Interferons and interferon-related pathways in heart disease

Area of Science:

• Immunology
• Cardiovascular Science
• Molecular Biology

Background:

• Interferons (IFNs) are crucial for fighting infections but can also contribute to non-infectious diseases.
• IFN pathways are implicated in organ injury and compensatory mechanisms.
• Recent interest stems from SARS-CoV-2 and the cGAS-STING pathway.

Purpose of the Study:

• To review the multifaceted roles of IFNs and related pathways in heart disease.
• To explore the impact of type I IFNs, IFN-stimulated genes (ISGs), cGAS-STING, IFN-γ, and IRF transcription factors on cardiac function.
• To assess the potential for therapeutic interventions targeting these pathways in cardiovascular conditions.

Main Methods:

• Literature review of studies on interferons and heart disease.
• Analysis of the roles of specific IFN types (Type I, Type II) and signaling pathways (cGAS-STING, IRF).
• Examination of existing and potential therapeutic strategies involving IFNs.

Main Results:

• Type I IFNs and ISGs have complex cardiac effects.
• The cGAS-STING pathway is an emerging factor in cardiovascular pathogenesis.
• IFN-γ exhibits paradoxical effects, and IRF transcription factors show varied actions.

Conclusions:

• IFN pathways present a dual role in heart disease, potentially causing damage or acting protectively.
• Understanding these complex interactions is vital for developing novel cardiovascular therapies.
• Further research is needed to translate these findings into clinical improvements for heart disease patients.
