Nuclear Factor-kappaB in Autoimmunity: Man and Mouse.

Area of Science:

• Immunology
• Molecular Biology
• Genetics

Background:

• Nuclear factor-kappa B (NF-κB) is a critical transcription complex regulating innate and adaptive immunity.
• Canonical and non-canonical NF-κB signaling pathways control immune cell functions and lymphoid organ development.

Purpose of the Study:

• To outline NF-κB signaling and regulation.
• To summarize NF-κB's role in self-tolerance mechanisms.
• To review immune defects and autoimmune diseases linked to NF-κB mutations.

Main Methods:

• Literature review of NF-κB signaling pathways.
• Analysis of molecular contributions to self-tolerance.
• Examination of genetic mutations in NF-κB pathways in mouse models and humans.

Main Results:

• NF-κB signaling is essential for immune cell activation, differentiation, survival, and lymphocyte maturation.
• Mutations in NF-κB pathways lead to immune deficiencies and autoimmune phenotypes.
• Mendelian autoimmune syndromes are associated with human NF-κB mutations.

Conclusions:

• NF-κB plays a fundamental role in maintaining self-tolerance and preventing autoimmunity.
• Understanding NF-κB pathway defects is crucial for diagnosing and potentially treating autoimmune diseases.
• Genetic variations in NF-κB signaling offer insights into both rare Mendelian and common sporadic autoimmune conditions.
