Abstract

Graphical abstract: Highlights: A summary of the effects of lysosomal ion channels on the cellular entry and uncoating of enveloped viruses. Lysosomal channels represent an exciting and emerging target for therapeutic strategies against enveloped viruses. Further investigation may aid in development of novel therapies against SARS-CoV-2. Abstract: Ion channels are necessary for correct lysosomal function including degradation of cargoes originating from endocytosis. Almost all enveloped viruses, including coronaviruses (CoVs), enter host cells via endocytosis, and do not escape endosomal compartments into the cytoplasm (via fusion with the endolysosomal membrane) unless the virus-encoded envelope proteins are cleaved by lysosomal proteases. With the ongoing outbreak of severe acute respiratory syndrome (SARS)-CoV-2, endolysosomal two-pore channels represent an exciting and emerging target for antiviral therapies. This review focuses on the latest knowledge of the effects of lysosomal ion channels on the cellular entry and uncoating of enveloped viruses, which may aid in development of novel therapies against emerging infectious diseases such as SARS-CoV-2.
