The mechanism by which the SARS-CoV-2 virus infects host cells is complex, and the fusion peptide is central to this process. Following the initial binding of the virus to host cell receptors, primarily ACE2 for SARS-CoV-2, a conformational change occurs in the spike protein. This change exposes the fusion peptide, which then inserts itself into the host cell membrane. This insertion destabilizes the membrane, facilitating the merging of the viral envelope with the cellular membrane. This event is crucial for the virus to bypass the cell's defenses and initiate a productive infection. The fusion peptide of SARS-CoV-2 spike is essential for infection, as its absence or malfunction would severely impair the virus's ability to enter cells.

The broader implications of understanding the SARS-CoV-2 fusion peptide extend to comparative virology. The fusion peptide is not unique to SARS-CoV-2; it is a conserved feature across many coronaviruses, including SARS-CoV and MERS-CoV. This conservation suggests that strategies targeting the fusion peptide could offer broad-spectrum protection against related viruses. For instance, antibodies targeting the fusion peptide appear partially surface-exposed in a range of coronavirus spike proteins.作者：C Zannella·2023·被引用次数：3—We found that the FPpeptideconjugated to the dendrimer, unlike the monomeric FP sequence, has virucidal activity by impairing the attachment ofSARS-CoV-2to ...
