Interferon gamma in autoimmunity: A complicated player on a complex stage.

Area of Science:

• Immunology
• Autoimmune Diseases
• Inflammation

Background:

• Historically, Interferon gamma (IFNγ) was considered a pro-inflammatory cytokine.
• Emerging evidence reveals a more complex, dual role for IFNγ in immune responses.

Purpose of the Study:

• To review the immune modulatory activities of IFNγ.
• To summarize current evidence on IFNγ's impact on autoimmune disease pathology and regulation.

Main Methods:

• Literature review of immunological studies.
• Synthesis of data from autoimmune disease models and human pathology.

Main Results:

• IFNγ exhibits both pro-inflammatory and anti-inflammatory functions.
• The net effect of IFNγ is highly dependent on the specific physiological or pathological context.
• IFNγ significantly impacts the development and control of various autoimmune conditions.

Conclusions:

• IFNγ is a critical modulator in autoimmune diseases with context-dependent activities.
• Understanding the dual role of IFNγ is essential for developing targeted immunotherapies.
