Summary
Caveolae mediate viral entry into cells, a process previously debated. Real-time imaging confirms caveolae facilitate Simian virus 40 and human coronavirus-229E cellular uptake via endocytosis.
Area of Science:
- Cell Biology
- Virology
Context:
- The endocytic role of caveolae in cellular processes has been a long-standing debate in cell biology.
- Understanding viral entry mechanisms is crucial for developing antiviral strategies.
Purpose:
- To review and synthesize evidence on the involvement of caveolae in endocytosis during viral entry.
- To clarify the controversial role of caveolae in cellular uptake mechanisms.
Summary:
- Real-time imaging demonstrates Simian virus 40 (SV40) entry via caveolar endocytosis, involving dynamin-dependent budding.
- SV40-containing caveolae vesicles traffic to caveosomes and then to the endoplasmic reticulum.
- Human coronavirus-229E (HCoV-229E) entry into cells also occurs through caveolae.
Impact:
- Provides critical insights into the mechanisms of viral cellular entry.
- Highlights caveolae as a significant pathway for specific viral infections.
- Informs potential therapeutic targets for viruses utilizing caveolar pathways.
