Fusion is the process by which a virus merges its envelope with the host cell membrane to deliver its genetic material into the cell. This is a critical initial step for many viral infections.
5 Must Know Facts For Your Next Test
Fusion typically occurs at the plasma membrane or within endosomes after endocytosis.
Many enveloped viruses, such as HIV and influenza, utilize fusion to enter host cells.
Fusion proteins on the viral envelope facilitate this merging process by undergoing conformational changes.
The pH level of the environment can trigger or inhibit fusion, influencing viral entry success.
Inhibitors targeting fusion proteins are a strategy for antiviral drug development.
