COVID-19 signalome: Potential therapeutic interventions

Area of Science:

• Virology and Immunology
• Drug Discovery and Development

Background:

• The COVID-19 pandemic spurred rapid vaccine and drug development against SARS-CoV-2.
• Vaccine efficacy is threatened by emerging SARS-CoV-2 variants, necessitating new therapeutic strategies.
• Initial drug development relied heavily on repurposing existing antivirals.

Approach:

• This review expands SARS-CoV-2 target identification beyond surface proteins (Spike, envelope, membrane, nucleoprotein).
• It investigates the COVID-19 signalome, including viral proteases.
• The study examines host cell signaling pathways as potential drug targets.

Key Points:

• SARS-CoV-2 variants pose a significant challenge to current vaccine effectiveness.
• Viral proteases offer viable targets for inhibiting viral replication.
• Signaling pathways such as the renin-angiotensin system, immune pathways, hypoxia, and calcium signaling are promising for drug development.

Conclusions:

• Exploring the COVID-19 signalome provides alternative targets for more effective drug development.
• Targeting host cell receptors and viral proteases is crucial for combating SARS-CoV-2.
• New therapeutic strategies are essential to address the threat of emerging SARS-CoV-2 variants.
