Monogenic disorders of the TNF signalling pathway

Area of Science:

• Immunology
• Molecular Biology
• Genetics

Background:

• Tumor Necrosis Factor (TNF) is a key regulator of immune responses, inflammation, and cell death.
• Proper TNF signaling is vital for maintaining tissue and immune homeostasis.
• Abnormal TNF signaling is linked to numerous physiological and pathological conditions.

Purpose of the Study:

• To explore the molecular mechanisms underlying rare monogenic disorders caused by TNF pathway dysregulation.
• To understand how defects in TNF signaling contribute to autoinflammatory syndromes, immunodeficiencies, autoimmune diseases, and neurodegenerative conditions.
• To highlight the importance of tightly regulated TNF signaling for immune balance.

Main Methods:

• Analysis of monogenic disorders affecting core TNF pathway components.
• Investigation of molecular defects leading to abnormal TNF signaling.
• Examination of pathway integration and tissue-specific gene expression.
• Study of post-translational modifications and cell-death regulators in disease pathogenesis.

Main Results:

• Dysregulation of TNF signaling underlies a spectrum of rare diseases, including autoinflammatory, immunodeficiency, autoimmune, and neurodegenerative conditions.
• Distinct molecular defects can result in overlapping clinical phenotypes, emphasizing shared pathogenic mechanisms.
• Pathway integration and tissue-specific gene expression influence disease presentation.
• Disruptions in post-translational modifications and cell-death regulation are central to TNF-mediated pathology.

Conclusions:

• Monogenic disorders of the TNF pathway offer critical insights into TNF-mediated inflammation and cell death.
• Precise genetic and mechanistic understanding of TNF signaling is essential for diagnosing and treating these rare conditions.
• Targeting TNF dysregulation holds therapeutic potential for a range of immune-related and neurological disorders.
