The Role of the Nuclear Factor-Kappa B (NF-κB) Pathway in SARS-CoV-2 Infection

Area of Science:

• Immunology
• Virology
• Molecular Biology

Background:

• COVID-19, caused by SARS-CoV-2, presents a significant global health challenge with high morbidity and mortality.
• Nuclear factor-kappa B (NF-κB) is a critical regulator of immune and inflammatory responses.
• Dysregulation of NF-κB signaling is implicated in the pathogenesis of various viral infections, including potentially SARS-CoV-2.

Purpose of the Study:

• To review the role of NF-κB activation in the context of COVID-19.
• To explore the potential of targeting NF-κB pathways as a therapeutic strategy against SARS-CoV-2.
• To detail the involvement of NF-κB in SARS-CoV-2 pathogenesis.

Main Methods:

• Literature review of studies investigating NF-κB pathways.
• Analysis of the molecular mechanisms linking NF-κB activation to SARS-CoV-2 infection.
• Discussion of potential therapeutic interventions targeting NF-κB.

Main Results:

• NF-κB plays a central role in the inflammatory response during SARS-CoV-2 infection.
• Aberrant NF-κB activation contributes to the cytokine storm observed in severe COVID-19.
• Specific NF-κB pathways are activated by SARS-CoV-2, influencing viral replication and host response.

Conclusions:

• Modulating NF-κB activation presents a promising therapeutic avenue for managing COVID-19.
• Further research into NF-κB intricacies is crucial for developing effective anti-SARS-CoV-2 treatments.
• Targeting NF-κB could mitigate the severe inflammatory consequences of COVID-19.
