involved extensively in cancer development and progression. Through controlling the expression of target genes, such as TNFA, IL6, BCLXL, BCL2, BCLXS, XIAP, and VEGF, NFκB mediates tumor-cell proliferation, survival, and angiogenesis.
How is NF KB regulated?
The primary mechanism for regulating NF-κB is through inhibitory IκB proteins (IκB, inhibitor of NF-κB), and the kinase that phosphorylates IκBs, namely, the IκB kinase (IKK) complex.
Who discovered NF kB?
Ranjan Sen
Following the discovery of NF-κB by Ranjan Sen in 1986 (1), a number of postdoctoral fellows in the laboratory were pursuing the biology of this transcription factor (Michael Lenardo, Patrick Baeuerle, Gary Nabel, and Jaqueline Pierce).
How do you measure NF KB activation?
Another common method to measure NF-κB activity at the transcriptional activation level is to use a gene reporter assay, which introduces an exogenous NF-κB consensus promoter sequence linked to a measurable ‘reporter gene’ such as luciferase (18).
What genes does NF KB regulate?
NF-κB induces the expression of various pro-inflammatory genes, including those encoding cytokines and chemokines, and also participates in inflammasome regulation. In addition, NF-κB plays a critical role in regulating the survival, activation and differentiation of innate immune cells and inflammatory T cells.
What stimulates Nfkb?
The primary mechanism for canonical NF-κB activation is the inducible degradation of IκBα triggered through its site-specific phosphorylation by a multi-subunit IκB kinase (IKK) complex.

What is the role of nfnf-кb in inflammatory response?
NF-кB changes cell behavior in many ways; it regulates the transcription of large number of genes, especially those involved in immune and inflammatory responses and thus has a role in regulating inflammation, cell proliferation and apoptosis [64, 67].
What is the major challenge for future research on NFkB gene regulation?
The comp lete understanding of NFkB gene regulation is the refore a major challenge for future research. 1. Aggarwal B.B. (2003). Signalling pathway s of the TNF superfamily.
How is NFkB activated by cytokines?
A: NFkB can be activated by a variety of stimuli, including cytokines (such as TNF and IL-1), T and B cell mitogens, viral proteins, and stress inducers (such as reactive oxygen species or UV radiation). In the cytoplasm, NFkB is inhibited by IKB. Upstream activating signal may cause phosphorylation of IkB by IKK (IkB kinase).
