coxir-peptide The ongoing battle against coronaviruses has spurred significant research into developing effective countermeasures.Broadly Neutralizing Antibodies to SARS-CoV-2 Provide ... A critical area of investigation focuses on broadly neutralizing antibodies (bnAbs), which possess the remarkable ability to neutralize a wide spectrum of coronaviruses, including various strains of SARS-CoV-2 and other human and animal coronaviruses. Emerging scientific evidence, notably from research published in *Science* in 2022, highlights that these potent bnAbs often target a conserved region within the coronavirus fusion peptideBroadly neutralizing antibodies against COVID-19. This specific targeting mechanism is proving to be a promising avenue for developing universal vaccines and therapeutics against this ever-evolving viral family.

The fusion peptide (FP) is a crucial component of the viral spike protein, playing a pivotal role in the virus's ability to infect host cells. It is essential for mediating the fusion of the viral membrane with the host cell membrane, a process that allows the virus to enter and replicate.Overview of Neutralizing Antibodies and Their Potential in COVID-19 - NIH Because the fusion peptide is relatively conserved across different coronavirus species, it represents a "site of vulnerability" for the virus. This conserved nature makes it an attractive target for antibodies that aim for broad protective capabilities.and vaccine-elicited antibodies against the fusion peptide of HIV Indeed, studies have shown that all six antibodies investigated in some research target the conserved fusion peptide region adjacent to the S2' cleavage site.1 SARS-CoV-2 Fusion Peptide-Directed Antibodies Elicited ...

The significance of targeting the fusion peptide lies in its potential to confer cross-protection.作者：R Lei·2024·被引用次数：23—Broadly neutralizing antibodies target the coronavirus fusion peptide. Science 377, 728–735 (2022). Article ADS CAS PubMed Google Scholar. Unlike antibodies that focus on more variable regions of the spike protein, such as the Receptor Binding Domain (RBD), bnAbs that target the fusion peptide can maintain their efficacy against a broader range of viral variants. This is because the fusion peptide's function is so fundamental to viral entry that mutations there are often detrimental to the virus's own survival. Research has demonstrated that broadly neutralizing antibodies target the coronavirus fusion peptide and can effectively neutralize not only SARS-CoV-2 but also other betacoronaviruses.作者：Y Chen·2023·被引用次数：385—Unlike the neutralization mechanism of antibodies targeting S1,S2P6 can inhibit SARS-CoV-2 infectionby preventing S protein-mediated fusion of ... For instance, specific antibodies, like those targeting the fusion peptide, have shown the capacity to inhibit SARS-CoV-2 infection by preventing S protein-mediated fusion.1 SARS-CoV-2 Fusion Peptide-Directed Antibodies Elicited ...

Furthermore, the discovery that ACE2-binding exposes the SARS-CoV-2 fusion peptide to broadly neutralizing coronavirus antibodies provides crucial insight into the dynamics of viral entry and antibody recognition. When the virus binds to the ACE2 receptor on host cells, it triggers conformational changes in the spike protein, revealing the fusion peptide and making it accessible to neutralizing antibodies.Broadly neutralizing antibodies target the coronavirus fusion peptidescience.org. This interaction underscores the importance of the fusion peptide as a target. The development of fusion peptide (FP)-specific monoclonal antibodies (mAbs) holds immense potential. These antibodies, identified from individuals who have recovered from COVID-19, demonstrate broad neutralizing activity against a wide array of human coronaviruses.Perspectives on the development of neutralizing antibodies ...

The concept of targeting the fusion peptide is not entirely novel; similar strategies have been explored for other viruses, such as HIV-1, where the fusion peptide of HIV-1 has been identified as a site of vulnerability to neutralizing antibody. This historical context lends further credence to the approach for coronaviruses作者：JS Low·2022·被引用次数：170—Despitetargetinga conserved motif, only some mAbs show broadneutralizingactivity in vitro against alpha- and betacoronaviruses, including animal .... The potential of Pan-betacoronavirus neutralizing antibodies is particularly exciting, as they may hold the key to developing broadly protective vaccines against future pandemic coronaviruses.

While antibodies targeting the Receptor Binding Domain (RBD) are common, they often struggle to maintain potency against emerging variants due to mutations in this region. In contrast, broadly neutralizing antibodies targeting the fusion peptide offer a more stable and universal approach. Understanding how these bnAbs retain potency in the face of viral evolution is a critical area of ongoing research. The identification of such antibodies is crucial for developing next-generation coronavirus vaccines and treatments.

In summary, the fusion peptide represents a highly conserved and vulnerable target on the coronavirus spike protein. Broadly neutralizing antibodies that specifically target this region are demonstrating significant potential to neutralize a wide array of coronaviruses, offering a promising path towards universal protection against current and future viral threats.作者：R Lei·2024·被引用次数：23—Broadly neutralizing antibodies target the coronavirus fusion peptide.
