Therapeutic Potential of Exploiting Autophagy Cascade Against Coronavirus Infection

Area of Science:

• Virology
• Cell Biology
• Immunology

Background:

• Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused a global pandemic, leading to millions of cases and deaths.
• Coronaviruses, including SARS-CoV-2, exploit host cell autophagy for viral replication and pathogenesis.
• Autophagy, a cellular degradation process, involves double-membrane vesicles crucial for viral replication complex assembly.

Purpose of the Study:

• To review the current understanding of the link between autophagy and coronaviruses.
• To explore the potential of repurposing autophagy modulators as therapeutic agents for COVID-19.
• To address the urgent need for safe and effective treatments against SARS-CoV-2 infection.

Main Methods:

• Literature review of studies on autophagy and coronavirus interactions.
• Analysis of existing research on autophagy inhibitors (e.g., chloroquine) for COVID-19 treatment.
• Discussion of the role of autophagy modulation in combating SARS-CoV-2.

Main Results:

• Autophagy plays a critical role in the replication cycle of SARS-CoV-2.
• Initial therapeutic strategies using autophagy inhibitors like chloroquine showed promise but were limited by cytotoxicity.
• Targeting the autophagy pathway presents a viable avenue for developing novel COVID-19 treatments.

Conclusions:

• The intricate relationship between autophagy and viral pathogenesis highlights its significance in COVID-19.
• Repurposing autophagy modulators offers a promising strategy for developing safe and affordable treatments.
• Further research into autophagy modulation is crucial for effective COVID-19 therapeutic development.
