A Fc-enhanced NTD-binding non-neutralizing antibody delays virus spread and synergizes with a nAb to protect mice from lethal SARS-CoV-2 infection
Emerging evidence indicates that both neutralizing and Fc-mediated effector functions of antibodies contribute to protection against SARS-CoV-2. It is unclear whether Fc-effector functions alone can protect against SARS-CoV-2. Here, we isolated CV3-13, a non-neutralizing antibody, from a convalescen...

description | Emerging evidence indicates that both neutralizing and Fc-mediated effector functions of antibodies contribute to protection against SARS-CoV-2. It is unclear whether Fc-effector functions alone can protect against SARS-CoV-2. Here, we isolated CV3-13, a non-neutralizing antibody, from a convalescent individual with potent Fc-mediated effector functions. The cryoelectron microscopy structure of CV3-13 in complex with the SARS-CoV-2 spike reveals that the antibody binds from a distinct angle of approach to an N-terminal domain (NTD) epitope that only partially overlaps with the NTD supersite recognized by neutralizing antibodies. CV3-13 does not alter the replication dynamics of SARS-CoV-2 in K18-hACE2 mice, but its Fc-enhanced version significantly delays virus spread, neuroinvasion, and death in prophylactic settings. Interestingly, the combination of Fc-enhanced non-neutralizing CV3-13 with Fc-compromised neutralizing CV3-25 completely protects mice from lethal SARS-CoV-2 infection. Altogether, our data demonstrate that efficient Fc-mediated effector functions can potently contribute to the in vivo efficacy of anti-SARS-CoV-2 antibodies.

•Non-neutralizing antibody CV3-13 binds an epitope in NTD of SARS-CoV-2 spike•CV3-13 has a unique angle of approach and mediates potent Fc-effector functions•Fc-enhanced CV3-13 delays virus spread and death in SARS-CoV-2-challenged mice•Fc-enhanced CV3-13 synergizes with Fc-compromised nAb to protect 100% of the mice
The in vivo impact of non-nAbs on SARS-CoV-2 infection is unclear. Here, Beaudoin-Bussières et al. show that a Fc-enhanced version of non-nAb CV3-13 delays SARS-CoV-2 spread and death in mice. Fc-enhanced CV3-13 combined with a Fc-compromised nAb synergizes to protect mice, revealing the importance of non-nAbs during SARS-CoV-2 infection. |

•Non-neutralizing antibody CV3-13 binds an epitope in NTD of SARS-CoV-2 spike•CV3-13 has a unique angle of approach and mediates potent Fc-effector functions•Fc-enhanced CV3-13 delays virus spread and death in SARS-CoV-2-challenged mice•Fc-enhanced CV3-13 synergizes with Fc-compromised nAb to protect 100% of the mice
The in vivo impact of non-nAbs on SARS-CoV-2 infection is unclear. Here, Beaudoin-Bussières et al. show that a Fc-enhanced version of non-nAb CV3-13 delays SARS-CoV-2 spread and death in mice. Fc-enhanced CV3-13 combined with a Fc-compromised nAb synergizes to protect mice, revealing the importance of non-nAbs during SARS-CoV-2 infection.</abstract><cop>United States</cop><pub>Elsevier Inc</pub><pmid>35123652</pmid><doi>10.1016/j.celrep.2022.110368</doi><tpages>1</tpages><orcidid>https://orcid.org/0000-0002-6901-5601</orcidid><orcidid>https://orcid.org/0000-0003-3277-568X</orcidid><orcidid>https://orcid.org/0000-0001-9966-3784</orcidid><orcidid>https://orcid.org/0000-0001-5380-2339</orcidid><orcidid>https://orcid.org/0000-0002-4442-8442</orcidid><orcidid>https://orcid.org/0000-0003-0594-5057</orcidid><orcidid>https://orcid.org/0000-0001-9153-3600</orcidid><orcidid>https://orcid.org/0000-0001-8211-6207</orcidid><orcidid>https://orcid.org/0000-0002-1106-7097</orcidid><orcidid>https://orcid.org/0000-0002-7760-8693</orcidid><orcidid>https://orcid.org/0000-0002-8565-1106</orcidid><orcidid>https://orcid.org/0000-0002-7236-858X</orcidid><oa>free_for_read</oa></addata></record> |
