HIV-1 GP41 neutralization domain and use thereof
View Patent ↗The invention relates to isolated monoclonal antibodies which specifically bind to the C-terminal heptad repeat region of gp41 (HR2) and neutralize an HIV-1 primary isolate.
1. An isolated monoclonal antibody which specifically binds an epitope present on a peptide consisting of the sequence Asn-Tyr-Thr-Xaa 1 -Xaa 2 -Ile-Tyr-Xaa 3 -Leu-Xaa 4 -Glu-Xaa 5 -Ser-Gln-Asn-Gln-Gln-Glu-Xaa 6 -Asn-Glu-Xaa 7 (SEQ ID NO:26), wherein Xaa 1 is Asp or Asn; Xaa 2 is Thr or Leu; Xaa 3 is Lys, Arg, or Thr; Xaa 4 is Leu or Ile; Xaa 5 is Lys, Asp, Glu; Xaa 6 is Glu or Lys; and Xaa 7 is Lys or Gln.
2. The isolated monoclonal antibody of claim 1 , wherein said antibody neutralizes at least one HIV-1 primary isolate.
3. The isolated monoclonal antibody of claim 2 , wherein said HIV-1 primary isolate is from clade A, clade B, clade C, clade D, or clade E.
