Compositions and methods for the therapy and diagnosis of influenza
The present invention provides novel human anti-influenza antibodies and related compositions and methods. These antibodies are used in the diagnosis and treatment of influenza infection.
1. A method for the treatment of an influenza A virus infection in a subject, comprising administering to the subject a composition comprising an isolated anti-matrix 2 ectodomain (M2e) antibody, wherein the M2e is of an influenza A virus, and wherein the antibody comprises,
a) a V H CDR1 region comprising the amino acid sequence of NYYWS (SEQ ID NO: 72); a V H CDR2 region comprising the amino acid sequence of FIYYGGNTKYNPSLKS (SEQ ID NO: 74); a V H CDR3 region comprising the amino acid sequence of ASCSGGYCILD (SEQ ID NO: 76); a V L CDR1 region comprising the amino acid sequence of RASQNIYKYLN (SEQ ID NO: 59); a V L CDR2 region comprising the amino acid sequence of AASGLQS (SEQ ID NO: 61); a V L CDR3 region comprising the amino acid sequence of and QQSYSPPLT (SEQ ID NO: 63), or
b) a V H CDR1 region comprising the amino acid sequence of SNYMS (SEQ ID NO: 103); a V H CDR2 region comprising the amino acid sequence of VIYSGGSTYYADSVK (SEQ ID NO: 105), a V H CDR3 region comprising the amino acid sequence of CLSRMRGYGLDV (SEQ ID NO: 107); a V L CDR1 region comprising the amino acid sequence of RTSQSISSYLN (SEQ ID NO: 92); a V L CDR2 region comprising the amino acid sequence of AASSLQSGVPSRF (SEQ ID NO: 94); and a V L CDR3 region comprising the amino acid sequence of QQSYSMPA (SEQ ID NO: 96).
