The cGAS-STING pathway: Post-translational modifications and functional implications in diseases

Area of Science:

• Immunology
• Molecular Biology
• Genetics

Background:

• DNA recognition is crucial for innate immune responses in various diseases.
• The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway modulates immune responses via type I interferons (IFNs).
• Post-translational modifications (PTMs) significantly influence cGAS-STING pathway activity.

Purpose of the Study:

• To review the regulation of the cGAS-STING pathway.
• To explore the role of cGAS-STING signaling in disease pathologies.
• To discuss therapeutic strategies targeting the cGAS-STING pathway.

Main Methods:

• Literature review of studies on cGAS-STING pathway regulation.
• Analysis of PTMs affecting cGAS-STING function.
• Examination of cGAS-STING's role in diverse disease contexts.
• Identification of pharmacologic targets within the pathway.

Main Results:

• The cGAS-STING pathway plays a dual role (protective or pathogenic) in disease development.
• PTMs are critical regulators of cGAS-STING signaling.
• Dysregulation of cGAS-STING is implicated in numerous pathologies.
• Targeting the cGAS-STING pathway offers therapeutic potential.

Conclusions:

• A comprehensive understanding of cGAS-STING PTMs and their disease implications is essential.
• Insights into cGAS-STING regulation can aid in predicting disease progression.
• Pharmacologic interventions targeting cGAS-STING may lead to novel disease treatments.
