Autoinflammation: Interferonopathies and Other Autoinflammatory Diseases

Area of Science:

• Immunology
• Genetics
• Dermatology

Background:

• Autoinflammatory diseases (AIDs) are a growing group of over 40 genetically defined disorders.
• A hallmark of AIDs is a dysregulated innate immune response, often presenting with overlapping clinical and dermatological features.
• Autoinflammatory pathways are increasingly recognized in common conditions like psoriasis and in other immune disorders.

Purpose of the Study:

• To review the expanding landscape of autoinflammatory diseases.
• To discuss the commonalities between AIDs, dermatological conditions, and other immune disorders.
• To highlight the significance of acquired AIDs driven by somatic mutations.

Main Methods:

• Literature review of autoinflammatory diseases.
• Analysis of clinical and genetic data.
• Discussion of emerging concepts in innate immune dysregulation.

Main Results:

• The number of identified AIDs exceeds 40, with significant overlap in clinical presentation.
• Dermatological manifestations are common in AIDs and autoinflammatory features are seen in psoriasis.
• Somatic mutations in myeloid cells represent a novel cause of acquired AIDs.

Conclusions:

• The understanding of autoinflammatory diseases is rapidly evolving.
• Acquired AIDs due to somatic mutations signify a new era in the field.
• Interdisciplinary approaches are crucial for diagnosing and managing AIDs.
