Abstract:
Coronavirus disease 2019 (COVID-19), caused by a new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has instantaneously emerged as a worldwide pandemic. However, humans encountered other coronaviruses in the past, and they caused a broad range of symptoms, from mild to life-threatening, depending on the virus and immunocompetence of the host. Most human coronaviruses interact with the proteins and/or double-membrane vesicles of autophagy, the membrane trafficking pathway that degrades and recycles the intracellular protein aggregates, organelles, and pathogens, including viruses. However, coronaviruses often neutralize and hijack this pathway to complete their life cycle. In this review, we discuss the interactions of human coronaviruses and autophagy, including recent data from SARS-CoV-2-related studies. Some of these interactions (for example, viral block of the autophagosome-lysosome fusion), while being conserved across multiple coronaviruses, are accomplished via different molecular mechanisms. Therefore, it is important to understand the molecular interplay between human coronaviruses and autophagy for developing efficient therapies against coronaviral diseases.
Insights
Human coronaviruses, including SARS-CoV-2, hijack cellular autophagy for replication. Understanding these interactions is key to developing effective therapies against COVID-19 and other coronavirus diseases.
Area of Science:
- Virology
- Cell Biology
- Immunology
Background:
- Coronaviruses, including SARS-CoV-2, cause a spectrum of diseases.
- Autophagy is a cellular process for degrading waste and pathogens.
- Coronaviruses often manipulate autophagy for their life cycle.
Purpose of the Study:
- To review the interactions between human coronaviruses and autophagy.
- To highlight conserved and divergent mechanisms of viral hijacking.
- To emphasize the importance of this interplay for therapeutic development.
Main Methods:
- Literature review of existing studies on coronaviruses and autophagy.
- Analysis of recent data specific to SARS-CoV-2.
- Comparison of molecular mechanisms across different coronaviruses.
Main Results:
- Coronaviruses interact with autophagy proteins and vesicles.
- Viruses frequently subvert autophagy, for instance, by blocking autophagosome-lysosome fusion.
- Mechanisms of interaction can differ even for conserved pathways.
Conclusions:
- Understanding the molecular interplay between coronaviruses and autophagy is crucial.
- Targeting these interactions may lead to novel therapies for coronavirus infections.
- Further research is needed to elucidate specific mechanisms for therapeutic intervention.
