SARS-CoV-2 spike (S) protein is a key target for eliciting neutralizing antibodies. a Schematic structures of SARS-CoV-2 virion and its S protein. M, membrane; E, envelope; N, nucleocapsid. Viral RNA is located inside the virion. NTD, N-terminal domain; RBD, receptor-binding domain; FP, fusion peptide; HR1 and HR2, heptad region 1 and 2; TM, transmembrane domain; IC, intracellular tail. b Mode of action of SARS-CoV-2 S-specific neutralizing antibodies. Monoclonal antibodies (mAbs) targeting S protein NTD prevent conformational changes of the S protein that are required for S2-mediated membrane fusion, and hence inhibit viral entry into host cells. RBD-targeting neutralizing mAbs or nanobodies (Nbs), on the other hand, bind directly to SARS-CoV-2 S protein RBD and compete with the cellular receptor, angiotensin converting enzyme 2 (ACE2), resulting in neutralization of viral infection and clearance of the virus. The following PDB entries are used for structural illustrations: 7C2L (structure of SARS-CoV-2 S in complex with NTD-targeting mAb 4A8), 7K4N (structure of SARS-CoV-2 S in complex with RBD-targeting mAb S2E12), 7KKK (structure of SARS-CoV-2 S in complex with RBD-targeting nanobody Nb6), and 6VW1 (structure of SARS-CoV-2 RBD in complex with human ACE2). SARS-CoV-2 S NTD is colored in orange, RBD in green, and the rest part of S protein in light blue. ACE2 is colored in purple.
