TNF receptor signalling in autoinflammatory diseases

Area of Science:

• Immunology
• Genetics
• Molecular Biology

Background:

• Autoinflammatory syndromes are characterized by recurrent inflammation due to innate immune system defects.
• Many of these disorders stem from dysregulation of the tumor necrosis factor receptor (TNFR) signaling pathway.
• This pathway dysregulation leads to increased inflammatory cytokine production.

Purpose of the Study:

• To review recent advances in understanding autoinflammatory diseases linked to TNFR signaling.
• To explore the role of molecular mechanisms, including ubiquitination, in these diseases.
• To discuss current and emerging therapeutic strategies for TNFR-associated autoinflammatory conditions.

Main Methods:

• Literature review of autoinflammatory syndromes.
• Focus on diseases involving TNFR signaling pathway defects.
• Analysis of molecular mechanisms like ubiquitination and their role in inflammation.

Main Results:

• Elucidation of molecular mechanisms in diseases like HA20, ORAS, and LUBAC deficiency provides insights into TNFR signaling.
• Advances in understanding TRAPS, RELA haploinsufficiency, RIPK1-associated disorders, and X-EDA-ID are presented.
• New therapeutic approaches targeting TNFR signaling and specific modulations are emerging.

Conclusions:

• Understanding TNFR signaling pathway defects, especially ubiquitination, is crucial for autoinflammatory disease pathogenesis.
• Recent research has significantly advanced the knowledge of various TNFR-associated autoinflammatory syndromes.
• Targeted therapies, including immune-based and disease-specific modulations, offer promising treatment avenues.
